Question

which carbohydrate can be used by the body as an immediate source of energy?
glucose
cellulase
chitin
glycogen

Explanation:

Glucose is a simple sugar that can be readily metabolized by cells through processes like glycolysis to produce ATP (adenosine triphosphate), which is the energy currency of the cell. It can be directly used as an immediate energy source. Cellulose is a structural carbohydrate in plant cell walls and humans lack the enzymes to digest it for energy. Chitin is a structural polysaccharide found in the exoskeletons of arthropods and cell walls of fungi and is not an energy source for the human body. Glycogen is a storage form of glucose in animals (stored in liver and muscles). While glycogen can be broken down to release glucose, it is not the immediate source like glucose itself.

Answer:

glucose
