ATP Energy Cycle Diagram - Photosynthesis & Cellular Respiration Explained #2282172 (License: Personal Use)

The image depicts the ATP-ADP energy cycle central to cellular metabolism: sunlight (left) energizes electrons that drive phosphorylation, converting ADP + inorganic phosphate (P) into ATP (top), which later hydrolyzes back to ADP + P, releasing energy for biological work. Key symbols include yellow circles for phosphate groups (P), green spheres for adenine (A), cyan pentagons for ribose, and purple arrows indicating reaction directionality. The word “Energy” emphasizes the transformation’s purpose.

Used in educational biology web pages, textbook digital supplements, or MOOCs explaining bioenergetics, photosynthesis, or cellular respiration; targets students and educators seeking visual reinforcement of ATP’s role as an energy currency.
