Answer to Problem 1RQ

Solution:

Main source of energy for the body.

Explanation of Solution

Carbohydrate molecules only contain carbon, oxygen and hydrogen atoms in specific ratios. The primary function of carbohydrates is to provide energy to the body. Most of the carbohydrates before entering the bloodstreams are converted into glucose which is taken by cells in the body and utilized in producing ATP molecules. It involves series of complex processes called cellular respiration. ATP provides energy which is used by cells for number of metabolic processes.

Thus, carbohydrates are the main source of energy storage for the body.

Conclusion

Carbohydrates are the main source of energy for the body.
