Linkage Analysis Essay

The concept of energy intake and expenditure refers to the amount of calories per day that an individual consumes, and is the chemical energy in foods which can be metabolized to produce energy available to the body. As stated before energy is obtained from the foods we eat and is used to support an individual’s Basal Metabolic Rate, energy is measured in calories or joules as both units are very small they are multiplied by 1,000 and referred to as kilocalories. Different foods provide us with different amounts of energy, and the potential fuel sources available to exercising muscles are fats – 1 gram fat =9.0kcal = 23kJ,

Genetics can play a role in obesity. “Offspring of obese parents are much more likely to become obese than offspring of lean parents”, according to what Kris Gunnars wrote on https://www.healthline.com. Even though our future cannot be determined by our genes, genes can have a major

Genes control almost every aspect of human life, and when it comes to weight there is no exception. Little is known, however, how much of an individual’s genes actually control the weight of certain individuals. Body fat can vary from person to person, yet some people have always carried more weight than others. Often times, when one person is overweight in the family, most of the other individuals in the same family are overweight as well. However, more than just genetics can go into being overweight, and a person’s genes are not the end all be all of obesity. Many times the environment surrounding people who are obese contributes to the overall weight of the individual, and when obesity promoting genes are mixed

Child obesity is alarmingly prevalent in the United States today; approximately 18 percent of adolescents are considered obese. Obesity is defined as “one of the most pervasive chronic diseases...that affects more than one-third of the population” (Source 2). While obesity may be a major challenge facing adults in the United States, adolescents are facing a similar struggle. More than 33 percents of all children and teens suffer from obesity. But why is child obesity such a major problem in the United States? Though obesity has been shown to have some genetic inheritance between parents and offspring. Adolescents are regularly eating fatty and unhealthy foods, and are not getting the

Food provides the energy in the form of calories as well as the materials needed to build and maintain all body cells.

In this assignment I will be explaining the physiology of two named body systems in relation to energy metabolism in the body, the Respiration system and the Digestive system. I will start off by giving a definition of energy metabolism in the body. Metabolism in the body is a collection of chemical reactions that takes place in the body’s cells. Metabolism converts the nutrients in the food that we eat in to essential energy which is needed to power all that we do, from something as little as thinking to growing physically or carrying out a physical activity. In our body’s, there are a specific protein which controls the

What are their functions?Carbohydrates- simple sugar. They are composed of carbon, hydrogen and oxygen. They are also monosaccharides.Lipids- They are fats, oils and steroids. Lipids store energy and also helps in the synthesis of vitamins and hormones.Proteins- They are a long chain of amino acids. They are the most complex and most diverse chemical composition.Functions of carbohydrates, lipids and proteins Carbohydrates- provides energy as they are the bod’s main source of fuel, needed for physical activity.Lipids- Lipids are used for storage of energy and forming cell membranes.Proteins- They do most of the work in cells and are required for the structure, function, and regulation of body tissue and organWhat do they look like?Lipids- They have long hydrocarbon chains that determine the way they act.Carbohydrates- Molecules combines of carbon, hydrogen and oxygen.Protein- A long chain of amino acids combined.48. What is metabolism? How are carbohydrates, lipids, and proteins metabolized? What role does enzymes play in metabolisms?Metabolism is the chemical process that occur within a living organism in order to maintain life.Carbohydrate metabolism- begins with digestion in the small intestine where monosaccharides are absorbed into the blood stream. Blood sugar concentrations are controlled by three hormones: insulin, glucagon, and epinephrine. If the concentration of glucose in the blood is too high, insulin is secreted by the pancreas.Lipid metabolism- are involved with Fatty Acid Oxidation to produce energy or the synthesis of lipids which is called Lipogenesis. Lipid metabolism is closely connected to the

A person’s genetic make up has a significant influence on whether the person will become obese or not. If both parents are obese, the likelihood that their children may end up being obese too is higher compared to a situation where neither of the parents is obese or where only one of the parents is obese. This is particularly so because genetics influence the way the body stores energy and how energy is used. This can be seen in the differences that have recorded in the basal metabolic rates (BMR) among groups of people who differ by age, gender and the make up of their bodies. People who have a low metabolic rate have a higher risk of becoming overweight. The genetic similarities shared by members of one family can explain why people who come form certain families end up being overweight (DeBruyne, Pinna

Obesity has been linked to genetics. It has been researched and proven that children with parents who are obese, would have between 5-25% chance of likely inheriting genes that would eventually make them obese. However, genes is not an excuse for obesity because it does not work alone but must have the right factors present to manifest.

indicate that inherited genetic variation is an important risk factor for obesity. It was also pointed

The causation of obesity is multifactorial. Genetic and environment factors play a crucial role in the involvement of childhood obesity and a superior role when combined.

If we do not use all of the sugar (glucose) that the body has received, the extra stuff is stored to be used later in the liver and muscles and eventually, if we still don't use it all, it stores it in our fat banks. Some of us have "fat banks" on our thighs and but, while others of us have them in the belly, arms chest etc. We can't change where our body stores this extra "energy" but we can change how much it stores.

The body uses carbohydrates directly from the monosaccharide glucose. Glucose is in the blood and extracellular fluids (lymph) and can be made from glycogen. Glycogen is stored in the liver and muscles and in smaller amounts in the other organs and tissues of the body. Energy is derived from glucose by the splitting of the glucose molecules into smaller compounds and oxidizing these to form water, which frees quite a large amount of

It’s been shown that children with obese parents are more likely to become obese. Heredity contributes between 5-25 percent risks of obesity. Other risks can be attributed to the environment and behavior. Obesity is generally linked to over eaten but in most cases its heredity problem children should be careful because genes can also pass to their offspring. The problem cannot be corrected but you can prevent it. Children should be given an appropriate diet and should be deterred from overeating. Child obesity can be predicted at an early stage and children should be aware of the consequences of obesity.

Everybody knows the child that can eat any type of food all day and never seem to gain weight. This occurrence has led researchers to investigate the role that genetics plays in childhood obesity. Not all children who are inactive or who eat poorly are obese, much in the same way that some obese children eat fairly healthy, and exercise moderately. Heredity has recently been shown to influence body fat percentage, regional fat storage, and the body?s response to overeating (Rush, 1). Children who have obese parents are 80% more likely to be obese than their lean parented counterparts (Buffington, 16). This familial correlation is contributed to genetics as well as the parents eating habits. Children with obese parents typically aren?t taught the correct way to choose when and what food to eat, leading to poor eating habits and eventually obesity. Many genetic defects can have a significant effect on obesity such as variable thyroid activity and pituitary defects. Abnormalities in any one of these regulators could be responsible for appetite abnormalities and weight gain. Furthermore, obesity leads to defects in appetite regulation, hormone production, and metabolic events (Oklahoma Cooperative, 4) that are responsible for further weight gain,
