main function of carbohydrates

Answer 36

store and provide energy

Question 37

Carbohydrates are broken down into smaller glucose units, which can be easily absorbed by the cells.

Question 38

When glucose is further broken down, the energy is released from the chemical bonds. The energy is then used or stored by the body.
