|
what is the active site of an enzyme
|
pockets of clefts that bind with substrates
|
|
|
what is the process enzymes do
|
enzymes bind with a substrate and place stresses on a bond in the substrate. subsequently the substrate breaks apart(bond breaks) and products are released from the enzyme
|
|
|
what are prosthetic group
|
non protein componnet of conjugated protein.
|
|
|
what are cofactors
|
non amino acids such as vitamens and metals that assist in enzyme functions(may be found in the active site)
|
|
|
what is coenzyme
|
non protein organic factor such as a vitamin. IE NAD+
|
|
|
what Vmax of an enzyme
|
maximum reaction rate of an enzyme
|
|
|
what is the Km
|
the substrate concentration that produces half the maximum reaction rate.
|
|
|
what is competitive inhibition of enzymes
|
chemicals that compete for the same binding site as the substrate
|
|
|
what noncompetitive inhibition of an enzyme
|
chemicals bid to an enzyme in a location other than the active site. making it unable to function properly
|
|
|
what are allosteric interactions of an enzyme
|
they block the active site so that the enzyme cannot function properly
|
|
|
what is the optimum temperature for most enzymes?
|
35-40 degree C. optimum for hydrogen bonds
|
|
|
what is the optimum pH range of enzymes
|
between 6-8 but there are exceptions.
