Because both reduction and oxidation are occurring simultaneously, this is known as a redox reaction. An oxidizing agent is substance which oxidizes something else. In the above example, the iron (III) oxide is the oxidizing agent.Photosystem is the form of pigments on the thylakoid membrane1. It collects energy over the wavelengths and concentrates it to one molecule which uses the energy to pass one of its electrons on to a series of enzymes1. Photosystem II occurs with two series of enzymes followed by Photosystem I in order to create energy for a plant1.In general the more reduced an organic molecule is, the more energy is released when it is oxidized to \(CO_2\). Going back to our single-carbon examples, we see that methane, the most reduced compound, releases the most energy when oxidized to carbon dioxide, while formic acid releases the least:H is -1, C is 0, O and S are +1. Count each bond, so a double bond to O is +2. Then add up the oxidation states of each carbon to get the oxidation a state of the entire molecule.
