The correct answer is B - ATP
Cellular respiration is the process by which cell produce energy in form of ATP for functioning.
It occurs in three stages :
1. Glycolysis - takes place in the cytoplasm where a molecule of glucose is broken down to form pyruvate.
2. Krebs cycle - takes place in the mitochondria in which co -enzymes NADH and FADH are produced, and some ATP molecules.
3. Electron transport chain - takes place in the mitochondria in which the highest number of ATP molecules, at least 34, are generated.
