List three properties of enzymes
...

What may happen to the active site if the temperature is too high and why?
What role does the active site play in enzyme reactions?
What is activation energy?
Name the two hypotheses on enzyme mechanisms
...

10) Any excess of either acid or base causes denaturing of enzymes(protein)
...

- Most are globular proteins and are coded for by DNA
...

- They are required in small amounts
...

- Does not alter the nature or properties of the end products of the reaction
...

-Speed up the rate of reaction without themselves being used up or permanently altered
...

(any 3 relevant points are accepted)
2) Cleft or depression n the surface of an enzyme molecule to which a substrate molecule
attaches in order for a reaction to take place
...

4) It is the attachment of the substrate molecule to the enzymes
...

6) Lock and key hypothesis and induced fit hypothesis
...

8) pH2, pH 7
...
The pH for these two enzymes differs because both the enzymes need to
work in two different environments with different pH ranges
...

10) Ionic bonds
