Botany - Respiration in Plants Question with Solution | TestHub

Kreb's cycle is the aerobic process of respiration occurring in the mitochondria which helps in releasing stored energy via oxidation of acetyl-CoA. Other than helping in obtaining energy, this cycle also generates precursors to certain amino acids. One of the steps in the cycle is the formation of fumaric acid from succinic acid by oxidation process catalyzed by succinate dehydrogenase enzyme. During this step, FAD is reduced to${\mathrm{F}\mathrm{A}\mathrm{D}\mathrm{H}}_2$which later participates in the electron transport system to generate ATP. In the step of oxidative decarboxylation of alpha- ketoglutarate to succinyl$\mathrm{C}\mathrm{o}\mathrm{A},\mathrm{ }{\mathrm{N}\mathrm{A}\mathrm{D}\mathrm{H}}_2$is formed.
