Question

I think its 1 and 5. Correct? I was also wondering you could maybe help me see if I am on the right thinking for this question. So we would use NAD+ and NADH + H+ because they are coenzymes that go from oxidation to reduction which is what happened in the reaction? So is the reaction went the other way would you still use NAD+ and NADH + H+ or would you use FAD and FADH2? Help would be much appreciated!

identify the statements that aocurately desorbe how hydrogen ion ooncentration relates to energy production oxidatve phosphorytation. Energy is generated as a result of the dnemenoe in hydrogen ion conoentrason between the intermembrane space and the oplasm. Hydrogen ions enter the minochondria matrix via faciitated dinusion (tacliated lamport). ATPsymease provides energy inthe form of ATPtoactively transport H* into the Hydrogen ion concentration lower inthe mitochondria mairiehanin intermembrane The pH in the intermembrane space is higher than the pHinthe mitochondral matrix Oxidative phosphorylaton relies on the hydrogen ion oonoentraton gradent generated bythe electron Iransporlchain.

Explanation / Answer

Answer is 2,4 & 6

1. Incorrect because H+ concentration difference is between intermembrane space and matrix

3. Incorrect becauseATP synthase does not provide energy for H+ transfer. It produces energy due to the H+ ion transfer into matrix

5. Incorrect because pH in intermembrane space is higher (less acidic) in matrix than intermembrane space.

NADH2 and FADH2 undergo oxidation to release free electrons which are picked up by the free oxygen atom to from water.
