Question

In Krebs' cycle, the hydrogen of malate is accepted by

• A. $FAD$
• B. $NAD$
• C. $FMN$
• D. $CoA$

Answer 1

Answer: (B)

$NAD$

Answer 2

In Krebs' cycle malate is dehydrogenated or oxidised through the agency of malate dehydrogenase to produce oxaloacetate Hydrogen is accepted by $NAD^+$. Malate $+\underset{\text{(H-acceptor)}}{ {NAD(P)+}} {<=>[\text{Malate}][\text{dehydrogenase}]}$ Oxalate $+ NADH + H^+$
