control the metabolism of the cell (globular proteins catalysing biochemical reactions) - they lower the minimum energy/activation energy that reactants need to react, which increases the reaction rate
1 of 5
Enzyme environment
watery environment: enzymes & substrate mix/collide - collisions allow substrate to bind to the active site on the enzyme so the reaction can occur
2 of 5
General formula
Enzyme + substrate --> enzyme*substrate --> enzymes*product --> enzyme + product (E+S --> ES --> EP --> E+P)
3 of 5
Active site
where specific substrates can attach
4 of 5
fastest enzyme
acetylcholinesterase - active in synapses of nerves & muscle fibres, hydrolyses the acetylcholine to choline & an acetate group (catalyses 3*10^7 molecules of acetylchol
