Carbohydrates play a crucial role in both energy storage and structural integrity in living organisms. They are a primary source of energy, as they can be broken down to release glucose, which is utilized by cells for metabolic processes. Additionally, carbohydrates are pivotal in providing structure, particularly in the form of polysaccharides such as cellulose in plants, which contributes to the rigidity of cell walls. This structural function allows plants to maintain their shape and resist external pressures. Thus, carbohydrates are vital not only for immediate energy needs but also for ensuring the overall structural framework of various organisms.
