Vedclass · Answer

(B) In aerobic respiration,one molecule of acetyl $	ext{CoA}$ ($2$-carbon compound) enters the Krebs cycle ($TCA$ cycle).During the Krebs cycle,decarboxylation occurs at two specific steps:$1$. Conversion of isocitrate to $\alpha$-ketoglutarate (catalyzed by isocitrate dehydrogenase).$2$. Conversion of $\alpha$-ketoglutarate to succinyl $	ext{CoA}$ (catalyzed by $\alpha$-ketoglutarate dehydrogenase).Each of these steps releases one molecule of $	ext{CO}_2$.Therefore,a total of $2$ decarboxylation events occur during the complete oxidation of one molecule of acetyl $	ext{CoA}$.

How many times does decarboxylation take place during the complete oxidation of one molecule of acetyl $\text{CoA}$ in aerobic respiration?
