Enzymes Flashcards
1
Q
What do biological catalysts do?
A
Increase the rate of a chemical reaction by lowering the energy input of the reaction
2
Q
What are enzymes made of?
A
They are made of proteins and are produced by all living cells
3
Q
Factors affecting enzyme activity??
A
Temperature and pH
4
Q
What is degradation?
A
The breakdown of enzymes
5
Q
What is synthesis?
A
The build up of enzymes
6
Q
What is the optimum temperature?
A
This is the temperature where the enzyme works best
7
Q
Enzymes can only react with one substrate because?
A
The active site is complementary to its substrate
8
Q
Enzymes have a range of pH values that they can work at, what is this called?
A
The working range
9
Q
What happens at temperatures above 40 degrees?
A
The enzyme becomes denatured and they lose their shape and the reaction will stop
