Solution

The correct option is A Both activation and inhibition
The allosteric site of an enzyme is where a molecule that is not a substrate may bind to either enhance or reduce the enzyme activity. Binding of an allosteric regulator changes the shape of the enzyme and influencing its overall activity
So, the correct answer is 'Both activation and inhibition'

Q. Allosteric inhibitors do not compete for the active sites in enzymes. Why?

Q. When drugs attach to allosteric sites on enzymes, the shapes of active sites radically are affected so that the substrate molecules cannot recognise the active sites.

Q. Inhibitor binds to the active site of enzyme in inhibition while it binds to allosteric site of an enzyme in inhibition.

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