acetyl CoA (acetyl coenzyme A)
What is it and for what is it used?
Small water-soluble molecule that carries acetyl groups in cells.
actin filaments
Protein filament, 7-nm wide, formed from a chain of globular actin molecules. A major constituent of the cytoskeleton of all eucaryotic cells and especially abundant in muscle cells.
activation energy
The extra energy that must be acquired by a molecule to undergo a particular chemical reaction.
active site
Specialized region of an enzyme surface to which a substrate molecule binds before it undergoes a catalyzed
reaction.
adherens junction
Cell junction in which the cytoplasmic face is attached to actin filaments.
ADP (adenosine 5'-diphosphate)
Nucleotide that is produced by hydrolysis of the terminal phosphate of ATP.
allosteric
Describes a protein that can exist in two or more conformations depending on the binding of a molecule (a
ligand) at a site other than the catalytic site. Allosteric proteins composed of multiple subunits often display a cooperative response to ligand binding, because the binding of a ligand to one subunit facilitates the binding
of ligands to the other subunits.
aminoacyl-tRNA synthetase
Enzyme that attaches the correct amino acid to a tRNA molecule to form an aminoacyl-tRNA.
