- BCATylysts .
3What are Biological catylyts ?
- Athe same as catlyts
- BThe enzymes that speeds up reactions in our cells
4How many types does Enzymes come in ? Name them and explain each.
- A2 types, Creators and breaker, creators create breakers break
- B2 types
Builders(small molecule join to build larger ones. Help to build important molecules in our cells .)
Breakers(break large molecules into smaller ones. Important in digestion where large foods are broken into small ones which our bodies can use)
5What are the substances called that enzymes work on ?
- Asubtrates
- Bsubtances
6Where does reactions takes place ?

- Ain the cells
- Bin blood.
11What is the fastest enzyme known ?
- Acatalase
- Bcatylysts enzyme
12Why does catalase works so quickly ?
- ABecause if it builds up, it can become poisonous .
- B it i found in living cells,
13How many properties does enzymes have ? List them .
- A5.

- BAn enzyme that breaks down protein . works best in 37C & 8 PH
20At high temperatures, the proteins breaks down, what effect does this have on the enzyme ?
- AActive site is change & subtrate no longer fits.
- Bsubtrate changes shapes
