ENZYMES AND METABOLISM

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Enzymes must be proteins because ____
A
they must be able to constantly build themselves with obscure amino acids as they grow
B
they must be able to break into products
C
they must be able to make triglyceride
D
they must allow for complicated or varying shapes to attach
Explanation: 

Detailed explanation-1: -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-2: -The shape of the enzyme active site allows another molecule to fit like a “lock and key” or “puzzle pieces”. This molecule is the substrate and is specific to the enzyme it fits into.

Detailed explanation-3: -The induced change in the shape of the enzyme molecules in such a way that it is fit for the substrate enzyme interaction. The change in the shape of the enzyme molecule can put a strain on the substrate and this stress may help in bonds breaking, thus promoting the reaction.

Detailed explanation-4: -An enzyme’s function depends on its three-dimensional shape. An enzyme is a biocatalyst that is composed of protein or ribonucleic acid (RNA). An enzyme increases the rate of a biochemical reaction by lowering the level of activation energy that is required in the reaction.
