|
how many reactions go on in living things all the time |
thousands |
|
|
what are enzymes |
enzymes are proteins used to speed up chemical reactions |
|
|
where are the instructions for making enzymes found |
in genes |
|
|
how do enzymes work and what the process is called |
every enzyme has an active site which is where a substrate goes into the active site. this can only happen to some substrates as each enzyme will only speed up one reaction as the substrate has to be the correct fit for the enzyme. once this happens products are produced which are the leftovers of the substrate. the process is called a lock and key model |
|
|
what is a active site |
a hole in the enzyme where a substrate connects to for a reaction |
|
|
what is a substrate |
substrate is a molecule that is changed in a reaction |
|
|
what is a product |
what is produced from the reaction |
|
|
what is it called when an enzyme is working at its best |
optimum |
|
|
what happens if the enzyme gets to hot |
bonds of the enzyme break. this changes the shape of the active site which stops the substrate from working. denaturing the enzyme |
|
|
what happened if you change the ph of a enzyme |
the bonds bigger to brake and the active site changes which denatures the enzyme. |
