Q
what happens to FADH and NADH in oxidative phosphorylation?
A
they supply electrons and to the electron transport chain, provide H+ ions to help establish the electrochemical gradient, and are reoxidised
1
Q
are NAD and FAD prosthetic groups?
A
FAD is a prosthetic group but NAD is not
2
Q
coenzymes defintion
A
small organic non-protein molecules that bind temporarily to the active site of enzymes and assists it in its function
3
Q
why do coenzymes need to be recycled back to their original state after a reaction occurrs?
A
because they are chemically changed during the reaction
4
Q
what are the 2 types of cofactor?
A
coenzymes
prosthetic groups
5
Q
cofactor definition
A
a substance that has to be present to ensure that an enzyme-catalysed reaction take place at the appropriate rate
