Definition
a)The transfer of an inorganic phosphate
group (Pi) from one substrate to another
by way of an enzyme
b) the addition of a phosphate (PO43−)
group to a protein or other organic
molecule
c) the gain of electrons or a decrease in
oxidation state by a molecule, atom, or
ion.
d)metabolic pathway in which the
mitochondria in cells use their structure,
enzymes, and energy released by the
oxidation of nutrients to reform ATP
e) the loss of electrons or an increase in
oxidation state by a molecule, atom,
or ion.
f) change in the state of water vapor to
liquid water when in contact with any
surface
