Bio Section 4

Front 1

Active site

Back 1

Teh specific portion of an enzyme that binds the substrate by means of multiple weak interactions and taht forms teh pocket in which catalysis occurs

Front 2

Allosteric regulation

Back 2

teh binding of a regulatory molecule to a protein at one site taht affects the function of the protein at a different site

Front 3

Cofactor

Back 3

Any nonprotein molecule or ion taht is required for teh proper function of an enzyme. can be perminately or loosely bound w/ the enzyme

Front 4

Coenzyme

Back 4

An organic moleclue serving as a cofactor. Typically a vitamin

Front 5

cooperativity

Back 5

A kind of allosteric regulation whereby a shape change in one subunit of a protein caused by substarte binding is transmitted to all teh ohers, facilitating binding of subsequent substrate molecules,

Front 6

Competitive inhibitor

Back 6

A substance taht reduces teh activity of an enzume by entering teh active site in place of teh substrate whose structure it mimics

Front 7

Noncompetitive inhibitor

Back 7

A substance that reduces the activity of an enzyme by binding to a location remote from teh active site, changing teh enzume's shape so tat teh active site no longer functions correctly.
