10 protein and enzyme facts:
1-proteins are made from long chains of smaller molecules called aminio acids.
2-these long chains are folded into particular shapes.
3- enzymes are biological catalysts.
4-enzymes are also proteins.
5- if the spape of the enzyme chnages it is said to be denatured.It may no longer work.
6-Proteins are polymers.
7-proteins are built up cells when monomers called amino acids join together end to end.
8- A lot of amino acid molocules = a protein molecule
9-glycine and alaninine are examples of amino acids.
10- long chains of amino acids fold to give each type of protein molecule a specific shape. e.g. strucular compenonets of tissues (musles), hormones (insulin), antibodies (part of bodies immune syestem) and biological catalys (enzymes). the particulr shape that a protein molocule has aloows other molocules to fit into it. this is pariticalay important for antibodes and enzymes.
how do enzymes work?
-ENZYMES ARE BIOLOGICAL CATALYS. biological catylsts are substances that icrease the rate of chemical reactions without being used up.
-substrate- a subastance on which enzymes act.
-enymes:proteins folded into complex shapes that aloow smaller molecules to fit into them.
-active site: the place where substrate molecules fit in.
- if the shape of an enzyme changes its active site may no longer work.a.k.a. denatured.
-sunstances can also be denatured by high temps or high PH levels.
