Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Where in the cell does aerobic respiration take place?
A
Nucleus
B
Cytoplasm
C
Mitochondria
D
Cell membrane
Explanation: 

Detailed explanation-1: -While most aerobic respiration (with oxygen) takes place in the cell’s mitochondria, and anaerobic respiration (without oxygen) takes place within the cell’s cytoplasm.

Detailed explanation-2: -Answer and Explanation: In the mitochondria, cellular respiration occurs in the mitochondrial matrix through the Krebs cycle to form ATP, FADH2 and NADH.

Detailed explanation-3: -Here, oxygen acts as an electron acceptor. The ATP molecules produced as a result of this process are used to produce energy. Mitochondria are the site of aerobic respiration. It is a membrane-bound organelle found in all cells except red blood cells.

Detailed explanation-4: -Mitochondria are double membrane bound cytoplasmic organelles present in most eukaryotic cells. They are responsible for aerobic respiration, producing energy for the cell, which they achieve through oxidative phosphorylation.

Detailed explanation-5: -In the cell, Aerobic respiration occurs within the mitochondria, and the anaerobic respiration occurs within the cytoplasm of a cell.
