One part of this process can be cyclic or non-cyclic, and its "Z-scheme" makes use of iron-sulfur proteins, P680 and P700 reaction centers, and plastoquinones. One molecule used in this process consists of pyrrole units surrounding a magnesium ion. Some species perform one part of this process via the C4 or CAM pathways, and RuBisCO catalyzes the Calvin cycle, also known as the "dark" part of this process. Water and carbon dioxide are converted into oxygen and sugars in this process using chlorophyll. For 10 points, name this process in plants
