Enzymes Flashcards
1
Q
Role of enzymes
A
Speed up a reaction , biological catalyst
2
Q
What need to happen for the reaction to be catalysed
A
The reacting chemical (substrate) must bind toghether with the active site of the enzyme
3
Q
Effect of temp on enzyme activity
A
As temp increases so does rate of reaction however once the temperature is past optimum , rate of reaction decreases .
4
Q
Effect of PH on enzyme activity
A
Each enzyme works best at a specific PH value .
Changes in PH effect shape of enzymes active site .
5
Q
Effect of substrate concentration on enzyme activity
A
As substrate concentration increases so does enzyme activity .
6
Q
What happens when an optimum substrate concentration is reached
A
A point will come where no more substrate can fit .
