Term
Enzyme(s)
Definition
A specialized protein that acts as a catalyst and controls the rate of chemical reactions within cells. Its function depends on its structure
Term
Substrate
Definition
Reactants affected by enzymes in an enzyme catalyed reaction
Term
Active Site
Definition
The location on an enzyme where the substrate binds
Term
Activation Energy
Definition
The minimum amount of energy that substrates need to react
Term
Inhibitors
Definition
Molecules that bind to an enzyme and prevent it from functioning
Term
Denature
Definition
A condition when a protein unravels and loses its shape so that its function is affected
Term
Catalyst
Definition
Any substrate that speeds up chemical reactions
Term
Products
Definition
Compounds released from an enzyme catalyed reation
Term
Coenzyme
Definition
NON-protein substrates that help enzymes by transporting electrons, ions, or atoms between substrates and activate an enzyme
Term
Lock and Key Model
Definition
The condition that describes how enzymes exactly fit their substrates at the active site
Term
Induced Fit
Definition
A slight bending of the enzyme around the substrate making it fit better and weakening the bonds
Term
Surcrose
Definition
A disaccharide molecule consisting of the two monosaccharides, glucosem and frutose.
