Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Enzymes are..
A
lipids
B
carbohydrates
C
proteins
D
nucleic acids
Explanation: 

Detailed explanation-1: -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-2: -Although an enzyme generally consists of protein, a few enzymes contain non-protein components such as nucleic acid. The ribozyme discovered by Thomas Cech and others in 1986 is a catalyst made of RNA, which acts on itself and cleaves RNA.

Detailed explanation-3: -Enzymes are proteins, and they make a biochemical reaction more likely to proceed by lowering the activation energy of the reaction, thereby making these reactions proceed thousands or even millions of times faster than they would without a catalyst.

Detailed explanation-4: -All enzymes are proteins, but the reverse is not true. So, the correct answer is “Option B”. Note: Enzymes are not the only biological catalysts that’s found in our body.
