Proteins Flashcards
What are coenzymes ?
Co e zynmes are derivatives of vita
Mins wthout which the enzyme cannot exhibit a y reaction.
………… accepts a particular group removed from substrate
Or donates a particular group to the substrate
Co enzyme
Co enzymes are also called c
Co substrate because the changes that take place in substrates are complimentary to the changes in coenzymes.
Properties of an enzyme includes?
(ASCRIZ)Active siteCatalytic ecficiencySpecificityBond SpecificityRegulationZymogens*Isoenzymes,
Specificity of enzymes are divided into
Absolute Specificity
*Stereo specificity
Enzyme molecule contains a pocket called……….
Active Site.
The active site contains ………..
Amino acid chains that create a three dimensional surface complementary. to the substance.
Metal activated enzymes… form only Loose and easily dissociable complexes with the metal without denaturing
TrueTfue
……..hold the metal tightly and do not release it even during extensive purification.
Metalloenzymes
Enzyme substrate is converted to ………which dessociates to ……… &……..
Enzyme product.
Enzyme &Product s
Active site of substrate may contain……….. ……. …… …
Hydroxl group of serine, hydroxyl group of tyrosine, S-H thiol group of cysteine or imindazolelle group of histidine
Enzymes having the same catalytic activity act on the same substrate, and produces the same product it originated at did site are calldd
Iso enzymee
Primary protein structures refer to…..
The linear sequence of amino acid residues in a polypeptide chain.Disulfide bonds are involved in primary protein structures
Folding of polypeptide chain along it’s long axis bring about
Secondary structure of proteins.
Folding of polypeptide chain forming secondary protein structure can be ……, ……. or …..
Ordered,disordered or random.
