enzyme-substrate-complex and product
|
-formed when enzyme and substrate interact -once formation of enzyme - substrate complex is complete the substrate molecule undergoes a chemical reaction and is converted to a new product |
|
amount of substrate or enzyme present
|
concentration of substrate increases, increasing the reaction rate until the enzyme becomes saturated with substrate, where the reaction rate will platue
|
|
coenzymes
|
essential for particular enzymes activity, usually donate electrons or protons, most are derived from vitamins
|
|
cofactors
|
metallic cations that some enzymes require in order to catalyse a reaction, most are derived from vitamins
|
|
metabolic pathways
|
a series of chemical reactions occurring within a cell, these reactions are catalyzed by enzymes, where the product of one enzyme acts as the substrate for the next.
|
|
end product inhibition
|
if there is an excess of the end product in a metabolic pathway, the whole pathway is switched off and intermediates do not build up
|
|
rational drug design
|
the active site of a molecule is determined ad a second molecule (drug) is constructed to fit into that active site to inhibit the activity of the first molecule
