From which of these phases of cellular respiration does the cell get the most ATP?
A) glycolysis
B) citric acid cycle
C) transition reaction
D) electron transport chain

Question

Quizplus · Accepted Answer

The electron transport chain generates the most ATP, producing a total of 28-34 ATP molecules per glucose molecule oxidized. In contrast, glycolysis only produces 2 ATP molecules per glucose and the citric acid cycle only produces 2 ATP molecules per glucose. The transition reaction produces only 2 ATP molecules per glucose as well. Therefore, the best choice is D as it is the phase where the most ATP is generated.
