Carbohydrates normally function in animal as the functional units of lipids enzymes in the regulation of metabolic processes a component of triglycerides energy storage molecules. a b. c. d.

Explanation / Answer

13-C (The structure of suger consist of nucletide,deoxyribose suger and phosphate group),the answer is wrong because in option it is written as ribose suger.

14-D(The structure of suger consist of nucletide,deoxyribose suger and phosphate group)

15-B(in the nucleotide of rna bases of thymine is replaced with uracil)

16-d(carbohydrate is the molecule which give energy to the body,carbohydrtate after metabolism converts in glucose which provides instant energy to cells and left out carbohydrte is used for storage purpose)
