Question

if 3 molecules of ribosome are converted to pyruvate, how many ATP and NADH will be formed

Answer 1

Most of the ATP is generated by the proton gradient that develops across the inner mitochondrial membrane. 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).

the net production for the conversion of one mol of glucose to pyruvate is thus 2 mols of ATP and 2 mols of NADH. This is the net energy yield of glycolysis under aerobic conditions.

As we have 3 molecules of ribosome converting to pyruvate thus

6mol of ATP and 6 mol of NADH
