What is the net ATP obtained from 1 cytoplasmic NADH when it is oxidized by the electron-transport chain, using the glycerol 3-phosphate shuttle?
A) 2.5
B) 1.5
C) 2.0
D) 1.0
E) None of the above.

Question

Quizplus · Accepted Answer

The glycerol 3-phosphate shuttle moves electrons from cytoplasmic NADH to FADH2, which enters the electron transport chain at a lower energy level. This means that each cytoplasmic NADH only results in the generation of 1.5 ATP, rather than the usual 2.5 ATP from mitochondrial NADH. Therefore, the net ATP obtained from 1 cytoplasmic NADH with the glycerol 3-phosphate shuttle is 1.5.
