Biochemistry the phase of photosynthesis in which glucose is produced from carbon dioxide, using ATP and NADPH formed by the light reaction (cf. light reaction n. at light n.1 Compounds 3); any of the chemical reactions that occur in this phase.Although not dependent on energy derived from light, this phase does require light for the activation of enzymes involved in its reactions. ΚΠ 1919 Ann. Bot. 33 518 Though certain stages in the complex chain of reactions of carbon assimilation are certainly photochemical, yet other subsequent stages are ‘dark reactions’. 1982 M. J. Dring Biol. Marine Plants iii. 44 Photosynthesis must consist of two distinct processes: a photochemical process (or ‘light reaction’) influenced primarily by irradiance and chlorophyll concentration; and an enzymic, chemical process (the ‘dark reaction’). 2018 Proc. National Acad. Sci. U.S.A. 115 9334/1 We know that the division of photosynthesis into light and dark reactions is inadequate because the activity of a number of chloroplast enzymes..is strictly controlled by light. < as lemmas |
