Key Concepts

Functions of Carbohydrates

Carbohydrates serve several essential functions in cells, including energy storage, providing structural support, and acting as raw materials for synthesis. They are crucial for cellular metabolism, where they can be broken down to release energy. Additionally, carbohydrates play a role in cell recognition and signaling, contributing to cell identity.

Energy Storage

Carbohydrates, particularly in the form of glycogen in animals and starch in plants, are vital for energy storage. When energy is needed, these polysaccharides can be hydrolyzed into glucose, which is then utilized in cellular respiration to produce ATP, the energy currency of the cell. This process ensures that cells have a readily available energy source.

Structural Role of Carbohydrates

In addition to energy storage, carbohydrates contribute to the structural integrity of cells. For example, cellulose in plant cell walls provides rigidity and strength, while chitin serves a similar function in the exoskeletons of arthropods. These structural carbohydrates are essential for maintaining the shape and stability of cells and tissues.
