Assume you begin with four cycles of the Krebs cycle. How many molecules of ATP are produced?

A. 42
B. 36
C. 48
D. 8
E. 60
F. None of these

Answer :

Final answer:

In cellular respiration, the Krebs cycle and oxidative phosphorylation produce ATP. Each round of the Krebs cycle can generate approximately 10 ATP molecules.

Explanation:

In cellular respiration, ATP is produced through a series of metabolic pathways, including the Krebs cycle and oxidative phosphorylation. The Krebs cycle, also known as the citric acid cycle, takes place in the mitochondria and generates energy-rich molecules such as NADH and FADH2.

These molecules then enter the electron transport chain, where they donate electrons to a series of protein complexes. As electrons pass through the protein complexes, energy is released and used to pump protons across the inner mitochondrial membrane. The resulting proton gradient drives the synthesis of ATP through a process called oxidative phosphorylation.

Each NADH molecule can produce approximately 2.5 ATP molecules, while each FADH2 molecule can produce approximately 1.5 ATP molecules. Therefore, the total ATP production from one round of the Krebs cycle is approximately 10 ATP molecules.
