Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The structure of biomolecules is closely related to the functions they perform in living cells. Which statement below best illustrates this concept?
A
Lipids may be saturated or unsaturated.
B
Carbohydrates such as starch are long chains of sugar monomers.
C
The active site of a protein enzyme precisely fits the shape of its substrate molecules.
D
Proteins may be made up of chains that are folded or coiled.
Explanation: 

Detailed explanation-1: -Enzymes Are Powerful and Highly Specific Catalysts This is the case for the large and very important class of proteins called enzymes.

Detailed explanation-2: -Enzymes are proteins comprised of amino acids linked together in one or more polypeptide chains. This sequence of amino acids in a polypeptide chain is called the primary structure. This, in turn, determines the three-dimensional structure of the enzyme, including the shape of the active site.

Detailed explanation-3: -Proteins are essential components of organisms. It participates in almost every process within cells. It is involved in the processes of DNA replication, cell signaling, catalyzing metabolic reactions, construction of cell and tissue structures, and transportation of molecules from one place to another.
