Photosynthetic photon flux density (PPFD)—the flux of light (usually expressed as micromoles per square meter per second [μmol m–2 s–1]) within the photosynthetically active range (400–700 nm).

The temperature dependence of the solubilities of O2 and CO2 is such that at higher temperatures, the ratio of O2 to CO2 in solution increases. In addition, the affinity of rubisco for CO2 decreases with increasing temperature, exacerbating its tendency to catalyze the wasteful oxygenase reaction, favoring the oxygenase reaction.
