Concept explainers
Interpretation:
In citric acid cycle, the enzyme having a name that indicates the reverse reaction has to be identified.
Concept Introduction:
Protein catabolism: It is defined as breakdown of proteins into smaller units that is into amino acids. These amino acids get transported finally
Citric Acid Cycle: It involves 8 series reaction which converts acetyl group present in acetyl coenzyme A into 2
Substrate: The molecule where the reaction takes place with help of enzymes.
Enzyme: The proteins that helps
Oxidation: The oxidation is reaction that involves addition of oxygen atom or loss of electrons or removal of hydrogen atom present in the chemical compound.
Reduction: It involves removal of oxygen or addition of hydrogen to the chemical compound.
Coenzyme: They are non-proteins molecules which helps enzymes for catalyzing the reaction.

- Why are so many different enzymes needed?arrow_forwardTo learn more about the role of the electron transport chain in generating energy during respiration in this organism, you use two drugs. These drugs can each pick up electrons from specific intermediates in the pathway as shown above. You treat cells carrying out respiration with either a saturating dose of drug A or B, so that all the electrons which would normally continue along the pathway are captured by the drug in question. Complete the following table. In the presence of drug A, will the rate of ATP synthesis increase, decrease, or stay the same? Explain your reasoning. In the presence of drug B, will the rate of ATP synthesis increase, decrease, or stay the same? Explain your reasoning.arrow_forwardATP Synthase in plants has the same basic structure and function as the ATP Synthase in humans. O True O Falsearrow_forward
- NADH and FADH2 can "create" ATP only if the cell can do electron transport True Falsearrow_forwardWhat are the three kinds of enzymes-controlled reaction so that the chemical bond energy from a certain nutrietiens is released to the cell in a form of ATP?arrow_forwardWhat is the function of the enzyme succinate dehydrogenase?arrow_forward
- Chemistry What is the main aspect that the enzymes succinyl-CoA synthetase, pyruvate kinase, and phosphoglycerate kinase have in common?arrow_forwardwhat is the definition of energy from a metabolic perspective?arrow_forwardWhy are some metabolic reactions coupled to the hydrolysis of ATP? To drive the nonspontaneous reaction To extend the half-life of enzymes To increase the equilibrium constant To bypass metabolic regulationarrow_forward
- At what point in photosynthesis is the proton motive force generated? in the light harvesting complex of photosystem I| as electrons are passed to the enzyme NADP+ reductase as electrons move between photosystem II and photosystem I in the Calvin cycle O as electrons are passed to the primary electron acceptorarrow_forwardDraw one reaction from glycolysis that is a redox reaction. Name the enzyme, show all cofactors, and indicate the oxidizing agent and the reducing agentarrow_forwardPut the following substances in the correct order in which they are first encountered in the common metabolic pathway: succinate, FeSP, CO2, FADH2.arrow_forward
