|
enzymes |
a substance produced by a living organism that acts as a catalyst for specific biochemical reaction ( biological catalyst ) reactance |
|
|
substrate |
reactant that has binds with enzyme |
|
|
competitive inhibitors |
a molecule that competes with substrate to bind in active site of enzyme |
|
|
non competitive inhibitors |
( causes enzymes to change shape ) binds to site other than active site |
|
|
active site |
location on enzyme where substrate binds |
|
|
activation energy |
minimum input of energy that will start a chemical reaction |
|
|
what will reduce the reaction rate in an enzyme? |
Inhibitors Activators Salinity Ph Temperature Substrate Concentration Enzyme |
|
|
enzymes speeds up: |
Chemical reaction |
|
|
what will reduce the reaction rate in an enzyme |
Temp Ph Cofactors and Coenzymes Inhibitors |
|
|
Denature |
The change in a proteins shape and consequent loss of its function brought about by heat, agitation, acid/base, alcohol, heavy metals, or other agents. Does not affect the primary structure of the protein but reduces its function |
|
|
reaction rate |
The change in concentration of a reactant or product per unit time |
|
|
what is the importance of shape to an enzyme? |
the shape of enzymes determines it's function...Which substrate the enzyme binds to and catalyzes is determined by the shape of it's binding groove ( If shape is lost the enzyme cannot function anymore ) |
