Terms to Know
Adenosine Triphosphate (ATP)

The primary form of energy used by cells to perform work; it is the nucleotide adenine (A) with three phosphate groups instead of one.

Aerobic

A process requiring oxygen.

Anaerobic

A process in which oxygen is absent.

Cellular Respiration

The process of converting molecules, such as proteins, lipids, and carbohydrates, into cellular energy.

Electron Transport System

A series of reactions that couple electron donors with electron acceptors with the end result of transferring H⁺ ions across cell membranes to generate ATP.

Glycolysis

The first step in cellular respiration; the process of breaking down glucose into pyruvate that takes place in the cytoplasm of cells; is an anaerobic process.

Krebs Cycle

A series of chemical reactions used to generate energy, aerobically, from the pyruvate generated by glycolysis and catabolism of carbohydrates, proteins, and lipids.
