Summary Introduction
Introduction: The Calvin-Benson cycle is also called as light-independent reactions. The energy for this cycle is not taken by sunlight instead the energy is gained from NADPH and ATP. As a result of this reaction, the sugar molecules are formed at the stroma of the chloroplast. The end product of this reaction is 2 glyceraldehyde-3-phosphate molecules, 3 ATP and 2 NADP+ molecules.
