biological catalysts that speed up reactions made of protein
1 of 12
How do enzymes work?
The substrate of the reaction fits into the active site of the enzyme. Once it is in place the enzyme and the substrate bind together and the reaction then rapidly takes place and the products are released from the surface of the enzyme.

what happens if the temperature increases?
so does the rate of the reaction
3 of 12
what is a catalyst?
a substance that speeds up a chemical reaction without being changed itself
4 of 12
what is a protein molecule made up of?
long chains of small units called amino acids
5 of 12
what are proteins used for in the body? (4 details)
structurual components such as muscles and tendons, hormones such as insulin, antibodies which destory pathogens, catalysts in the form of enzymes.
6 of 12
what happens to the substrate when it leaves the active site?
splits into products
7 of 12
what happens to the enzyme after the product has left the active site?
it can be used again
8 of 12
what is the optimum?
all enzymes work best at only one particular temperature and ph
9 of 12
what temperature do the reactions that take place in living cells happen at?
relatively low
10 of 12
what temperature do the enzymes start to denature at?
40 degrees
11 of 12
what happens when an enzyme denatures?
the active site structure has changed
