Question

Which of the following statement is correct about glycolysis?

• A. In this process, glucose undergoes complete oxidation to form two molecules of pyruvic acid.
• B. In aerobic organisms, it is the only process in respiration.
• C. The fructose 1, 6-bisphosphate is split into dihydroxyacetone phosphate and 3-phosphoglyceraldehyde (PGAL).
• D. In plants, this glucose is derived from sucrose, which is the end product of photosynthesis, or from structural carbohydrates like starch.

Answer 1

Answer: (C)

In glycolysis, glucose undergoes partial oxidation to form two molecules of pyruvic acid. In plants, this glucose is derived from sucrose, which is the end product of photosynthesis, or from storage carbohydrates like starch. In anaerobic organisms, it is the only process in respiration.
