the role of O2 as an electron acceptor during C4 photosynthesis.
This makes it very easy for prokaryotic cells that havethe genetic potential for growth on O2 or NO3- to switch back and forthas needed.13) For each set of redox pairs given below, decide which compoundwould be the energy source (electron donor), which would be the electronacceptor, and what are the end products of the reaction.
Answer to Identify the role of oxygen in photosynthesis
A molecule in an excited electronic state must dissipate the extra energy in some way, and we can talk about different modes of "decay" of that energy to a lower electronic state (which does not necessarily have to be the ground state). There are three types of dissipation that can occur: "non-radiative," "radiative," and chemical reaction.
It is the initial electron releaser
The first point, then, is that photons are absorbed by molecules when their electronic spectra have strong absorption bands around the frequency of the incoming photon, as the chlorophylls do. In the process of "absorption" of a photon, a molecule is "excited" to a state of higher energy because an electron has moved from a ground state molecular orbital energy level to a higher energy level. Only certain transitions can occur, however, because the frequency corresponding to the energy difference must match the frequency of the photon. This is a statement of the energy conservation law and can be written as , and the peaks that you see in the absorption spectrum of a molecule correspond to the possible energy level differences that allow absorption of photons of corresponding frequency.
