Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which process produces the most ATP per molecule of glucose?
A
lactic acid fermentation
B
aerobic respiration
C
alcoholic fermentation
D
all are about the same
Explanation: 

Detailed explanation-1: -The metabolic cycle that provides the highest net ATP per glucose molecule is oxidative phosphorylation .

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 majority of ATP synthesis occurs in cellular respiration within the mitochondrial matrix: generating approximately thirty-two ATP molecules per molecule of glucose that is oxidized.

Detailed explanation-4: -Aerobic respiration is much more efficient, and produces ATP much more quickly, than anaerobic respiration. This is because oxygen is an excellent electron acceptor for the chemical reactions involved in generating ATP.

Detailed explanation-5: -In aerobic respiration, the full oxidation of one glucose molecule can theoretically yield 38 ATP molecules.
