Question

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

Explanation:

Glucose is the simplest form of carbohydrate (monosaccharide) and can be directly used by cells for energy production through processes like cellular respiration. Glycogen is a storage form of glucose in animals, chitin is found in the exoskeletons of arthropods and cell walls of fungi, and cellulose is a structural polysaccharide in plant cell walls. Humans lack the enzymes to break down cellulose and chitin for energy, and glycogen needs to be broken down into glucose first.

Answer:

glucose
