Chapter 10 - Citrate Cycle

Question 1

Citrate Cycle

Answer 1

Control pathway in oxidative respiration, converts acetyl units to CO2 with the production of FADH2, NADH, and ATP

Question 2

Product

Answer 2

3 NADH, 1 FADH2, 1 GTP, transfer 8 electrons

Question 3

Redox Reaction

Answer 3

Acetyl-CoA + 3NAD + FAD + GDP + Pi + 2H2O > CoA + 2CO2 + 3NADH + 3H + FADH2 + GTP

Question 4

Pyruvate Dehydrogenase

Answer 4

Converts pyruvate to acetyl-CoA, necessary transition from glycolysis

Question 5

Step 1

Answer 5

Acetyl-CoA + Oxaloacetate + H2O (citrate synthase)> CoA + citrate

Question 6

Step 2

Answer 6

Citrate (aconitase)>< Isocitrate

Question 7

Step 3

Answer 7

Isocitrate + NAD (isocitrate dehydrogenase)> a-Ketoglurate + NADH + CO2 + H

Question 8

Step 4

Answer 8

a-Ketoglurate + CoA + NAD (a-ketoglutarate dehydrogenase)> Succinyl-CoA + NADH + CO2 + H

Question 9

Step 5

Answer 9

Succinyl-CoA + GDP + Pi (succinyl-CoA synthetase)>< Succinate + GTP + CoA

Question 10

Step 6

Answer 10

Succinate + FAD (succinate dehydrogenase)>< Fumarate + FADH2

Question 11

Step 7

Answer 11

Fumarate + H2O (fumarase)>< Malate

Question 12

Step 8

Answer 12

Malate + NAD (malate dehydrogenase)>< Oxaloacetate + NADH + H
