Calvincirklo
Calvincirklo, also known as the Calvin Cycle, is a series of biochemical reactions that take place in the stroma of chloroplasts in photosynthetic organisms. It is the primary pathway for the fixation of carbon dioxide into organic compounds. The cycle does not directly require light, hence it is also referred to as the light-independent reactions of photosynthesis.
The Calvin Cycle begins with the enzyme RuBisCO catalyzing the carboxylation of ribulose-1,5-bisphosphate (RuBP) with carbon
For every three molecules of CO2 that enter the cycle, one molecule of G3P is produced as
