Study Notes
Energy and ATP
- The primary form of energy currency in cells is ATP (Adenosine Triphosphate).
- Chemical energy is stored in the phosphate bonds of the ATP molecule.
- When ATP loses a phosphate group, it becomes ADP (Adenosine Diphosphate) and releases energy.
Photosynthesis and Light Energy
- When light energy is absorbed by chlorophyll, it excites high-energy electrons.
- These high-energy electrons play a crucial role in transferring energy during photosynthesis.
- Light energy is utilized to create sugars in autotrophs through the process of photosynthesis.
