11.3 Light independent reaction

Question 1

Calvin cycle

Answer 1

1. CO2 diffuses into leaf through stomata and into stroma of chloroplasts
2. CO2 reacts with ribulose bi-phosphate catalysed by rubisco
3. 2 molecules of glycerate phosphate produced (3C)
4. Reduced NAPD used to reduce glycerate phosphate to triose phosphate requiring energy supplied by ATP from LDR
   5.NADP reformed and goes back to LDR
5. Some triose phosphate molecules converted to organic substances for plant eg. glucose
6. Most triose phosphate molecules are used to regenerate ribulose biphosphate using ATP from LDR
