Question

Where does aerobic respiration (cellular respiration) take place?

Answer 1

Aerobic respiration takes place in the mitochondria of eukaryotic cells and involves several stages including glycolysis, transformation of pyruvate, the Krebs cycle, and oxidative phosphorylation. It is a process by which cells break down glucose and oxygen to produce carbon dioxide, water, and ATP.

Step-by-step explanation:

Aerobic respiration, also known as cellular respiration, takes place in the mitochondria of eukaryotic cells.

It is a process by which living cells break down glucose and oxygen to produce carbon dioxide, water, and ATP (adenosine triphosphate).

The process of aerobic respiration involves several stages:

1. Glycolysis: This occurs in the cytosol of the cell and does not require oxygen.
2. Transformation of Pyruvate: In the presence of oxygen, pyruvate enters the mitochondria to proceed into the Krebs cycle.
3. Krebs Cycle: The Krebs cycle takes place in the matrix of the mitochondria and involves the transfer of energy from pyruvate to two energy carriers, NADH and FADH₂.
4. Oxidative Phosphorylation: This final stage of aerobic respiration occurs in the inner membrane of the mitochondrion, where electrons extracted from food move down the electron transport chain, ultimately producing ATP.
