Bioenergetics & Exercising

These flashcards cover key terms and concepts related to bioenergetics and exercise physiology.

Bioenergetics

The study of chemical pathways that convert substrates to energy within biological organisms.

ATP

Adenosine triphosphate; the body's energy currency.

Metabolism

The process by which your body converts food and drink into energy for you to live and function.

Substrate-level phosphorylation

A method of forming ATP by directly transferring a phosphate group to ADP from another molecule.

Anaerobic Energy Systems

Energy systems that produce energy without the need for oxygen.

Glycolysis

The breakdown of glucose to produce energy.

Krebs Cycle

A cycle that processes Acetyl-CoA to produce NADH and FADH2, which are used in the electron transport chain.

Electron Transport Chain (ETC)

A series of protein complexes in the mitochondrial membrane that drive oxidative phosphorylation to produce ATP.

Rate-limiting enzyme

An enzyme that regulates the speed of a metabolic pathway, and its activity is influenced by the concentration of substrates and products.

Free Energy

The portion of energy in a system available for work, such as muscle contraction.
