The final pathway of aerobic respiration is:

A. glycolysis
B. the transition reaction
C. the citric acid cycle
D. the electron transport chain



Answer :

Final answer:

The final pathway of aerobic respiration is the electron transport chain, which transfers electrons from NADH and FADH₂ to oxygen to generate ATP. Glycolysis, the citric acid (Krebs) cycle, and oxidative phosphorylation are key steps in this process.


Explanation:

The final pathway of aerobic respiration is the electron transport chain. This process involves the transfer of electrons from NADH and FADH₂ to oxygen through a series of redox reactions, eventually generating ATP by oxidative phosphorylation.

In glycolysis, a six-carbon glucose molecule is partially broken down into two three-carbon molecules of pyruvate, producing 2NADH + 2H* and 2 net ATP. The citric acid (Krebs) cycle then completely breaks down pyruvates from glycolysis into CO₂ and H₂O molecules, generating additional ATP.

During the electron transport chain, electrons are passed rapidly from one component to the next, reducing molecular oxygen and producing water. This stage, along with chemiosmosis, leads to the production of numerous ATP molecules as the final step of aerobic respiration.
