Photosynthesis Light Reactions and Calvin Cycle Explained #210107 (License: Personal Use)

This diagram illustrates the two main stages of photosynthesis: the light-dependent reactions (in the thylakoid membranes) convert solar energy into chemical energy carriers-ATP and NADPH-while the Calvin Cycle (in the stroma) uses those molecules to fix CO₂ into organic sugars. Arrows indicate inputs (light, ADP, Pi, NADP⁺) and outputs (O₂, ATP, NADPH, sugars), highlighting the cyclical flow of energy and matter.

Used in biology education pages, textbook supplements, or science explainer articles to clarify photosynthetic processes; targets students, educators, and curious learners seeking foundational understanding of plant metabolism.
