Question

9. Which step causes activation of catalytic site of an enzyme?
A)Change in pH of the surroundings.
B)Formation of Enzyme Substrate complex.
C)Change in the charge of the active site.
D) Change in temperature​

Answer 1

Answer:

B)Formation of Enzyme Substrate complex is the step causes activation of catalytic site of an enzyme.

Answer 2

The step that causes the activation of the catalytic site of an enzyme is B). Formation of Enzyme Substrate Complex.

• Enzymes help minimize the total amount of activation energy required by the complex molecules.
• Every enzyme has a unique site called the 'active site'. It is here that the substrate binds to the enzyme.
• After binding, the enzyme along with the substrate together is known as the Enzyme Substrate Complex.
• From this step, the catalytic site gets activated in the enzyme.
• Due to the activation of this catalytic site, the enzyme successfully releases the products required for the reaction to take place.
• And once again the enzyme becomes free to bind with another substrate.

Hence, the correct answer will be The step that causes the activation of the catalytic site of an enzyme is B). Formation of Enzyme Substrate Complex.
