I: | It shows that the Krebs cycle is an amphibolic pathway. |
II: | An amphibolic pathway is a type of catabolic pathway that is involved in the production of ATP. |
1. | (1) is NADH; 4 is FAD; 6 is fumarate; 8 is oxygen and 10 is ATP |
2. | (2) is NAD+ ; 4 is FADH2; 6 is succinate; 8 is oxygen and 10 is ADP |
3. | (1) is NADH; 4 is Fumarate; 6 is FAD; 8 is water and 10 is ATP |
4. | (2) is NAD+; 3 is succinate; 6 is FAD; 8 is oxygen and 10 is ADP |
I: | Oxidative decarboxylation steps are Step 4 and Step 5. |
II: | The reducing power 'NADH' is generated at Step 4, Step 5 and Step 9. |
III: | FADH2 is generated at Step 7. |

I: | Yeasts perform this metabolic conversion when growing in the absence of oxygen. |
II: | The metabolic conversion of pyruvate into acetaldeyhde is catalysed by the enzyme pyruvate dehydrogenase. |
III: | The metabolic conversion of acetaldehyde into ethanol is catalysed by the enzyme alcohol dehydrogenase. |

I: | If fatty acids were to be respired, they would enter the respiratory pathway as acetyl CoA. |
II: | Glycerol enters the respiratory pathway after being converted to PGAL. |
III: | Amino acids enter the respiratory pathway at some stage within the Krebs cycle but never as pyruvate or acetyl CoA. |
