1
New cards

what are the two types of enzyme inhibition

competetive

non competetive

2
New cards

what dk inhibitors do

reduce the rate of reaction

3
New cards

what is competitive inhibition

competetive inhibitors have a similar shape to the substrate though can vary in size

must have a complimentary shape

they bind to the active site and form an enzyme inhibitor complex

it blocks the substrate from entering the by blocking the active site reducing the number of es complexes

however if substrate concentration is increased they can outcompete the inhibitor and bind

4
New cards

what is non competitive inhibition

do not compete with the substrate for the active site

attatch away from the active site at the allosteric site and distort the tertiary shape of the enzyme which leads to a change in the active site

this means the substrate no longer fits so no es complexes can form which decreases the rate of reaction

increasing substrate concentration will not increase the rate of reaction
