In competitive inhibition

An example of competitive inhibition is

In competitive inhibition the

Blocking enzyme action through blocking its active sites is (a) Allosteric inhibition (b) Feedback inhibition (c) Competitive inhibition (d) Non-competitive inhibition

Statement 1- Competitive inhibitor is also called as substrate analogue. Statement 2- It resembles the enzyme in structure.

Assertion (A): Competitive inhibitors compete with natural substrate for their attachment on the active sites of enzymes. Reason (R) : In competitive inhibition, inhibitor binds to the allosteric site of the enzyme.

An example of competitive inhibition of an enzyme is the inhibition of :

Non-competitive inhibition often results in

Assertion (A) : Non-competitive inhibitor inhibits the catalytic activity of enzyme by binding with its active site. Reason (R): Non-competitive inhibitor changes the shape of the active site in such a way that substrate can't recognise it

What is the role of competitive inhibitor during enzyme action? (a) It enhances enzyme action (b) It declines enzyme action (c) It alters the active site of the enzyme and prevents the binding of substrate (d) it inhibits breaking of chemical bond of the substrate
