Link reaction & Krebs cycle

Question 1

Link Reaction?

Answer 1

1. carboxyl group is removed from pyruvate/CO2 is produced
2. de carboxylation and dehyrogenase produces an aceytl group
3. aceytl group combines woth co enzyme A to form acetyl CoA
4. . NAD becomes reduced

Question 2

Krebs Cycle

Answer 2

1. Aceytl group combines with a 4C molecule to form citrate 6C
2. Citrate is de-carboxylated and dehydrogenated to form a 5C molecule, CO2 and NAD
3. 5C molecule is further de carboxylated to produce a 4C molecule, CO2 and NAD
4. 4C molecule combines with COA to produce ATP
5. 4 carbon compound is regenerated into oxoacetate

Question 3

Answer 3

2 reduced NAD
0 reduced FAD
2 CO2
0 ATP

Question 4

Products of Krebs cycle

Answer 4

6 Reduced NAD
2 Reduced FAD
4 CO2
2 ATP
