Question

1.in this phase of cellular respiration, glucose is completely broken down into carbon dioxide gas, some ATP is produced, and many molecules of NADH and some FADH2 are produced.

		glucose breakdown
		oxidative phosphorylation

2.

1. In this phase of cellular respiration, NADH and FADH2 are used to power the electron transport chain, which in turn creates the conditions needed for the ATP synthase enzyme to make ATP.

   		glucose breakdown
   		oxidative phosphorylation

Answer 1

glucose is oxidized via glycolysis, pyruvate oxidation and TCA cycle during these process many NADH molecules are produced, ( NAD+ is reduced to NADH) and some ATP and some FADH2 are produced.

NADH and FADH2 produced via break down of glucose is oxidized via electron transport chain, NADH and FADH2 is oxidized to NAD+ and FAD+ respectively and using the energy of electrons H+ from the matrix is pumped to intermembrane space and generates and H+ gradient, the energy of H+ gradient is used to make ATP from ADP and Pi via ATP synthase located in the inner mitochondrial membrane, this is called oxidative phosphorylation.

1) glucose breakdown

2) oxidative phosphorylation,.
