Vika [28.1K]

NADPH is formed on the stromal side of the thylakoid membrane, so it is released into the stroma.

romanna [79]
It would have 20 protons, 20 neutrons, and 20 electrons. Protons and electrons are USUALLY (I say usually because of the different types of atoms) the same as the atomic number. To find neutrons you take the atomic mass minus the atomic number. 40-20=20
