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

UP CPMTUP CPMT 2015Respiration in Plants

Solution:

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)^+} \xrightleftharpoons[\text{dehydrogenase}]{\text{Malate}}$ Oxalate $+ NADH + H^+$
