The function of coenzyme A is to facilitate oxidative phosphorylation.

Text Solution

AI Generated Solution

The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding Coenzyme A's Role**: Coenzyme A (CoA) is a crucial molecule in cellular respiration, particularly in the metabolic pathways that break down carbohydrates and fats. Its primary function is to assist in the conversion of pyruvate into acetyl-CoA. 2. **Formation of Acetyl-CoA**: After glycolysis, pyruvate is produced. Coenzyme A reacts with pyruvate to form acetyl-CoA, a two-carbon molecule. This reaction also releases carbon dioxide (CO2) as a byproduct. 3. **Entry into the Krebs Cycle**: The acetyl-CoA produced then enters the Krebs cycle (also known as the citric acid cycle). In this cycle, acetyl-CoA combines with oxaloacetic acid to continue the process of cellular respiration. 4. **Krebs Cycle Products**: During the Krebs cycle, several important molecules are produced, including NADH, FADH2, and ATP. These molecules are essential for the next stage of respiration, which is oxidative phosphorylation. 5. **Oxidative Phosphorylation**: While NADH and FADH2 produced in the Krebs cycle are used in oxidative phosphorylation to generate ATP, Coenzyme A itself does not facilitate this process. Instead, it plays a role in preparing the substrates (like acetyl-CoA) that enter the Krebs cycle. 6. **Conclusion**: Therefore, the statement that "the function of coenzyme A is to facilitate oxidative phosphorylation" is false. Coenzyme A is primarily involved in the formation of acetyl-CoA and the Krebs cycle, not directly in oxidative phosphorylation. **Final Answer**: False ---
