Which statement about reaction shown below is CORRECT?   Group of answer choicesThis reaction is the final step of the Krebs cycle and occurs in the mitochondrial inter membrane space.This dehydrogenation reaction is coupled to the oxidation of NAD+ to NADH.In the forward direction, a hydroxyl undergoes a dehydration reaction to form a ketone.This unfavourable reaction (under standard conditions) is driven in part by the highly exergonic hydrolysis of a thioester in the next step.

The Krebs cycle produces ATP:Group of answer choicesindirectly via NADH and FADH2; and indirectly via GTPdirectly via ADP phosphorylationindirectly via NADH and FADH2directly via ADP phosphorylation; and indirectly via NADH and FADH2

The Krebs cycle still operates, even though the concentration of oxaloacetate in the mitochondrial matrix is low. Because:Group of answer choicesAcetyl-CoA is a negative allosteric modulator of the PDH complexthe hydrolysis of a thioester bond is highly favourableThe interconversion of L-malate and oxaloacetate is readily reversibleThe ΔG’0 for the formation of oxaloacetate from L-malate is large and positive

A single "turn" of the Krebs cycle will yieldMultiple Choice1 ATP, 2 NADH, and 1 FADH2.2 ATP, 2 NADH, and 2 FADH2.1 ATP, 3 NADH, and 1 FADH2.2 ATP, 3 NADH, and 2 FADH2.1 ATP, 2 NADH, and 2 FADH2.
