IB Biology Topic 8.3 (HL): Photosynthesis

This video starts with a basic review of SL photosynthesis and introduces HL photosynthesis. To understand all the reactions, the structure of chloroplasts is then covered. Afterwards, the process of photosynthesis is covered in detail, including the light-dependent reactions, including the electron transport chain and chemiosmosis, followed by the light-independent reactions. This is then reviewed with an example Paper 2 question. The video concludes by discussing how Calvin determined the Calvin cycle via his lollipop experiment with algae.
