Which of the Following Pathways Converge to a Common Catabolic

Question

Which of the following pathways converge to a common catabolic pathway?
A) only the pathways for the catabolism of carbohydrates and lipids
B) only the pathways for the catabolism of carbohydrates and proteins
C) only the pathways for the catabolism of lipids and proteins
D) the pathways for the catabolism of proteins, carbohydrates, and lipids

Accepted Answer

The pathways for the catabolism of proteins, carbohydrates, and lipids all converge to a common catabolic pathway called cellular respiration. During cellular respiration, glucose, fatty acids, and amino acids are all broken down to produce ATP, which the cell can use for energy. Therefore, option D is the correct answer.
