Unit 1 Key Area 6 Flashcards
1
Q
Metabolic Pathways
A
Integrated and controlled pathways of enzyme-catalysed reactions within a cell
2
Q
Anabolic reactions
A
Build up of a large molecule from a smaller molecule, requires energy
3
Q
Catabolic reactions
A
Break down of large molecules into smaller molecules, releases energy
4
Q
Induced Fit
A
when a molecule of a substrate enters the active site, the shape of the active site changes slightly to better fit the substrate after the substrate binds
5
Q
5 things an enzyme requires to function efficiently
A
temperature pH substrate concentration/correct substrate enzyme concentration product concentration
6
Q
Competitive inhibition
A
Inhibitor binds to the active site and prevents the substrate from binding to it
7
Q
Non-competitive inhibition
A
Inhibitor binds to a non-active site (allosteric) and changes the shape of the active site so that the substrate can’t bind
