The minimum quantity of energy that the reacting species must possess in order to undergo a specified reaction.

The transformation of one molecule to a different molecule inside a cell. Biochemical reactions are mediated by enzymes, which are biological catalysts that can alter the rate and specificity of chemical reactions inside cells.

A nonprotein 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. Most competitive inhibitors function by binding reversibly to the active site of the enzyme.

A substance produced by a living organism that acts as a catalyst to bring about a specific biochemical reaction.

The enzyme unit (U) is a unit for the amount of a particular enzyme. 1 U is defined as amount of the enzyme that produces a certain amount of enzymatic activity, that is, the amount that catalyzes the conversion of 1 micro mole of substrate per minute.

How much enzyme you have in a given amount of solution.

Any metal with a specific gravity of 5.0 or greater, especially one that is toxic to organisms (ex: lead, mercury, copper, and cadmium.)

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.

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.

a figure expressing the acidity or alkalinity of a solution on a logarithmic scale on which 7 is neutral, lower values are more acid, and higher values more alkaline. The pH is equal to -log10 c.

The substance on which an enzyme acts.

Substrate Concentration

By increasing the substrate concentration, the rate of reaction will increase due to the likelihood that the number of enzyme-substrate complexes will increase; this occurs until the enzyme concentration becomes the limiting factor.

Any of a group of organic compounds that are essential for normal growth and nutrition and are required in small quantities in the diet because they cannot be synthesized by the body.

Term	Definition
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. Biochemical reactions are mediated by enzymes, which are biological catalysts that can alter the rate and specificity of chemical reactions inside cells.
Coenzyme	A nonprotein 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. Most competitive inhibitors function by binding reversibly to the active site of the enzyme.
Enzyme	A substance produced by a living organism that acts as a catalyst to bring about a specific biochemical reaction.
Enzyme Activity	The enzyme unit (U) is a unit for the amount of a particular enzyme. 1 U is defined as amount of the enzyme that produces a certain amount of enzymatic activity, that is, the amount that catalyzes the conversion of 1 micro mole of substrate per minute.
Enzyme Concentration	How much enzyme you have in a given amount of solution.
Heavy Metal	Any metal with a specific gravity of 5.0 or greater, especially one that is toxic to organisms (ex: lead, mercury, copper, and cadmium.)
