ATP molecules, which are used for energy by cells, are built during all three stages of cellular respiration. Which stage of cellular respiration generates the most ATP molecules?


The Krebs cycle

Glycolysis

The electron transport chain

Fermentation

Verified Answer :

C.) "The electron transport chain" generates the most ATP molecules

In short, Your Answer would be Option C

Hope this helps!

Answer:

The correct answer will be option-The electron transport chain.

Explanation:

Adenosine triphosphate or ATP is the energy molecule formed inside the cell by the aerobic oxidation of the food material. This oxidation of the food material is known as the aerobic respiration which takes place in four stages
.

The four stages of cellular respiration are glycolysis (the breakdown of glucose), pyruvate decarboxylation, Krebs cycle and electron transport chain. Each stage of aerobic respiration forms the energy molecules either in the form of ATP or reducing equivalents NADH and FADH₂.

The energy equivalents are reduced in the electron transport chain to provide protons which help in the formation of the ATP molecules. Because of these equivalents, a large number of ATP molecules (24) are formed in the electron transport chain.  

Thus, option-The electron transport chain is the correct answer.
