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...

BIO 354 Cell Bio Lab Exam | Questions and Answers Imagine you are a scuba diver the size of a virus exploring huge algae cells. If you wanted to see how the water molecules are split inside the thylakoids space, how many membranes would you have to cross to get there? 3 You would go through the cell wall, to get the plasma membrane then you would be inside the cytoplasm. From there you would swim to the chloroplast and cross the outer and I. Er membranes to get the storms, where you'd see ...
