The oxygenase activity of rubisco produces one molecule each of 3-phosphoglycerate and 2-phosphoglycolate due to this activity a loss of carbon fixed by the Calvin–Benson cycle and yields 2-phosphoglycolate which is a inhibitor of two chloroplast enzymes known as;

German scientist Adolf Fick discovered that the rate of diffusion is directly proportional to the concentration gradient (∆cs /∆x)—that is, to the difference in concentration of substance s (∆cs ) between two points separated by the distance ∆x. According to Fick’s first law,

Plant cells have several internal compartments, each of which can differ in its ionic composition. The cytosol and the vacuole are the most important intracellular compartments that determine the ionic relations of plant cells, Ion concentrations in the cytosol and the vacuole are controlled by passive (dashed arrows) and active (solid arrows) transport processes

Nitrate transport is an example that is of interest not only because of its nutritional importance, nitrate is negatively charged, and such an electric charge imposes an energy requirement for the transport, Mutants in nitrate transport or nitrate reduction can be selected by growth in the presence of chlorate, Chlorate is;
