Photosynthesis Process in Chloroplasts: Light Reactions & Calvin Cycle Explained #210133 (License: Personal Use)

The image depicts the internal structure of a chloroplast, highlighting the thylakoid membranes where light-dependent reactions occur (generating ATP, NADPH, and O₂ from H₂O and light), and the stroma where the Calvin cycle fixes CO₂ into sugar using those energy carriers. Arrows indicate the flow of molecules-light energy drives electron transport, while ADP+P and NADP⁺ are recycled to sustain the process. Key inputs (H₂O, CO₂, light) and outputs (O₂, sugar) are clearly labeled for educational clarity.

Used in biology education websites, textbooks, or science blogs to explain plant physiology and photosynthesis; targets students, teachers, and curious learners seeking foundational understanding of how plants convert solar energy into chemical energy.
