General
✓✗The respiratory pathway is used in both the breakdown and synthesis of
- carbohydrates only, not fats
- nucleic acids only, not sugars
- vitamins only, not proteins
- carbohydrates, fats and proteins
General
✓✗Fatty acids enter the respiratory pathway after being degraded to
- acetyl CoA

General
✓✗The enzymes for alcoholic fermentation in yeast are
- pyruvic acid decarboxylase and alcohol dehydrogenase
- pyruvate dehydrogenase and citrate synthase
- hexokinase and aldolase
- lactate dehydrogenase and enolase
General
✓✗The NADH formed in the TCA cycle is oxidised
- by lactate dehydrogenase in the cytoplasm
- by NADP reductase in the chloroplasts
- by enzymes in the nucleus
- by the ETS in the inner membrane
General
✓✗Citric acid is a
