**Transcription and Explanation for Educational Website:** **Diagram Explanation:** The diagram illustrates the Citric Acid Cycle, also known as the Krebs Cycle, which is a key metabolic pathway that oxidizes Acetyl CoA to produce energy in the form of ATP. Significant intermediates and processes in the cycle include: - Initiation with Acetyl CoA combining with Oxaloacetate to form Citrate. - Sequential transformation into Isocitrate, then α-Ketoglutarate, and Succinyl CoA. - Release of CO₂ molecules during the transformation from Isocitrate to α-Ketoglutarate and from α-Ketoglutarate to Succinyl CoA. - Regeneration of Oxaloacetate from Malate. - Energy carrier molecules NADH, FADH₂, and ATP are produced throughout the cycle. **Question:** "For each molecule of glucose (C₆H₁₂O₆) oxidized by cellular respiration, how many moles of CO₂ are released in the citric acid cycle? (see the figure above)" **Options:** a. 2 b. 4 c. 6 d. 0 e. 3 --- The correct answer involves considering the cycle's operation per glucose molecule, as each glucose results in two turns of the citric acid cycle.
