Flashcards in Chemical Reactions Deck (39)
Are enzymes consumed by the reaction that they catalyze?
Do enzymes alter the equilibrium of the reaction?
An inactive enzyme precursor which requires a biochemical change for it to become an active enzyme.
The protein component of an enzyme to which the coenzyme is attached.
Enzymatic reactions are affected by what three things?
The process where there is a loss of hydrogen electrons or a gain of oxygen. OIL GOO
An enzyme that causes oxygen in a compound to be changed to water.
An enzyme which oxidases a compound by removing a hydrogen.
The process in which there is a gain of hydrogen electrons or a loss of oxygen. RIG LOO
An enzyme which adds hydrogen to a compound.
The chemical process by which a carboxyl group is added or displaces a hydrogen atom.
The enzyme which catalyzes the addition of a carboxyl group.
The process in which a carboxyl group (-COOH) is removed from an organic compound as CO2, and is commonly replaced by a hydrogen atom.
The enzyme that catalyzes the release of CO2 from compounds.
Refers to the cleavage of a compound by the addition of water, they hydroxyl group being incorporated in one fragment and the Hydrogen atom in the other.
The enzyme that facilitates hydrolysis as in sucrase in the breakdown of sucrose.
The process of introducing a phosphate group into an organic molecule.
Enzyme which adds an inorganic phosphate to a substrate without using ATP.
The enzyme that removes a phosphate group from it's substrate by hydrolyzing phosphoric acid monoester into a phosphate ion and a molecule with a fee hydroxyl group.
An enzyme that transfers a phosphate group from a high-energy donor molecules such as ATP.
An enzyme which changes the configuration and NOT the composition of a compound.
A type of isomerase which moves one group to another part in the same chemical compound.
An enzyme that catalyzes the TRANSFER of a functional group from one molecule to another.
An enzyme that catalyzes the JOINING of two molecules.
Refers to the maximum velocity of a reaction and is proportional to enzyme concentration.
The substrate concentration required to reach 1/2 Vmax.
Substance which slows down the rate of reaction of any enzyme.
