Answer:
Stage 2 of photosynthesis depends on stage 1 and Stage 3 depends on stage 2
Step-by-step explanation:
Stage 1 of photosynthesis deals with the formation of ATP and NADPH.ATP act as energy currency and NADPH act as reducing agent in the dark reaction or stage 2
Stage 2 of photosynthesis result in the formation of phosphoglyceraldehyde(PGALD) which is used to regenerate Ribulose bisphosphate(RUBP).The regeneration of RUBP is the important event of stage 3
