enzymes

Question 2

structure of enzymes

Answer 2

all enzymes are globular proteins
soluble in water due to presence of many hydrophilic side groups on their amino acids
only small part is involved in catalysis- active site

Question 3

induced fit

Answer 3

active site isnt complementary to substrate
active site changes shape as the substrate binds
this stresses and distorts the bonds

Question 4

factors affecting enzymes

Answer 4

temperature
pH
enzyme concentration
substrate concentration

Question 5

inhibiter

Answer 5

similar shape to the substrate and is complementary tk the active site
binds to active site
reduces the number of enzyme substrate complexes which can form

Question 6

non competitive inhibitors

Answer 6

attach to the enzyme at a site other than the active site
they change shape of the active site by changing the tertiary structure of the enzyme
the active site and substrate are no lomger complementary so less substrate can bind

Question 7

reducing the effect of inhibitors

Answer 7

the effects of a competitive inhibitor can be reduced by increasing the substrate concentration
more substrate would successfully bind to the active site than inhibitor and therefore reducing the effect of the inhibition
the max rate of reaction or a level very close to the max rate of reaction can be reached

Question 8

reducing a non competitive inhibitor

Answer 8

increasing the substrate concentration cant prevent the inhibitor from binding to the enzyme
the max rate of reaction will always be lower in the presence of a non competitive inhibitor
