Q: What happens during the light-dependent
reactions?
 
A: The light-dependent reactions use energy from
sunlight to produce oxygen & convert ADP and NADP+
into energy carriers ATP and NADPH.

Photosynthesis is a crucial process where plants use sunlight to produce energy in the form of ATP and NADPH through light-dependent reactions, leading to the creation of sugars in the light-independent reactions. Factors such as temperature, light, and water play essential roles in regulating photosynthesis, with variations observed in extreme conditions like C4 and CAM plants.
