a. Proteins
• made of amino acids
• main functions - cell synthesis and repair, energy as needed
• examples - soy, beans, legumes, nuts, seeds, animal products (milk, meats, cottage cheese, etc.)
b. Carbohydrates
• made of carbon, hydrogen, oxygen
• main functions - primary energy source, fat and protein metabolism, energy reserves in stored glycogen, blood glucose fuels brain and CNS
• examples - starch, sugars (breads, pasta, starchy vegetables, fruit sugars, simple sugars, etc.)
c. Fats
• made of fatty acids glycerol
• main functions
• saturated sources (dairy products, meat, margarine, chocolate, coconut oil, etc.), unsaturated/MUFAs/PUFAs sources (safflower/olive/soybean oils, tuna, salmon, etc.)

This homeostasis is controlled by individual fat cells and when they get smaller it sends a signal to the brain to eat.
3.
Metabolism is the sum of all chemical reactions that take place in the body and how fast the body utilizes the calories that we put into it. Body weight increases and decreases based on the amount of calories put in and the amount of energy we burn.
4.
Increasing muscle mass does increase metabolism because all muscles have a resting energy requirement and more muscle utilizes more energy.
5.
A diuretic is any substance that increases the amount of fluid excreted as urine. This can have a negative effect on homeostasis because it can make the fluid that the body actually needs leave too.
6.
Exocrine glands, the liver and the kidneys remove toxins. A toxin is a biological poison. Some toxins are known to be stored in fat cells so it could be true that the more fat we have in our body the more toxic our body may become.

Yes, Mitchell has a body image problem. More health risks that can result from this are irregular heartbeat, heart failure, gastric rupture in a case of binging, dehydration, tooth decay, irregular bowel movements or constipation, peptic ulcers and pancreatitis. Part 3
1. Carbohydrates are made up of sugars.
2. Blood carries sugar in its stream for energy. Diabetes is a metabolic disease in which carbohydrate use is reduced and that of
Obesity in the United States is a major issue. Because there is such a high obesity rate, there have been so many diets established to try and reduce these constantly rising rates. A lot of these weight-loss diets that have been established are known as fad diets. A fad diet is a diet that becomes popular quickly, and may die out just as quickly. In the United States, there are some popular and healthy fad diets such as the Atkins diet, the South Beach diet, and Weight Watchers.
Energy metabolism is where the nutrients oxygen and glucose are took in and delivered the organs. Energy is needed in order for our body to be able to function. Energy helps break down molecules and to build new molecules.
3. What is “metabolism”? What does human metabolism have to do with energy balance and body weight? Answer: metabolism- the chemical processes that occur within a living organism in order to maintain life. Food is measured in calories which the body processes as energy. Additional calories must be burned through exercise or physical activity or it will be stored as fat.
Carbohydrates are composed of carbon, hydrogen, and oxygen. Carbohydrates can come from fruits, vegetables, and grains. There are two different kinds of carbohydrates. The first being simple carbohydrates, which are sugars. Glucose, fructose, and galactose fall under the sugar category. Then you have your complex carbohydrates, which are starch in grains, glycogen stored in our muscles, and fiber. When it comes to energy within our body glucose is a major source of energy. When our body does not get enough carbohydrates to supply enough glucose, our body will make glucose from proteins. I applied this to my life by making sure I eat fruits, vegetables, and grains to get my carbohydrates every single
Carbohydrates are macromolecules which and contains carbon, hydrogen and oxygen (C,H,O). There are also two types of sugars, sweet soluble and starches which are non-soluble. Sugars can also be single or simple sugars.Carbohydrates can be found in a wide variety of foods such as pasta, wheat and grains, rice, potatoes, fruits and sugars. Carbohydrates are broken down into
Metabolism is a chemical process that converts fuel from food into energy needed for the body’s activities. For example, thinking, running and jumping etc. are all an example of the bodies activities.
Two friends of yours, Janine and Mitchell, join you at lunch. During your conversation, Janine comments on Mitchell’s choice of food: a small bowl of cottage cheese, a chicken salad with vinegar and oil dressing, and a glass of ice water.
Homeostasis is described as the body's ability to maintain internally stable conditions. Each organ plays a huge role in maintaining this stability.
