What are the primary functions of carbohydrates in biomolecules?

Carbohydrates are one of the essential biomolecules that serve several vital functions in living organisms:

• Energy Source: Carbohydrates are the primary source of energy. Glucose, a simple sugar, is broken down during cellular respiration to release energy.
• Structural Component: Some carbohydrates like cellulose in plants provide structural support to cell walls.
• Storage Molecule: Carbohydrates such as starch in plants and glycogen in animals act as storage forms of energy.
• Metabolic Intermediates: Carbohydrates are involved in various metabolic pathways, serving as intermediates for different biochemical reactions.
