The ability to do work
Energy
The law that states that matter cannot be created or destroyed but can be converted from one form to another.
First Law of Thermodynamics
Another name for exergonic reactions
C --> A + B
degradative or catabolic
A protein whose shape and chemical properties give it the ability to greatly speed up particular chemical reactions
enzyme
The process of an enzyme losing its proper shape due to heat or some other factor.
Denaturation
Any system left to itself goes from order to disorder.
2nd Law of Thermodynamics
Another name for endergonic reactions.
A + B --> C
Biosynthetic or anabolic
Coenzyme
The shutting down of enzyme activity due to a non-substrate binding to the allosteric site.
Allosteric inhibition
Three things that affect enzymatic activity
Temperature, pH, & Tonicity (or concentration)
The resulting molecule(s) of a chemical reaction are called what?
Product
A nucleotide that carries the chemical energy for metabolism in a cell that functions like a rechargeable battery
ATP
An indentation of an enzyme's surface where substates temporarily attach to the enzyme and react to form the product.
Active site
Denaturation destroys an enzyme's ____________
Active site
Chemicals that react with each other in a chemical reaction
Reactants
The reactant that temporarily attaches to an active site of an enzyme in which the reaction occurs.
Substrate
The crevice on the enzyme's surfact where a non-substrate (often a heavy metal) may bind resulting in the distortion and loss of function of the enzyme's active site.
Allosteric site
Enzymes convert substrates into ____________ using their active sites.
Products
The sum total of all chemical reactions
Metabolism
