Metabolism : A Machine Fueled By Activity And Temp

3. How do our bodies sometimes act like a thermostat? __When we are cold, we shiver to heat up and reach or equilibrium

In this experiment we were exposed to a variety of important concepts related to quantitative experimentation, including the proper use of glassware, and analytical balances.

In this lab experiment our main focus was to get skillful in using tools such as the metric ruler, balances, thermometer, and graduated cylinder to capture measurements of length, mass, temperature and volume. Additionally, this lab helped us to become more familiar with the uncertainty of measurements, as well as becoming efficient with rounding our measurements to the correct numbers of significant figures. Our results are measured consistently with rounding to the closest answer we could possibly acquire as the data can tell you.

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.

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.

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.

The Materials that were used to measure the experiment where a pen and paper to record the reactions of the subjects being tested, and the subjects themselves.

“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

It was observed that the hamster had a significantly greater carbon dioxide production rate than the cricket on a gram for gram basis. The greater dependence on metabolic activity for thermoregulation by the hamster, which is an endotherm, than ectotherms such as the cricket may explain this difference. Ectotherms regulate their body temperature by using heat generated from their surroundings, while endotherms use a portion of their sustenance as fuel for internal generation of heat. To maintain a body temperature typically greater than that of their surrounding environment, mammals, including hamsters, may generate heat by increasing their metabolic rate and by expressing thermogenin, an uncoupling protein in brown adipose tissue. Thermogenin transports protons into the mitochondrial matrix

Basal metabolism is the lowest level of energy transformation needed to keep the vital functions that every living organism do and spend the energy to sustain all vital. This means that it is the energy needed to work with internal organs such as the kidneys and circulatory systems such as and many others.

• The breakdown and use of food that you eat or energy that is stored in your body (metabolism).

Metabolic pathways involves the study of series of step by step chemical reactions that produce a final product(s). There are two types of metabolic pathways, pathways that require energy (anabolic) and pathways that produce energy (catabolic). All metabolic reactions do not occur spontaneously, and so need enzymes to occur.

The term metabolism refers to the different ranges of biochemical processes that can occur within a living organism but it is used commonly to refer to the breakdown of food and how this food transforms into energy that t bodies can storage it. In each individual there are processes in which substances are built up, anabolism, and there are processes in which substances are broken down, catabolism. (Medical definition of Metabolism, 2016)
