Enzyme Inhibitors

Question 1

enzyme inhibitors

Answer 1

• enzyme activity can be prevents

- molecules that bind to the enzyme that they inhibit

Question 2

competitive inhibitors

Answer 2

• molecules that have a similar shape to that of substrate molecules
• compete with the substrate molecules to bind to the active site
• no reaction takes place
• block active site so no substrate molecules can fit in it

Question 3

high concentration of inhibitor

Answer 3

-take up nearly all of the active sites but hardly any substrate will get to the enzyme

Question 4

high concentration of substrate

Answer 4

-substrates chances of getting to an active site before inhibitor increases

Question 5

non-competitive inhibitors

Answer 5

• bind to enzyme away from active site

- causes active site to change shape so substrate molecules can no longer bind to it
