binds to a different part of the enzyme

Answer 6

NON-COMPETITIVE INHIBITOR

Question 7

permanently deactivates the enzyme

Answer 7

IRREVERSIBLE INHIBITOR

Question 8

is a molecule that slows down a reaction by taking the place of the real substance at the enzyme’s working site.

Answer 8

Competitive Inhibition

Question 9

is a molecule that slows down a reaction by attaching to a different part of the enzyme, changing its shape so it can’t work properly.

Answer 9

Non-competitive Inhibitor
