AHL Photosynthesis

Before we start this section you have to ask yourself do you actually know the information we studied about photosynthesis in topic 3? If the answer is no go back and remind yourself of the standard level information first.

To help us to understand the process we will use this presentation from I-Biology. We will use this animation from Mc Graw Hill to help us understand the light dependent reactions. We will compare the light dependent reactions in the chloroplasts with the electron transport chain and oxidative phosphorylation that occurs in respiration. Why might the similarities be significant? Respiration can be seen here.
