☀️ How Do Plants Capture Light Energy? ☀️
In this IB Biology video, we explore the light-dependent reactions of photosynthesis, where plants convert sunlight into chemical energy! You’ll learn about:
✅ Photosystems I & II – How they absorb light and excite electrons ⚡
✅ Electron Transport Chain – The step-by-step movement of electrons and energy transfer 🔄
✅ Water Splitting (Photolysis) – How oxygen is released as a byproduct 🌊➡️🌿
✅ ATP & NADPH Production – How energy carriers are generated through chemiosmosis and the proton gradient 💡
✅ Cyclic vs. Non-Cyclic Photophosphorylation – Comparing the two pathways 🔁
✅ How These Reactions Power the Calvin Cycle – The next step in photosynthesis 🌱
This video is essential for IB Biology, AP Biology, and plant science students who want to master the fundamentals of photosynthesis and its energy transformations!
