Question

which substance is produced as a by - product of both glycolysis and aerobic respiration?
glucose
acetyl coa
nadh
atp

Explanation:

Glycolysis breaks down glucose to produce ATP and NADH. Aerobic respiration further processes the products of glycolysis and also generates ATP. Glucose is the starting - material, not a by - product. Acetyl CoA is an intermediate in aerobic respiration but not a by - product of both processes in the same sense as ATP. NADH is produced in glycolysis but its role and production in aerobic respiration are different from being a common by - product. ATP is produced as a by - product in both glycolysis (substrate - level phosphorylation) and aerobic respiration (oxidative phosphorylation).

Answer:

D. ATP
