Out of 36 ATP molecules produced per glucose molecule during respiration

Options

A. 2 are produced outside glycolysis and 34 during respiratory chain
B. 2 are produced outside mitochondria and 34 inside mitochondria
C. 2 during glycolysis and 34 during Krebs' cycle
D. all are formed inside mitochondria

Answer

B

Explanation

A total of 38 ATP molecules are produced per glucose molecules during respiration . Out of which 2 ATP are produced outside mitochondria.
(i.e., glucoysis in cytoplasm) and 36 ATP inside mitochondria (i.e., ATP through respiratory chain.) In contrast , in some cells the number of ATP produced inside mitochondria equals to 34 and thus, there is a net synthesis of 36 ATP molecules.
