AP BIOLOGY UNIT 2 TEST QUESTIONS WITH VERIFIED ANSWERS Compare and contrast P2 and P1. Photosystem II begins , which absorbs wavelengths at a wavelength of 680 nm. Here, energy is absorbed and passed along until it reaches P680 chlorophyll. When this chlorophyll is excited, it sends its electrons to the primary electron acceptor. Electrons are taken from H2O and passed to P680 to replace the electrons given to the primary acceptor. This forces O2 to form. The electrons are passed to ph...
