Enzyme

TermDefinition
Activation Energy The minimum quantity of energy that the reacting species must possess in order to undergo a specified reaction.
Biochemical Reaction The transformation of one molecule to a different molecule inside a cell.
Coenzyme A non-protein compound that is necessary for the functioning of an enzyme.
Competitive Inhibitor A form of enzyme inhibition where binding of the inhibitor to the active site on the enzyme prevents binding of the substrate and vice versa.
Enzyme A substance produced by a living organism that acts as a catalyst to bring about a specific biochemical reaction.
Enzyme Activity The amount that catalyzes the conversion of 1 micro mole of substrate per minute.
Enzyme Concentration Concentration of enzymes.
Heavy Metal A metal of relatively high density, or of high relative atomic weight. Poisonous if ingested.
Induced Fit Model A proposed mechanism of interaction between an enzyme and a substrate. It postulates that exposure of an enzyme to a substrate causes the active site of the enzyme to change shape in order to allow the enzyme and substrate to bind.
Metabolism The chemical processes that occur within a living organism in order to maintain life.
Non-competitive Inhibitor A type of enzyme inhibition where the inhibitor reduces the activity of the enzyme and binds equally well to the enzyme whether or not it has already bound the substrate.
pH Measurement of how acidic or basic a chemical is.
Substrate The substance on which an enzyme acts.
substrate concentration Concentration of substrates.
thyroid A large ductless gland in the neck that secretes hormones regulating growth and development through the rate of metabolism.
thyroxin The main hormone produced by the thyroid gland, acting to increase metabolic rate and so regulating growth and development.
