exercise metabolism and bioenergetics Flashcards
Bioenergetics
study of energy in the human body
Metabolism
process in which nutrients are acquired, transported, used, and disposed of by the body.
Exercise metabolism
bioenergetics as it relates to exercise (changes and demands placed on body)
Carbohydrates
are an important source of energy; eventually broken down in the body to glucose, a simple sugar.
Glucose
A simple sugar manufactured by the body from carbohydrates, fat, and to a lesser extent protein, which serves as the body’s main source
of fuel.
Glycogen
complex carbohydrate molecule used to store carbohydrates in the liver and muscle cells.
converted into glucose for use by the muscle cells when carbohydrate energy is needed is
Fat, two types
store energy, help the body use some vitamins and keep the skin healthy.
saturated and unsaturated
Triglycerides
form in which most fat exists in food as well as in the body.
Aerobic
requires oxygen.
Anaerobic
without oxygen.
Adenosine triphosphate (ATP)
energy storage and transfer unit within cells.
Adenosine diphosphate (ADP)
A high-energy compound occurring in all cells, used to form ATP
Anaerobic threshold
where the body can no longer produce enough energy with normal oxygen intake
Excess post oxygen consumption (EPOC)
elevation of metabolism after exercise.
β-oxidation
The breakdown of triglycerides into free fatty acids (FFAs) to convert FFAs into acyl-CoA molecules ultimately leading to the production of additional ATP.
