enzymes Flashcards
what are enzymes made up of
amino acids=proteins (globular proteins)
are enzymes made up of high molecular weight
yes
what do globular proteins have
a spherical shape, alpha helix molecules, 1y, 2y and 3y structure- hydrogen, ionic and disulphide bonds
what do intracellular enzymes do
the synthesis of polymers into monomers in cells?????
what does anabolic mean
building up molecules it is required for growth
what does catabolic mean
breaking down molecules into sub units
eg of work down by a catabolic enzyme
digestion- amalase breaks carbohydrates into starch then glucose
eg of work down by anabolic enzymes
nail growth
what are enzymes
biological catalysts that speed up the ror without getting used up in the reaction and changing the produced substances.
what is enzymes specificity
the ability of an enzyme to select a specific substrate from a range of chemically similar compounds
what is a cofactor
a non protein chemical compound or metallic ion that is required for the enzymes activity as a catalyst. they can be considered as helper molecules that assist in biochemical reactions
what is a holoenzyme
refers to the active enzyme with its nonprotein component.
what is an apoenzyme
is an inactive enzyme without its nonprotein part
