NADP-linked dehydrogenase catalyzes _________
(a) Glucose 6-phosphate+NADP^+ ↔ 6-phosphogluconate + NADPH + H^+
(b) Lactate + NAD^+ ↔ pyruvate + NADH + H^+
(c) Pyruvate + CoA + NAD^+ ↔ acetyl-CoA + CO2 + NADH + H^+
(d) L-Malate + NAD^+ ↔ oxaloacetate + NADH + H^+
I have been asked this question in an online interview.
The query is from Electron-Transfer reactions in Mitochondria topic in chapter Oxidative Phosphorylation and Photophosphorylation of Biochemistry
