What is a quaternary structure?
Result of two+protein subunits assembling to form a larger, biologically active protein complex.
What a secondary structure?
Describes alpha helices and beta sheets that are formed by hydrogen bonding between backbone atoms located near eachother in polypeptide chain.
What is a tertiary structure?
When protein folds into complex 3D shape stabilized by interactions between side chain R groups of amino acids.
Primary structure.
Sequence of amino acids in a protein.
Proteins are polymers of...
Amino acids.
The secondary structure of a protein results from...
Hydrogen bonds.
A competitive inhibitor...
Has a structure similar to the substrate that it can bond to the enzyme just like the substrate.
Noncompetitive inhibitor...
Binds to a site on the enzyme that is not the active site.
Irreversible inhibitor...
Forms a covalent bond with an amino acid side group within the active site which prevents substrate from entering the active site.
Also prevents catalytic activity.
The competitive inhibitor competes with the substrate for the _______ on the enzyme.
Active site.
When the noncompetitive inhibitor is bonded to the enzyme the shape of the _____ is distorted.
Enzyme.
Name a polymer that is composed of amino acids.
Proteins.
Enzyme inhibitors disrupt normal interactions between an enzyme and its...
Substrate.
What monomer makes up RNA?
Nucleotides.
Name a statement about the formation of polypeptides from amino acids...
Bond forms between carboxyl functional group of one amino acid and the amino functional group of the other amino acid.
