When two molecules of acetyl CoA enter the TCA cycle, net gain at the end of the cycle is

Options

A. `2NADH_(2) + 2FADH_(2) + 1GTP`
B. `3NADH_(2) + 2FADH_(2) + 2GTP`
C. `6NADH_(2) + 2FADH_(2) +2GTP`
D. `3NADH_(2) +1FADH_(2) + 4GTP`

Answer

C

Explanation

Krebs' cycle produces 2 GTP (or 2 ATP) through substrate level phosphorylation. Six molecules of `NADH_(2)` and 2 molecules of `FADH_(2)` for every two molecules of Acetyl CoA oxidised by it.
