Definition

noun

The series of biochemical reactions in photosynthesis that do not require light to proceed, and ultimately produce organic molecules from carbon dioxide.


Supplement

The energy released from ATP (produced during the light reactions) drives this metabolic pathway. It is described to be light-independent as it proceeds regardless of the amount of light available. The term is used in contrast to light-dependent reaction of photosynthesis that as the name implies depends on and requires light to take place.
