C3.5 Factors affecting enzyme action Flashcards
1
Q
what factors affect enzyme action
A
temp and pH
2
Q
how does temp increase enzyme action
A
substrate and enzyme are moving fast so there are more collisions per second
3
Q
what happens if temp is too high
A
enzyme molecule vibrate and shape of active site changes meaning substrate no longer fits into active site- DENATURED
4
Q
What happens if an enzyme becomes denatured
A
enzyme can no longer catalyse the reaction
5
Q
what is the ideal temp for an enzyme
A
37 degrees (body temp)
6
Q
what happens if conditions for enzymes are too acidic or alkaline
A
active site denatures
