All the enzymes that participate in the citric acid cycle are located in the mitochondrial matrix, except for which enzyme?   1. aconitase   2. succinate dehydrogenase   3. fumarase   4. malate dehydrogenase

Choose all the enzymes or enzyme systems of the citric acid cycle that could be classified as oxidoreductases. (Select all that apply.) succinate dehydrogenase aconitase isocitrate dehydrogenase α-ketoglutarate dehydrogenase complex citrate synthase fumarase malate dehydrogenase

Please explain the Krebs Cycle how you understand it. Explanation The Krebs cycle is most often referred to as the TCA cycle or the citric acid cycle. During this cycle, a multitude of metabolic events take place in the mitochondrial matrix, which is involved in cellular respiration during aerobic respiration. During this cycle, glucose and other molecules are broken down into ATP , therefore the cell's energy currency, and carbon dioxide are created. To create ATP, the Krebs cycle produces NADH and FADH2 that are necessary in the process stage of cellular respiration known as the electron transport chain. An enzyme called acetyl CoA is applied in the Krebs cycle, which provides ATP and carbon dioxide. Question: Please respond to the explanation post above on Krebs cycle.

1) In aerobic conditions in animal cells, oxidative decarboxyliation release CO2 by eliminating the methyl (—CH3) group. : True / False 2) All enzymes of the cycle are located in the cytoplasm, except succinate dehydrogenase, which is bound to the inner mitochondrial membrane: True / False 3) Malonate is a competitive inhibitor of the enzyme succinate dehydrogenase. In the presence of malonate, one would expect succinate to accumulate: True / False

The citric acid cycle is shown. The methyl carbon in acetyl CoA is labeled with C14C14 (shown in red). Identify which of the carbons in each intermediate will be labeled in the first round of the cycle by selecting the indicated carbon(s). Each question has multiple options, answering with only one option is incorrect.  Which carbon(s) in α‑ketoglutarate will contain C14? 1 2 3 4 5 Which carbon(s) in succinyl‑CoA will contain C14? 1 2 3 4 Which carbon(s) in succinate will contain C14? 1 2 3 4 Which carbon(s) in fumarate will contain C14? 1 2 3 4 Which carbon(s) in malate will contain C14? 1 2 3 4 Which carbon(s) in oxaloacetate will contain C14? 1 2 3 4
