Interpretation:
Whether any step of citric acid cycle directly produces
Concept Introduction:
Citric Acid Cycle: It involves 8 series reaction which converts acetyl group present in acetyl coenzyme A into 2
Enzyme: The proteins that helps
Condensation Reaction: It involves combination of two small molecules to form larger molecule with elimination of small molecule.
Rearrangement Reaction: It involves change in the carbon chain of the molecule that results to give structural isomer.
Oxidative Decarboxylation: It involves removal of carboxylate group that results in release of carbon dioxide.
Phosphorylation: It involves transfer of phosphate group from inorganic/organic phosphate to another chemical compound.
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.
Hydration: The combination of substance with water is termed as hydration.

- why is the citric acid cycle is located in close cellular proximity to the electron transport chain?arrow_forwardIf ATP synthase completely stopped working, could glycolysis or the citric acid cycle still produce any ATP? Explain.arrow_forwardAlthough molecular oxygen (O2) does not participate directly in any of the reactions of the citric acid cycle, the cycle operates only when O2 is present. Explain this observation.arrow_forward
- a) Describe the three irreversible reactions of the Citric Acid Cycle. Ensure to indicate their purpose/role, the substrates and products, the enzyme involved, and any significant features of the reaction. b) Why are these reactions considered irreversible (why can't they be reversed)? c) Using one of the reactions as an example, explain why it is important for the cell that the reaction is irreversible.arrow_forwardWhich reactions of the citric acid cycle transfer energy as FADH2?arrow_forwardWhat citric acid cycle intermediate would be regenerated?arrow_forward
- What molecules areproduced as a result of the citric acid cycle?arrow_forwardDiscuss the assertion that the Citric acid cycle is central for metabolism.arrow_forwardWhich reaction in the citric acid cycle is most analogous to the oxidative decarboxylation of 6- phosphogluconate to ribulose 5-phosphate? What kind of enzymebound intermediate is formed in both reactions?arrow_forward
