Answer 1

The dark reaction of photosynthesis is also known as Calvin cycle, photosynthetic carbon reduction cycle, light-independent reaction, or synthetic cycle.

Explanation:

These are redox biochemical reactions which do not require sunlight, occur in three stages in the  stromal matrix of the chloroplast. Dark reactions utilize the light reaction products – ATP and NADPH (hydrogen ions and electrons)  to fix inorganic carbon dioxide by forming organic 3-carbon sugar molecules of glyceraldhehyde 3-phosphate (G3P). This is converted to glucose which the plant utilizes for performing all metabolic activities. Enzymes like RuBisCo, phosphoglycerate kinase, and dehydrogenase catalyses the reactions under this phase.
