Grana and stroma

  1. Jun 11, 2005 #1
    What is the difference between grana and stroma thylakoids ?
    Could you also give me an example showing that photosynthesis is the reverse of respiration ? Thank you

    a grana is a stack of multiple thylakoids.

    For your second question, just look at the chemical equation for photosynthesis and cell respiration and you'll find that they are almost exact opposites.
    Photsynthesis: 6CO2 + 6H2O + LIGHT ENERGY--> C6H12O6 + 6O2
    Respiration: C6H12O6 + 6O2--> 6CO2 + 6H2O + ENERGY RELEASED (ATP
