Catalysis is the increase in the rate of a chemical reaction due to the participation of an additional substance called a catalyst.
A chemical reaction is a process that leads to the transformation of one set of chemical substances to another.
Enzymes are macromolecular biological catalysts.
Hydrogen ion is recommended by IUPAC as a general term for all ions of hydrogen and its isotopes.
Nicotinamide adenine dinucleotide phosphate, abbreviated NADP or, in older notation, TPN (triphosphopyridine nucleotide), is a cofactor used in anabolic reactions, such as lipid and nucleic acid synthesis, which require NADPH as a reducing agent.
In biochemistry, an oxidoreductase is an enzyme that catalyzes the transfer of electrons from one molecule, the reductant, also called the electron donor, to another, the oxidant, also called the electron acceptor.
Products are the species formed from chemical reactions.
In chemistry, a substrate is typically the chemical species being observed in a chemical reaction, which reacts with reagent to generate a product.
