ATP Production Overview

Question 1

Adenosine Triphosphate (ATP)

Answer 1

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

Question 2

Aerobic

Answer 2

A process requiring oxygen

Question 3

Anaerobic

Answer 3

A process in which oxygen is absent

Question 4

Cellular Respiration

Answer 4

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

Question 5

Electron Transport System

Answer 5

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.

Question 6

Glycolysis

Answer 6

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.

Question 7

Krebs Cycle

Answer 7

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