Question

Assertion (A) All enzymes are proteins but all proteins are not enzymes.

Reason (R) Enzymes are biocatalysts and have a stable configuration having an active site.

• A. Both A and R are correct but R is the correct explanation for A
• B. Both A and R are correct but R is not the correct explanation for A
• C. A is correct but R is not correct
• D. A is incorrect but R is correct.

Answer 1

The correct option is B

Both A and R are correct but R is not the correct explanation for A

The correct option is B

Statement:

1. Enzymes are proteins made up of amino acids that help reduce reactive activation energy.
2. Only a few proteins, with the help of their active sites, have the ability to bind the substrate in a way that allows the reaction to take place efficiently.
3. As mentioned above all enzymes are proteins but not all proteins are enzymes.

Reason:

1. Enzymes are known to accelerate the rate of reaction in living cells and hence they are known as biocatalysts.
2. Enzymes usually have an active site where substrates can bind.
3. The compound is called an enzyme/substrate complex that has a very stable configuration.

Final Answer: The statement is given here and the reason is both true.
