lecture 13 part 3

Question 1

what happens when temp drops to rxn rate

Answer 1

fewer substrates have energy to overcome Ea rxn barrier to become products so rxn rates slow

Question 2

higher temps =

Answer 2

denaturation

Question 3

higher pH impacts rxn rates how

Answer 3

increases rxn rate

Question 4

environmental factors affect conformation of active site can impact what

Answer 4

enzyme activity

Question 5

structural changes that affect complimentary fit between active sites and substrates can speed/slow rxn

Answer 5

slow

Question 6

competitive inhibitors

Answer 6

interfere with active site of enzyme so substrate cannot bind

Question 7

noncompetitive inhibitors

Answer 7

change the shape of the enzyme so it cannot bind to substrate

Question 8

turnover #

Answer 8

of rxns per unit of time by one enzyme moelcule

Question 9

Vmax

Answer 9

max rate of an enzymatic rxn in terms of amount of product made (or substances used) per unit of time by all enzyme moleqs in rxn
