Cards (11)

  • what are the products of light dependent reaction?

    • ATP
    • reduced NADP
    • oxygen
  • where does the light dependent reactions take place?

    the thylakoid membranes
  • what is used to form the products in light dependent reactions?

    light
  • what is the product of light independent reaction?

    glucose
  • what is used to form glucose in light independent reaction?

    • ATP
    • reduced NADP
    • carbon dioixe
  • what do the light independent reactions occur?

    in the stroma
  • what is light harvested by?

    photosystems
  • what are photosystems?
    protein and chlorophyll
  • where are the photosystems found?

    on the thylakoid membrane
  • how many photosystems are involved?
    • photosystem 1 (PSI)
    • photosystem 2 (PSII)
    • so 2 photosystems
  • what occurs first?
    • light energy absorbed by PSII, a pair of electron is excited.
    • the excited pair of electrons passes through an electron transport chain via a series of redox reactions.
    • at the end of the electron transport chain, the electrons are passed to PSI.
    • as the electron pair moves through the electron transport chain, the energy of the electrons produces ATP by chemiosmosis.
    • light energy the absorbed by PSI, pair of electrons excited.
    • electrons go through electron transport chain, making ATP by chemiosmosis
    • electron pair added to NADP in storm to form reduced NADP.
