Factors affecting Enzymes

HideShow resource information
1. Temperature - The optimum temperature for enzymes in the body is...
37 oc
1 of 10
Below this temp, the rate of reaction drops as...
the molecules have less kinetic energy
2 of 10
Above 40 oc, the enzzymes begin to denature and this...
changes the active site so that it is no longer coplimentary to id's substrate
3 of 10
This change is then...
permanent
4 of 10
In normal conditions, the enzyme and substrate parrticles move faster...
as the teemperature increases, making them more likely to collide with enough energy to react
5 of 10
2. pH - Enzymes are affected within a very small...
range of pH, usually denaturing with 3-4
6 of 10
Once denatured, the change...
is permanent
7 of 10
The shape of enzymes is due to the forces between the different parts of...
the protein molecule which hold the folded chains in place
8 of 10
A change in pH affects these forces and changes...
the shape of the molecule, making the active sight lost
9 of 10
Proteins can be used for buiding/strcutural material,hormones...
antibodies and catalysts
