Well, the light reactions are where my polyhouse baccas trap sunlight to make ATP and NADPH. Photosystem II kicks it off by splitting water, releasing oxygen we breathe. Then plastoquinone and cytochrome b6f shuttle electrons to pump protons, creating a gradient that spins ATP synthase—our molecular mill that churns out ATP.
And the specific thing? I see this daily. My drip system is that proton gradient—a potential I built with a loan. The water pressure turning the emitters is my ATP synthase, creating tiny bursts of growth. The books show it in chloroplasts, but I’ve built it here in plastic sheets.