“Metabolism is the set of chemical reactions that happen in living organisms to maintain life. These processes allow organisms to grow and reproduce, maintain their structures, and respond to their environments” (Metabolism). Metabolism breaks down the food that we eat, transforming it into energy for our bodies. Metabolism is broken down into two categories Anabolism and Catabolism, which help aid in the chemical reaction process. Specific proteins in the body control the chemical reactions of metabolism, and each chemical reaction is coordinated with other body functions (Dowshen). Metabolism is a constant process that begins when we're born and ends when we die. It is a vital process for all life not just humans, and
Diabetes is a common chronic disease that causes problems in the way the blood uses food. The inability of the body to transform the sugar into energy is called diabetes. Glucose, a simple sugar, is the primary source of fuel for our bodies. When food is digested, some of the food will be converted into glucose which is then transferred from the blood into the cells however, insulin, which is produced by beta cells in the pancreas is needed. In individuals with diabetes, this process is impaired.
There is a pair of kidneys in the human body. They are situated towards the back of the body under the ribs, just at the level of the waist where one on either side of the body. Each kidney is composed of about one million units which are called nephrons and each nephron consists of two parts: a filter which is called the glomerulus and a tubule leading out from the nephron (Cameron 1999). According to Marshall and Bangert (2008) the kidneys have three major functions. Firstly, the kidneys are excretion of waste from plasma in the blood. The second function is that, they maintain of extracellular fluid volume and composition. Lastly, the kidneys have a role in hormone synthesis.
The endocrine system is a biological system of complex organisms that involves sending chemical signals from one gland to another part of the body through blood. The endocrine system involves the use of several chemicals produced in the body at different parts sent to other parts of the body to trigger function of that that organ. It is a well synchronized circus of chemicals in the body to communicate the needs from one organ to the another for the efficient functioning and reproduction of the organism. Scientifically, endocrinology is defined as a study of endocrine glands and their secretions [12]. The human body has a lot of hormones that are released into the blood. In the following paper, endocrinology will be mainly addressed from a toxicological perspective. The toxicological impact of endocrine disrupting chemicals, specifically, Bisphenol A (BPA) will be discussed, following an introduction of the general endocrine system and its normal physiology.
In the body, the chemical reaction going on in the body to keep the breathing, the heart beating and brain working all of these are derive the energy from. The three main macronutrients in living system which are fats, carbohydrates (sugar), lipids (fats), protein (amino acid). Moreover also needs some minerals and vitamins, they are usually required daily in large quantities nutrients.
A fad diet is a diet that promises fast weight loss through unhealthy and unbalanced meals, they are targeted for people who manly want to lose fat without exercising and it's not good for your body. There are many types of fad diets and i'm gonna start with one the the most dangerous, the tapeworm diet. The tapeworm diet was created by Dr. Meyers of Sheffield and it started to be advertised in the early 1900’s. During the process of this diet, you are digesting tapeworm eggs and it grows in your stomach and basically crawls around eating all the food you have consumed and you are losing weight at the same time. This can be very dangerous because it could go to other parts of your body through the blood system and can cause abdominal pain, weakness, headache, nausea, diarrhoea, constipation, bloating and even death. To me it is totally disgusting and just not worth it. The tapeworm diet is thankfully illegal in the US and you usually get the tapeworm eggs in a bottle commonly found in Mexico for $1500. Back then they were usually advertised using posters saying “No diet, no baths, no exercise. FAT – the enemy that is shortening your life – BANISHED. How? With sanitized tapeworms – jar-packed” This whole diet is called unhealthy for many reasons, it is extremely risky, after the tapeworm is gone people are most likely going to gain all the weight back they lost because of unhealthy eating habits, you are not eating healthy or exercising so it's not good for your
The first fad diet that I will be talking about is the South Beach Diet. This diet includes cutting out carbs and focusing on lean protein, low-fat dairy, and good carbs whole grains, vegetables, and fruit. While the first phase of the diet is strict, the third "Maintenance" phase is meant to be a lifelong eating plan that allows you to enjoy occasional treats while maintaining a healthy weight. The person who created the diet is a Florida-based cardiologist, Arthur Agatston, MD, this diet was released in 2003. This diet cost three hundred dollars for four weeks with fully prepared meals. The South Beach Diet is advertised in commercials. These commercials tend to have pictures of people losing weight very rapidly not that realistic time frame.The commercials also tend to have famous fitness people in the commercials so that the public might believe in the diet more or are more likely to choose it over another. The South Beach Diet is actually not that bad for you.The South Beach Diet incorporates good carbs, healthy fats and plenty of lean protein. These are nutrient-dense foods that can turn off the switch for sugar and refined carb cravings. A fad diet is a diet that promises quick weight loss through what is usually an unhealthy and unbalanced diet. This diet does promise quick results and does kind of have a lack of some essential foods that we need. This diet does not require special foods, but it does require less of a lot of foods. From this I think the
