Kerb Cycle

Question 1

Oxidative decarboxylation 1-4

Answer 1

Acetyl CoA-> CO2

• 3: isocitrate is decarboxylated and dehydrogenated to form 5C and NADH
• 4: another CO2 is lost, NAD + reduce to NADH

Question 2

Substrate level phosphorylation

Answer 2

Directly px 2 net molecules of ATP per glucose mole

Question 3

Oxidative phosphorylation

Answer 3

• reduced coenzymes (6NADH+ H+ and 2 FADH2) carry high energy e to ETC
• oxidised by molecular oxygen in ETC

Question 4

5 pdts?

Answer 4

1. 2 oxaloacetate are regenerated for Kerb cycle
2. 6NADH for OP
3. 2FADH2 for OP
4. 2ATP for SLP
5. 4CO2
