3.4 Photosynthesis - AP Biology (Updated 2025-2026)

In this video, I provide the basics of photosynthesis as well as its origins, then provide an overview of the two main processes involved in turning light energy into chemical bonds in sugar molecules: the light reactions and the Calvin Cycle. I then go into detail about the light reactions and how they are used to make ATP. Notes: https://drive.google.com/file/d/1MmdL...
