The largest number of ATP molecules is produced in which phase of cellular respiration?

A) glycolysis
B) preparation reaction
C) citric acid cycle
D) electron transport chain
E) Calvin cycle

Electron Transport Chain

a component of the electron transport system involved in cellular respiration that generates a proton gradient to produce ATP.

ATP Molecules

Adenosine triphosphate molecules, which are the primary energy carriers in all living organisms, providing energy for most cellular processes.

Cellular Respiration

The process by which cells produce energy from carbohydrates; oxygen is consumed as a reactant along with the organic fuel.
