Substrate

Tastatur-Befehle:

= drehen,

= vor-/rückwärts,

= scrollen

The reactant an enzyme acts on

Enzyme-Substrate Complex

Tastatur-Befehle:

= drehen,

= vor-/rückwärts,

= scrollen

The enzyme plus the substrate bonded together

Active site

Tastatur-Befehle:

= drehen,

= vor-/rückwärts,

= scrollen

The restricted region of the enzyme that binds to the substrate.

Induced Fit

Tastatur-Befehle:

= drehen,

= vor-/rückwärts,

= scrollen

The process of an enzyme slightly altering its shape to form closer to the substrate

Cofactor

Tastatur-Befehle:

= drehen,

= vor-/rückwärts,

= scrollen

Non protein helper for catalytic activity

Competitive Inhibitors

Tastatur-Befehle:

= drehen,

= vor-/rückwärts,

= scrollen

Resemble the normal substrate and compete with the substrate for admission to the active site

Non-competitive inhibitors

Tastatur-Befehle:

= drehen,

= vor-/rückwärts,

= scrollen

Bind to the enzyme somewhere other than the active site, which alters the enzyme's shape, slowing enzymatic reactions

Allosteric Regulation

Tastatur-Befehle:

= drehen,

= vor-/rückwärts,

= scrollen

when a protein's function at one site is effected by the binding of a regulatory molecule at another

Cooperactivity

Tastatur-Befehle:

= drehen,

= vor-/rückwärts,

= scrollen

A substrate molecule binding to the active site in a multisubunit enzyme triggers a shape change in all subunits that increases the catalytic activity

Feedback Inhibition

Tastatur-Befehle:

= drehen,

= vor-/rückwärts,

= scrollen

A system where a metabolic pathway is switched off by the inhibitory binding of its end product to an enzyme that acts early in the pathway
