Vedclass · Answer

(B) The Krebs cycle (also known as the Citric Acid Cycle or $TCA$ cycle) occurs in the mitochondrial matrix.During this process,the acetyl group of acetyl-CoA (derived from pyruvic acid) is completely oxidized.The carbon atoms of the acetyl group are released as $CO_2$,and the hydrogen atoms are transferred to electron carriers ($NAD^+$ and $FAD$) to form $NADH$ and $FADH_2$.Ultimately,the pyruvic acid derivatives are broken down into $CO_2$ and $H_2O$ (as the final products of aerobic respiration including the electron transport chain).Therefore,option $B$ is the most accurate description of the overall metabolic outcome.
