Final answer:
The product of the Embden-Meyerhof pathway (glycolysis) is pyruvate. Acetyl-CoA, FADH2, and GTP are not products of glycolysis but are associated with subsequent stages of cellular respiration such as the citric acid cycle.
Step-by-step explanation:
The Embden-Meyerhof pathway, commonly known as glycolysis, is a ten-step metabolic pathway that converts glucose into pyruvate, which is then typically used in the citric acid cycle to produce more energy. During this process, several products are formed, but specifically, the end product is pyruvate. The answer to the student's question is thus (a) Pyruvate. Acetyl-CoA, FADH2, and GTP are not products of glycolysis. Acetyl-CoA is a product of the oxidation of pyruvate, which occurs after glycolysis. FADH2 is a molecule that is produced in the citric acid cycle, and GTP is also formed in the citric acid cycle, specifically during the conversion of succinyl-CoA to succinate. Glycolysis instead produces ATP and NADH as forms of energy currency used by the cell.
