Question

Nomenclature of enzymes is done on the basics of
(a) The substrate on which they act
(b) Type of reactions they catalyze
(c) End products formed
(d) Both A and B

Answer 1

Enzymes catalyze transferases, hydrolases, lyases, and various other reactions and these reactions give end products, and based upon this an enzyme is named.

Complete answer:
The proteins or amino acids catalyze any biochemical reactions and help the reaction to carry out faster than the normal rate and it just helps to increase the rate of reaction and does not react with the compounds in the reaction. They are called enzymes. Thousands of enzymes have been discovered, separated, and studied. Most of these enzymes have been classified into different groups based on the type of reaction they catalyze and they are named based on the substrate they act and the type of reaction they catalyze.

Additional Information: - An enzyme, like any protein, has a secondary and tertiary structure.
- Enzyme catalysts differ from catalysts of inorganic molecules in many ways.
- Generally, enzymes get damaged at high temperatures but inorganic catalysts work efficiently at high temperatures and high pressures.
- Enzymes are divided into 6 subclasses each with 4-13 subclasses and designated accordingly by a four-digit number.
- The 6 classes of enzymes are oxidoreductases or dehydrogenases, transferases, hydrolases, lyases, isomerases, ligases.
- This classification provides a four-digit code to identify individual enzymes
So, the correct answer is ‘both A and B’.

Note: For example, glucose-6-phosphotransferase has the enzyme code 2.7.1.2. The first digit of the code indicates the major class of the enzymes, while the second digit and the third digits indicate the sub-class and sub-subclass respectively. The last digit of the code is the serial number of the enzyme in a particular subclass.
