Question

Mention the important series of events of aerobic respiration that occur in the matrix of the mitochondrion and in the inner membrane of the mitochondrion.

Answer 1

Aerobic respiration takes place during the following events:

As pyruvate oxidizes completely in mitochondria, it is converted to pyruvate. As each hydrogen atom is removed one by one, oxidation occurs. Three molecules of carbon dioxide remain when all hydrogen atoms are removed.

During mitochondrial respiration, this event occurs on the inner membrane. A hydrogen atom loses its electrons, and the electrons are transferred to molecular oxygen in an atom exchange process. Adenosine triphosphate is synthesised simultaneously.
