What kind of enzyme inhibition occurs when an inhibitor is covalently bonded to the enzyme?

• Irreversible

• Competitive

• Non-Competitive

• Lazy Inhibition

What kind of enzyme inhibition happens when the inhibitor bonded to the active site can be removed if the substrate concentration is high?

• Irreversible

• Non-Competitive

• High-Concentration

• Competitive

What kind of enzyme inhibition happens when an inhibitor binds to the allosteric site, changing the shape of the enzyme not allowing any other substrates to bind

• Competitive

• Non-Competitive

• Irreversible

• Spy Inhibition

Draw what a lock and key model of an enzyme is:

1. 1. Before the substrate binds

2. 2. After the substrate binds

A(n) _______ ___ model represents the fact that some enzymes change the shape of their active site in order to receive the substrate perfectly.

If the ΔG is positive, that must mean the reaction is:

• Endergonic

• Exergonic

• Catabolic

• Anabolic

If the ΔG is negative, that means the reaction is:

• Anabolic

• Catabolic

• Endergonic

• Exergonic
