Answer 1

1. Fructose phosphate is made and can be converted to glucose, and combined with glucose to make sucrose for transportation around the plant.
2. A- glucose may be converted to starch for storage
3. B-glucose may be used for cellulose for cell walls

Question 2

How can fats be made from the Calvin cycle?

Answer 2

Acetyl coenzyme A can be synthesised by GP and made Into fatty acids. TP can be converted into glycerol, and under condensation this makes triglycerides.

Question 3

How can proteins be made from the Calvin cycle?

Answer 3
