Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
In what cell organelle does Cellular Respiration occur?
A
Mitochondrion
B
Chloroplast
C
Lysosome
D
Endoplasmic reticulum
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: -Summary. Mitochondria are organelles whose membranes are specialized for aerobic respiration. The matrix of the mitochondria is the site of Krebs Cycle reactions. The electron transport chain and most ATP synthesis rely on the compartments created by the inner membrane of the mitochondria.

Detailed explanation-3: -In the mitochondria, cellular respiration occurs in the mitochondrial matrix through the Krebs cycle to form ATP, FADH2 and NADH. The formed FADH2 and NADH then go into the inner mitochondrial membrane where they are involved in the electron transport chain to form more ATP molecules.
