Catalysts And Enzymes Flashcards
1
Q
What do catalysts do?
A
Catalysts increase the rate of chemical reactions with out chemically changing themselves.
2
Q
What are enzymes?
A
Enzymes are biological catalysts and are proteins.
3
Q
What do enzymes do?
A
Enzymes catalyse specific reactions in the body. This is due to the size of their active site.
4
Q
Factors that effect enzyme reaction
A
Enzyme activity is affected by temperature and pH.
5
Q
What effect does temperature have on enzymes?
A
High temperature denatures the enzyme, changing the dhape of the active site.
6
Q
What effect does pH have on enzymes?
A
pH can affect the shape of the active site and make it work very efficiently or stop it working.
