enzyme action

Question 1

non competitive inhibitors

Answer 1

binds to enzyme at point other than active site - alters shape of active site so substates can no longer occupy it. an increase in substrate conc doesn’t have an effect bc inhibitor is not competing for the same site

Question 1

competitive inhibitors

Answer 1

bind to enzyme at active site - competes w substrate for available active sites, eventually all substrates will bind, conc of inhibitor determines how long this will take/effect on enzyme activity

Question 2

end product inhibition

Answer 2

keeps conc of chemical relatively constant - end product inhibits first enzyme at beginning of metabolic pathway - if conc of end product is too high, more inhibition (usually non competitive).
