In this A level Biology video, Hazel talks you through the light dependent and light independent stages of photosynthesis, in all the detail required for the AQA A level examination. This includes looking at the role of light in photolysis and photoionisation, how NADPH and ATP are produced in the light dependent stage, and how the products of the light dependent stage are then used in the Calvin cycle to produce glucose.

These videos are designed to help with your AQA A level science revision.
