Abiologist would most likely study all of the chemical activities of an organism to obtain information about the organism's:
a) number of mutations
b) reproductive cycle
c) development
d) metabolism

The correct answer is option - D. metabolism.

Explanation:

Metabolism is the total chemical reaction that sustains or maintains the life in a biological system, organism or cell. Metabolism can be two types on the basis of the products they made by forming or breaking of molecules. Catabolism is the process that includes the breaking of large macromolecules into smaller units by the chemical reaction and anabolism is the chemical reaction that involves the synthesizing the macromolecules by smaller units.

Metabolism is the process that involves or generates energy in these chemical reactions. Conversion of energy from food for cellular processes.

Thus, the correct answer is option D. metabolism.

many other transport proteins, often called pumps, move materials against a concentration gradient. active transport drives molecules across a membrane from a region of lower concentration to a region of higher concentration. this process, shown in figure 5.1, uses transport proteins powered by chemi- cal energy.
