Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of the following statements is true about metabolism?
A
It involves the process that break down small molecules in the body
B
It involves the process that break down large molecules in the body
C
It involves all the processes that break down and build up molecules in the body
D
It involves the processes that build up large molecules in the body
Explanation: 

Detailed explanation-1: -Which of these statements is true about metabolism? Explanation: Metabolic pathways can be both circular and linear in nature. Due to metabolism, all biomolecules have a turnover and their levels are not constant. All metabolic reactions are catalyzed.

Detailed explanation-2: -Catabolism (pronounced: kuh-TAB-uh-liz-um), or destructive metabolism, is the process that produces the energy needed for all activity in the cells.

Detailed explanation-3: -The answer choice that best defines metabolism is (B). Metabolism is the sum of the chemical reactions that occur in each cell of an organism.

Detailed explanation-4: -Your metabolism involves two processes, catabolism, and anabolism. These two processes are carefully balanced to help you stay healthy: Catabolism is the process of breaking down food into simpler forms, releasing energy. Anabolism is the process of using this energy to build and repair cells in your body.
