Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Metabolism is ____
A
a constant supply of energy from food
B
an increase of entropy in an organism
C
all the energy transformation reactions in an organism
D
biochemical pathways involved in synthesis of macromolecules
Explanation: 

Detailed explanation-1: -metabolism, the sum of the chemical reactions that take place within each cell of a living organism and that provide energy for vital processes and for synthesizing new organic material.

Detailed explanation-2: -By definition, an organism’s metabolism describes all of the different chemical reactions that take place within the organism. These reactions can be anabolic, building up complex molecules from simple ones. They can also be catabolic, breaking down complex molecules to release energy.

Detailed explanation-3: -Metabolism (pronounced: meh-TAB-uh-liz-um) is the chemical reactions in the body’s cells that change food into energy. Our bodies need this energy to do everything from moving to thinking to growing. Specific proteins in the body control the chemical reactions of metabolism.

Detailed explanation-4: -Metabolism is made of both catabolic (breakdown) and anabolic (build-up) reactions. The processes of making and breaking down sugar molecules are two examples of metabolic pathways.

Detailed explanation-5: -Metabolism consists of all of the energy transformation and chemical reactions that occur in an organism. is true for every organism.
