Q

all of the chemical reactions that occur in the body to maintain itself. Metabolism is the process in which nutrients are acquired, transported used and disposed of by the body

A

Metabolism

1
Q

the study of energy in the human body

A

bioenergetics

2
Q

the material or substance on which an enzyme acts (carbs, proteins, fats)

A

substrates

3
Q

organic compounds of carbon , hydrogen, and oxygen, which includes starches, cellulose and sugars, and are important source of energy. All carbs are eventually broken down in the body to glucose, a simple sugar

A

Carbohydrates

4
Q

a simple sugar manufactured by the body from carbs, fat and to a lesser extent protein, which serves as the bodys main source of fuel

A

Glucose

5
Q

the complex carb molecule used to store carbs in the liver and muscle cells. When carb energy is needed glycogen is converted into glucose for use by the muscle cells

A

glycogen

6
Q

one of the three main classes of foods and a source of energy in the body. Fats help the body use some vitamins and keep the skin healthy. They also serves as energy stores for the body. In food, there are two types of fat: unsaturated and saturated

A

Fat

7
Q

the chemical or substrate form in which most fat exists in food as well as in the body

A

triglycerides

8
Q

amino acids linked by peptide bonds, which consist of carbon, hydrogen, nitrogen, oxygen and usually sulfur and that have several essential biologic compounds

A

Protein

9
Q

the formation of glucose from noncarbohydrate sources, such as amino acids

A

gluconeogenesis

10
Q

energy storage and transfer unit within the ells of the body

A

ATP

11
Q

a high energy compound occurring in all cells from which ATP is formed

A

ADP

12
Q

the breakdown of triglycerides into smaller subunits called free fatty acids (FFAs) to convert FFAs into acyl-CoA molecules which then are available to enter the krebs cycle and ultimately lead to the production of additional ATP

A

Beta Oxidation

13
Q

the state in which the bodys metabolism is elevated after exercise

A

excessive postexercise oxygen consumption (EPOC)
