a level biology

1. why is the krebs cycle important

2. whats the difference between oxidative phosphorylation and substrate level phosphorylation

3. what is the purpose of NAD and reduced NAD

thank you x

1. Krebs Cycle is important since it utilises the actyl CoA from the link's reaction to produce 4 NADH, 1 FADH, 1 ATP, and 2 CO2 per cycle.
2. Substrate level phosphorylation is basically the production of ATP with the absence of an electron transport chain where instead in involves the transfer of a phosphate group from a source such as creatine phosphate
3. They accept electrons and hydrogen ions. They are mainly used in oxidative phosphorylation.
