Light Dependent Reaction

• Where does the light-dependent reaction occur?

  In the thylakoid membrane.
• What does the thylakoid membrane contain?

  Pigments such as chlorophyll, enzymes, and proteins such as electron carriers.
• What occurs during photoionisation?

  Light energy is absorbed by pigments, electrons become excited and are lost, causing the pigments to be oxidised.
• What happens once the electrons are lost from pigments after photoionisation?

  They are taken up by an electron carrier molecule and are passed along an electron transfer chain.
• What happens to the electron carrier when it takes up electrons?

  It is reduced.
• What happens as electrons are passed along the transfer chain?

  Energy gets released.
• What is the energy released from the electron transfer chain used for?

  ATP production.
