The carbohydrates are made up of polysaccharides, which are made up of monosaccharides. The monosaccharides combine together to form polysaccharides. The common monosaccharide found plants and animals is glucose.

The one of primary function of carbohydrate is to provide the energy to our body. The carbohydrates in our food before entering into blood, break down into sugar which is glucose.

Glucose inter into blood stream and produce ATP which are energy packets. The glucose is break down in cellular respiration which may be aerobic or anaerobic.

For many metabolic processes ATP provide the energy.

In plant the major energy source is starch.
