Final answer:
Pyruvate is not considered a high energy molecule like ATP or NADH, as it is not directly involved in their production during cellular respiration.
Step-by-step explanation:
Pyruvate is not considered a high energy molecule like ATP or NADH. While pyruvate is a product of the glycolysis process and plays a key role in cellular respiration, it is not directly involved in the production of ATP or NADH.
During glycolysis, glucose is broken down into two molecules of pyruvate, and in the process, it generates a small amount of ATP and NADH. However, the main production of ATP and NADH occurs during the later stages of cellular respiration, specifically in the citric acid cycle and oxidative phosphorylation.
In summary, pyruvate is an important molecule in cellular respiration, but it is not considered a high energy molecule like ATP or NADH.
