CELL RESPIRATION

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Most of the ATP is synthesized during the ____ stage of cellular respiration
A
Krebs cycle
B
Glycolysis
C
Fermentation
D
Electron Transport Chain
Explanation: 

Detailed explanation-1: -So, the correct answer is ‘Krebs cycle’.

Detailed explanation-2: -The stage that produces most of the ATP during cellular respiration is the electron transport system (ETS). The inner mitochondrial membrane holds the ATPase enzyme and the complexes for ETS.

Detailed explanation-3: -The electron transport chain produces most of the ATP generated during cellular respiration. The electron transport chain can produce over 30 molecules of ATP for each glucose molecule broken down. This is in contrast to glycolysis and the citric acid cycle, which each only net about two ATP molecules.

Detailed explanation-4: -Oxidative Phosphorylation This process generates most of the ATP we use-up to 27 for each molecule of glucose.

Detailed explanation-5: -The electron transport chain is located on the inner membrane of the mitochondria. The electron transport cycle yields around 30-32 ATP molecules, according to current studies.
