Link light reactions to carbon fixation
A chloroplast diagram in a HL evolution tutorial shows ATP and NADPH moving from thylakoids to the Calvin cycle. Explain why those products are needed. Enter the answer and choose the interpretation that best matches the HL Biology evidence.
Worked practice: biological evidence and answer
Use the labelled biological evidence first, then connect it to the final answer.
