B) Peptide
D) Water
The catalytic cycle of an enzyme action can be described in the following steps.
Arrange them in sequence accordingly:
The binding of the substrate induces the enzyme to alter its shape, fitting more tightly
around the substrate
The substrate binds to the active site of the enzyme, fitting into the active site
The enzyme releases the products of the reaction and the free enzyme is mondty to him to
another molecules of the substrate and run through the catalytic cycle once again
The active site of the enzyme, now in close proximity of the substrate breaks the chemical
bonds of the substrate and the new enzyme product complex is formed
A 2 3 4
B) 2-1 4-3
C) 1-2-4-3
D)2-1-3-4

Answer:
Arrange the steps of catalytic action of an enzyme in order and choose the right option.
(i) Enzyme releases products of reaction and the enzyme is free to bind to another substrate.
(ii) Active site of enzyme is in close proximity of substrate and breaks the chemical bonds of substrate.
(iii) Binding of substrate induces enzyme to alter its shape fitting more tightly around substrate.
(iv) Substrate binds to active site of enzyme fitting into active site.
ANSWER
iv) Part of enzyme where substrate molecules gets attached is known as active site. On attachment it forms enzyme substrate complex.
iii) Induced-fit model stated that when the substrate comes in contact with the active site, the active site modulates according to the shape of the substrate to form a enzyme substrate complex.
ii) Active site of enzyme is in close proximity of substrate and breaks the chemical bonds of substrate.
i) Enzyme releases products of reaction and the enzyme is free to bind to another substrate.
So, the correct answer is option A.
