Question

Which of the following is a catabolic reaction?

• A. Intercellular digestion
• B. Intracellular digestion
• C. Respiration
• D. All of the above

Answer 1

The correct option is D All of the above

The catabolic processes are the reactions in which the large complex molecules are broken down to form the smaller molecules. The process is an exergonic process in which the energy is released due to the breaking of the bonds of the larger complex molecules. Intracellular digestion refers to the breaking of the larger molecules. Intercellular digestion is the processes in which the molecules are broken down outside the cell and then absorbed. During internal respiration, there is the breakdown of the molecules to produce ATP.

Thus, the correct answer is option D.
