enzymes

?
indented area on the surface of an enzyme molecule with a shape that is complementary to the shape of the substrate molecule
active site
1 of 18
chemical that speeds up the rate of a reaction and remains unchanged and reusable at the end of the reaction
catalyst
2 of 18
outside the cell
extracellular
3 of 18
inside the cell
intracellular
4 of 18
the chemical reaction that take place inside living cells or organisms
metabolic
5 of 18
molecule produced from substrate molecules, by an enzyme-catalysed reaction
product
6 of 18
molecule that is altered by an enzyme-catalysed reaction
substrate
7 of 18
a substance that has to be present to ensure that an enzyme-catalysed reaction takes place at the appropriate rate. some are part of the enzyme structure and others form temporary associations with the enzyme
cofactor
8 of 18
cofactor that is part of the enzyme structure
prosthetic group
9 of 18
a cofactor that forms temporary associations with the enzyme
mineral ion
10 of 18
a cofactor that forms temporary associations with the enzyme
organic coenzyme
11 of 18
complex formed by temporary binding of enzyme and substrate molecules during an enzyme catalysed reaction
enzyme-substrate complex
12 of 18
enzyme molecule with product molecule in its active site. the two are joined temporarily by non-covalent forces
enzyme-product complex
13 of 18
enzyme molecule with substrate molecule in its active site. the two are joined temporarily by non-covalent forces
enzyme-substrate complex
14 of 18
number of molecule per unit volume
concentration
15 of 18
inhibition of an enzyme, where the inhibitor molecule has a similar shape to that of the substrate molecule and competes with the substrate for the enzymes active site. it blocks the active site and prevents formation of enzyme-substrate complexes
competitive inhibition
16 of 18
a substance the reduces or stops a reaction
inhibitor
17 of 18
the competitor molecule attaches to the enzyme but not the active site. changing the shape of the active site, which prevents ES complexes forming, as the enzyme active site is no longer complementary in shape to the substrate molecule
non-competitive inhibition
