each NADH molecule fed into the electron transport chain produces how many ATP?

Question

what a molecule that moves electrons from the citric acid cycle to the electron transport chain.? is it any of these choices...pyruvic acid, CO2, ADP, NADH, H20...idk..

Answer 1

1. Each NADH is responsible for 3 ATP.

Here's a quote from the website listed below: "The number of protons pumped out as electrons drop from NADH through the respiratory chain to oxygen is theoretically large enough to generate, as they return through ATP synthase, 3 ATPs per electron pair (but only 2 ATPs for each pair donated by FADH2)."

2. In the citric acid cycle, electrons are taken to the electron transport chain on NADH and FADH2.

Answer 2

(1)3 acetyl coA (2) (3) c) 6 (4)2 oxidative phosphorylation in cellular respiration (5)a) 4 (6)4 mitochondrial intermembrane space (7)3 reduction of pyruvate to form lactate
