Krebs cycle

Question 1

rate limiting enzyme & step

Answer 1

Isocitrate dehydrogenase
изоцитрат-дехидрогеназа
isocitrate -> alphaKetogutarate

Question 2

net products (from 1 pyruvate)

Answer 2

2 CO2
3 NADH
1 FADH2
GTP
COA

Question 3

cycle in order

Answer 3

0. Acetyl CoA
1. Citrate (лимонена киселина)
2. Isocitrate ( изоцитрат)
3. Alpha-Ketoglutarate (алфа-кетоглутарат)
4. Succinyl-CoA (сукцинил КоА)
5. Succinate (сукцинат)
6. Fumarate (фумарат)
7. Malate (Ябълчена киселина/ LМалат)
8. Oxaloacetate (оксалацетат)
9. • 0. —-> 1.

Question 4

citrate to isocitrate enzyme

Answer 4

acomitase

Question 5

at which steps is NADH produced
at which step is FADH2 produced

Answer 5

NADH:
• isocitrate -> alphaKG
• alphaKG-> succinyl-CoA
• Malate -> oxaloacetate

FADH2:
• Succinate->Fumarate
