ENZYMES
|
A protein capable of speeding up specific
chemical reactions by lowering the energy required to activate or start the reaction but that remains unaltered in the process |
|
|
TYPES OF ENZYMES
|
LYSOZYME
|
|
|
ACTIVATION OF CHEMICAL REACTION
|
destabilizing existing chemical bonds BREAKS DOWN PREVIOUS CHEMICAL BONDS
|
|
|
AFFECT IT
|
BY WEAKING THE BONDS BY DRAWING AWAY ELECTRONS
SPEEDS THE REACTION UP |
|
|
CATALYST
|
Reactions become more spontaneous if their
activation energy is lowered |
|
|
ACTIVE SITE
|
REACTANT FITS
|
|
|
BINDING SITE
|
REACTANT BINDS W ENZYMES
|
|
|
INDUCED FIT
|
ENZYME AND REACTANT FITS PERFECTLY
|
|
|
BIOCHEMICAL REACTION
|
ENZYMES CATAYLZE REACT
|
|
|
TEMPATURE VS. ENZYMES
|
TEMP INCREASE BOND BECOMES WEAK TO HOLD PEPTIDE CHAINS
|
|
|
PH VS. ENZYMES
|
WHEN PH IS 6 WORKS BEST...BUT WHEN GET HIGHER ITS HARDER TO FUNCTION
|
|
|
ALLOSTERIC
|
the signal molecules bind on a site on the enzyme
|
|
|
ACTIVATOR
|
change the shape of the enzyme so that it can bind
substrate |
|
|
REPRESSOR
|
inhibit the enzyme when bound
|
|
|
COMPETITIVE
|
BLOCKS ACTIVE SITE SO SUBSTRATE CANNOT BIND
|
|
|
NON COMPETITEVE
|
CHANGE THE SHAPE OF ENZYME SUCH THAT IT IS UNABLE TO BIND TO THE SUBSTRATE
|
|
|
FEEDBACK INHINITITION
|
PRODUCT OF REACTION ACT AS REPRESSOR
|
