Krebs Cycle - Respiration

Question 1

1.

Answer 1

CoA passes Acetate onto Oxaloacetate (4C) to form Citrate (6C).

Question 2

2.

Answer 2

Citrate is decarboxylated and dehydrogenated to a 5C compound, emitting CO2 and reduced NAD.

Question 3

3.

Answer 3

5C compound is decarboxylated and dehydrogenated to a 4C compound, emitting CO2 and reduced NAD.

Question 4

4.

Answer 4

ATP is phosphorylated from ADP + Pi (substrate level phosphorylation), FAD is reduced and NAD is reduced, forming Oxaloacetate from the 4C compound.

Question 5

Where does it occur?

Answer 5

Mitochondrial matrix.

Question 6

Output

Answer 6

6 x reduced NAD, 2 x reduced FAD, 4 x CO2, 2 x ATP. (Occurs twice for every glucose molecule).
