question 4
the starting compound (initial reactant) for glycolysis is:
glucose
fatty acid
a, b, and c
a and b only
pyruvate

Explanation:

Glycolysis is the metabolic pathway that breaks down glucose. Glucose is the starting compound. Fatty acids are involved in lipid metabolism (like beta - oxidation), not glycolysis. Pyruvate is the end - product of glycolysis (when oxygen is sufficient, it enters the citric acid cycle; under anaerobic conditions, it can be further metabolized in fermentation). Since only glucose is the starting compound for glycolysis among the options.

Answer:

glucose
