Question

Explain how triose phosphate is produced and used in the chloroplasts of a plant

Answer 1

LIRs take place in stroma of chloroplast; and they produce carbohydrates; CO2 is fixed; to RuBP (a 5-C compound); by Rubisco; to form an unstable 6-C compound; which splits into 2 molecules of glycerate-3-phosphate; LDRs produce ATP and NADPH; of which ATP provides energy to reduce glycerate-3-phosphate; to triose phosphate; whilst NADPH provides hydrogen required to do so; Some 3-C sugars go to form hexose sugars; others make more RuBP; (Calvin cycle);
