Apoenzyme + Cofactor =

small organic molecule that serves as a cofactor in a conjugated enzyme

what are the Typical inorganic ion cofactors: (Activators)

Oxidoreductase

Is an energy that catalyzes an oxidation-reduction reaction .
Requires a cofactor that is oxidized or reduced as the substrate is reduced or oxidized

what type of Major Classes of Enzymes that Lactate Dehydrogenase belong?

An enzyme that catalyzes the transfer of a functional group from one molecule to another

catalyzes the transfer of an amino group from one molecule to another

play a major role in metabolic energy-production reactions, catalyze the transfer of a phosphate group from adenosine
triphosphate (ATP) to give adenosine diphosphate (ADP) and a phosphorylated product.

An enzyme that catalyzes a hydrolysis reaction in which the addition of a water molecule to a bond causes the
bond to break

effect the breaking of glycosidic bonds in oligo- and polysaccharides

effect the breaking of peptide linkages in proteins

effect the breaking of ester linkages in triacyglycerols.

An enzyme that catalyzes the addition of a group to a double bond or the removal of a group to form a double
bond in a manner that does not involve hydrolysis or oxidation

effects the removal of the components of water from a double bond

effects the addition of the compositions of water to a double bond.

An enzyme that catalyzes the isomerization (rearrangement of atoms) of a substrate in a reaction, converting it
into a molecule isomeric with itself

An enzyme that catalyzes the bonding together of two molecules into one with the participation of ATP

relatively small part of an enzyme’s structure that is actually involved in catalysis.

intermediate reaction species that is formed when a substrate binds

The active site in the enzyme has a fixed, rigid geometrical conformation. Only substrates with a complementary
geometry can be accommodated at such a site, much as a lock accepts only certain keys

Extent to which an enzyme’s activity is restricted to a specific substrate, a specific group of substrate, a specific
type of chemical bond or a specific type of reaction.

Allows for small changes in the shape or geometry of the active site of an enzyme to accommodate a substrate. A
good analogy is the changes that occur in the shape of a glove when a hand is inserted into it.

Enzyme will catalyze only one reaction. This most restrictive of all specificities is not common

is an enzyme with absolute specificity

Enzyme will act on a particular type of chemical bond, irrespective of the rest of the molecular structure

is the most
general of the common specificities.

Enzyme will act on a particular stereoisomer

slows or stops the normal catalytic function of an enzyme by binding to it.

A molecule that sufficiently resembles an enzyme substrate in shape and charge distribution that it can compete
with the substrate for occupancy of the enzyme’s active site.

A molecule that decreases enzyme activity by binding to a site on an enzyme other than the active site

A molecule that inactivates enzymes by forming a strong covalent bond to an amino acid side- chain group at the
enzyme’s active site
