Understanding Photosynthesis: Role of NADP and Division into Light and Dark Stages

In photosynthesis, NADP plays a crucial role in carrying hydrogen into the dark stage for carbon dioxide reduction. The process is divided into light and dark stages where different components like chlorophyll, chloroplasts, and electron transfer mechanisms are involved. This division ensures efficient capture and utilization of light energy to produce carbohydrates essential for plant growth.
