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.
|

Nucleotides.
|
Name a statement about the formation of polypeptides from amino acids...
|
