Which of the following statements best describes the structure and function of a carbohydrate?

a. carbohydrates are made up of starchy monomers and are used for structure, protection, and reproduction.
b. carbohydrates are made up of sucrose molecules that are important for transportation and protein synthesis.
c. carbohydrates are large molecules made up of monosaccharides and are used by organisms for energy storage.
d. carbohydrates are long, winding molecules made up of amino acids and are important in the synthesis of fats and hormones.

The correct answer is C. Carbohydrates are large molecules made up of monosaccharides and are used by organisms for energy storage.

Carbohydrates are the large group of organic compounds, which are comprised of Carbon, hydrogen, and Oxygen. They mainly include simple sugar (like glucose, fructose) and starch ( present in food like potato, grains).

They are the most essential and readily available source of energy for all life forms.

Complex carbohydrates ( polysaccharides) like starch are made up of simple sugar called monosaccharide ( like glucose).

Thus, option C) is the right answer.
