Question

_____ are the most diverse molecules in the cell.

• A. Carbohydrates
• B. Lipids
• C. Proteins
• D. Vitamins and Minerals

Answer 1

The correct option is C Proteins

Proteins show enormous diversity because of different proportions and combinations of twenty-one amino acids within the protein molecule. A large number of permutations and combinations of these amino acids are responsible for the almost unlimited variety of proteins. Proteins are the most abundant and most varied of the macromolecules having one or more polypeptides (chains of amino acids). The proteins constitute almost 50% of the total dry weight of the cell.
Carbohydrates, lipids, vitamins and minerals are not as diverse as proteins.
