Answer:
D. All of the above
Explanation:
The term metabolism is used to describe the various chemical reactions in the body that meet the structural and energy needs of a living being. Among the purposes of these chemical reactions, we can mention the synthesis and breakdown of biomolecules, energy production and the conversion of nutrient molecules into macromolecule precursor units.
There are many factors that alter metabolism: age, genetics, gender, weight, height, level of physical activity. In addition, some bodily functions can also interfere with metabolism such as calorie burning, food digestion and circulating blood.
