The energy passes rapidly from molecule to molecule until it reaches a special chlorophyll molecule called P700, so named because it absorbs light in the red region of the spectrum at wavelengths of 700 nanometers. When one ovary is removed why does the remaining ovary increase in size? During photosystem II, the energy from light excites one of the electrons in chlorophyll, causing it to be lost to other receptor molecules that pass it along away from the chlorophyll. Are we going through an evolution with the Coronavirus Pandemic. C) generation of ATP is driven by a flow of protons (H+) through ATP synthase.
