- The large amount of energy used during aerobic exercise(e.g., running) requires large amounts of oxaloacetate.Explain why acetyl-CoA cannot be used to produceoxaloacetate in this circumstance. What is the sourceof oxaloacetate molecules during aerobic activity?For each Acetyl CoA that enters the Krebs Cycle and the products goes through the ETC creates____ATP. ( Explain well with proper step by step and type The answer.)If ox als acctate, the molecule that starts with Acetyl- CoA in the citric at id cych, is not avalible it affects glycolysis, fatty acid oxidation electron transport and oxidative phosphorylation. Explain can affect steps both in front and behind in cellular respiration. why this Step

The calculation should be based on the total number of protons and c-subunits of 2-Acetyl-CoA that has 15 subunits.In beta-oxidation, which cofactor is required the for second oxidation reaction (conversion of beta-hydroxyacyl-CoA to beta-ketoacyl-CoA)? NAD+ water FAD CoA-SHSkeletal muscle cannot synthesize fatty acids, yet it producesthe enzyme acetyl-CoA carboxylase. Explain the role of thisenzyme
- Coenzyme A (CoA-SH) plays an important role in the Pyruvate Dehydrogenase Complex reaction. Which is correct? Coenzyme A serves as an electron acceptor in this reaction. The hydrolysis of a CoA thioester has a positive AG", the hydrolysis is endergonic and unfavorable. Coenzyme A is derived from thiamine, a vitamin. Coenzyme A contains -SH group and can serve as an acyl group carrier.Lactic acid is a biproduct formed at the end of anaerobic respiration. This molecule is dangerous to cells of the body if it builds up too much. Despite this, the formation of lactic acid is very important. Explain why the process of anaerobic respiration is so important (providing reference to glycolysis, the role of coenzymes, and ATP formation).Which of the following statements is TRUE about fatty acid biosynthesis? Citrate carries malonyl CoA to the cytosol. O Acetyl ACP is the donor of the acetyl group. O NADPH is used as the reducing equivalent in the process.
