What sunlight actually hits inside a leaf #photosynthesis #chloroplast #molecularbiology #biochemistry #scienceanimation #learnontiktok #learning #funfacts #coolscience #simulation #nanomachine #biotok #science #3danimation From a leaf to the atoms that catch the light, in one continuous dive. Every molecule here is a real structure from crystallography and cryo-EM: photosystem II (the water-splitting machine), cytochrome b6f, photosystem I, and ATP synthase, the rotary motor that makes ATP. Red and blue photons land on the antenna, the energy hops chlorophyll to chlorophyll into P680, electrons flow across the membrane, and protons spin the rotor.#atpsynthase #ATP #atp
