Question

Short description of Calvin cycle.
whosoever will answer will be marked as branlist.

Answer 1

Calvin cycle is the cycle of enzyme-catalyzed dark reactions of photosynthesis that occurs in the chloroplasts of plants and in many bacteria and that involves the fixation of carbon dioxide and the formation of a 6-carbon sugar.

Answer 2

The Calvin cycle is also sometimes referred to as the “light independent” reactions of photosynthesis, since it is not powered directly by photons from the Sun. Instead, the Calvin cycle is powered by ATP and NADPH, which are created by harnessing the energy from photons in the light-dependent reactions.

Function of the Calvin Cycle

The function of the Calvin cycle is to create three-carbon sugars, which can then be used to build other sugars such as glucose, starch, and cellulose that is used by plants as a structural building material. The Calvin cycle takes molecules of carbon straight out of the air and turns them into plant matter.

This makes the Calvin cycle vital for the existence of most ecosystems, where plants form the base of the energy pyramid. Without the Calvin cycle, plants would be unable to store energy in a form that herbivores could digest. Carnivores would subsequently not have access to energy stored in the bodies of herbivores!
