Answer #1

Answer - A GLUCOSE MOLECULE

A GLUCOSE MOLECULE - 36 or 38 ATP molecule

NADH molecule produce - 3ATP molecule

Six CO2 molecule - Six CO2 molecule join and form glucose. It uses or invest the energy.

TWO PYRUVIC ACID MODECULES -

ATP calculation for 1 Pyruvic Acid

From 1 pyruvate to acetyl coA it produce 1NADH. Then Acetyl coA enter to TCA and forms 3NADH and 1FADH2

Total ATP for ONE PYRUVIC ACID = 4NADH X 3 ATP = 12 ATP

                                                          1FADH2 X 2 ATP = 2 ATP

Total ATP from ONE PYRUVIC ACID = 14 ATP

Total ATP from TWO PYRUVIC ACID = 28 ATP
