How many NADPH 2 and ATP molecules are produced in a single TCA cycle?

Options

A3 and 1 respectively
B2 and 1 respectively
C0 and 1 respectively
D3 and 2 respectively

Correct answer

C. 0 and 1 respectively

Step-by-step solution

Tricarboxylic acid cycle or Krebs cycle occurs in the mitochondrial matrix. In this acetyl CoA combines with oxaloacetic acid in a series of reactions to regenerate oxaloacetic acid. In this cycle 3 N A D H 2 , 1 F A D H 2, and 1ATP are formed. N A D P H 2 is not formed in the Kreb's cycle.
