Inhibition Types Quiz

Which of the following best describes competitive inhibition?

• The inhibitor binds to the enzyme-substrate complex.

• The inhibitor binds to a site other than the active site.

• The inhibitor competes with the substrate for the active site.

• The inhibitor permanently inactivates the enzyme.

In non-competitive inhibition, the inhibitor:

• Binds to the active site.

• Binds to the enzyme-substrate complex.

• Binds to a site other than the active site, altering enzyme function.

• Increases the enzyme's activity.

Which type of inhibition can be overcome by increasing substrate concentration?

• Competitive inhibition

• Non-competitive inhibition

• Uncompetitive inhibition

• Irreversible inhibition

Uncompetitive inhibition occurs when the inhibitor:

• Binds only to the free enzyme.

• Binds only to the enzyme-substrate complex.

• Binds to either the free enzyme or the enzyme-substrate complex.

• Binds to a site other than the active site.

Which type of inhibition typically results in a decrease in V(_{max})?

• Competitive inhibition

• Non-competitive inhibition

• Uncompetitive inhibition

• Mixed inhibition

Which of the following is an example of irreversible inhibition?

• A molecule that binds temporarily to the active site.

• A molecule that forms a covalent bond with the enzyme.

• A molecule that binds to the enzyme-substrate complex.

• A molecule that binds to an allosteric site.

Reversible inhibition usually involve _______ interaction between inhibitor and enzyme.
