Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
An enzyme is a ____
A
Carbohydrate
B
Lipid
C
Nucleic Acid
D
Protein
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: -Only few proteins have the capability to bind the substrate with the help of their active sites in such a manner that allows the reaction to take place in an efficient manner. Hence, all enzymes are proteins but all proteins are not enzymes.

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: -Trypsin: These enzymes break proteins down into amino acids in the small intestine. Lactase: Lactase breaks lactose, the sugar in milk, into glucose and galactose.

Detailed explanation-5: -Protease (made in the pancreas; breaks down proteins)
