|
Bioenergetics |
The study of energy in the human body |
|
|
Metabolism |
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. |
|
|
Exercise metabolism |
The examination of bioenergetics as it relates to the physiologic changes and demands placed on the body during exercise |
|
|
Substrates |
The material or substance on which an enzyme acts (carbs, fats, proteins) |
|
|
Carbohydrates |
Starches, cellulose, sugars. Important source of energy. Eventually broken down into glucose, a simple sugar |
|
|
Glucose |
Simple sugar from carbohydrates and fats, which serves as the body's main source of fuel. |
|
|
Glycogen |
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 |
|
|
Fat |
One of the three main classes of foods and source of energy in the body. Helps the body use vitamins and keep the skin healthy.
Saturated and unsaturated |
|
|
Triglycerides |
The chemical or substrate form in which most fat exists in food and the body |
|
|
Protein |
Amino acids linked by peptide bonds. |
|
|
Gluconeogenesis |
The formation of glucose from non carb sources, like amino acids. |
|
|
Adenosine Triphosphate ATP |
Energy storage and transfer unit within the cells of the body |
|
|
Adenosine diphospage |
A high energy compound occuring in all cells from which ATP is formed |
|
|
Beta oxidation |
The breakdown of triglycerides into smaller subunits called free fatty acids, to convert FFAs into acyl-COA molecules. Eventually lead to the production of ATP |
|
|
Excessive postexercise oxygen consumption EPOC |
When the body's metabolism is elevated after exercise |
