enzymes Flashcards
1
Q
what is the role of a buffer
A
to keep ph constant
2
Q
What happens to an enzyme if the temperature is too low
A
not enough kinetic energy
not enough collisions
not enough ESC forming
no breaking down of substrate into products
3
Q
what happens to enzyme activity if the temperature is too high
A
enzyme begins to denature
bonds are broken
tertiary structure changes –> shape of active site changes
substrate is no longer complimentary
time taken for it to break down increases
4
Q
how do inorganic ions work
A
ion binds to the enzyme
ESC can form more easily
charge distribution can be affected
speed up the rate of reaction
