NADPH molecules are like little delivery trucks, each carrying a hydrogen atom to a waiting enzyme that needs the hydrogen atom to help build a sugar molecule.
NADPH molekulid on nagu tillukesed veoautod, mis toimetavad vesinikuaatomid ootevalmis ensüümi juurde, et see saaks neid kasutada suhkrumolekuli kokkupanemisel.
