Question

Catalytic power of an enzyme depends on
A. Km constant
B. Turn Over Number
C. Quaternary structure
D. Both A and B​

Answer 1

Answer:

Option D (Both A and B)

Explanation:

Catalytic power of an enzyme depends on mainly two things

1. Turn Over Number- It is the number of substrate molecules which converted into product per unit time by a molecule of an enzyme.

•Catalytix power is directly proportional to turn over number.

$Catalytic \: Power \propto \: Turn \: Over \: Number$

•Carbonic anhydrase is considered as the fastest enzyme.

Here are some turn over numbers of some important enzymes

a. Carbonic anhydrase => 360 lakh/min.

b. Catalase => 50 lakh/min

c. Lysozyme => 30 per minute.

2. Km Constant- It is the concentration of substrate at which rate

of reaction attains half of its maximum velocity.

$Km \: Constant = \frac{Vmaximum}{2}$

• This term was coined by M.Menten.

Answer 2

$\huge\bf{Answer}$

Catalytic power of an enzyme depends on Km per constant and also Turn Over Number.

The answer is option(D.) Both A and B

• (A) Turn Over Number:-

Changing of number of Substrate molecules total number of changing as per the according to the time take by this the enzyme of the molecule.

• (B) Km Constant:-

This Km per Constant means checking of substrate for calucating of rate.

$\bf{Additional-information :-}$

Catalysts have a huge role in the manufacture of industrially important chemicals, because their use increases the speed of the reaction, which in many ways brings economic benefits and accelerates production.

Therefore, a lot of money and human labor is engaged in research in the field of catalysis.

When the speed of a chemical reaction increases with the mere presence of a substance, it is called catalysis.

The substance whose presence increases the reaction speed is called catalyst.

The catalyst does not participate in the reaction, only affects the speed of the action.
