Detailed explanation-1: -3. The light-independent reactions (Calvin cycle) use stored chemical energy from the light-dependent reactions to “fix” CO2 and create a product that can be converted into glucose.
Detailed explanation-2: -The light independent process (also called dark reactions or the Calvin-Benson cycle) takes place in the stroma of the chloroplast. Carbon dioxide is modified by series of chemical reactions to form carbohydrates. The energy for these reactions comes from ATP and NADPH generated during the light dependent process.
Detailed explanation-3: -The Light-Independent Reactions: Producing Sugars They occur in the stroma of thylakoids and are commonly called the Calvin cycle. Six carbon dioxide molecules from the atmosphere enter the Calvin cycle and combine with 5-carbon compounds already present. They produce twelve 3-carbon molecules.
Detailed explanation-4: -ATP and NAPDH are used in the light-independent reactions of photosynthesis to fix CO2 into carbohydrate; a reaction catalysed by ribulose-1, 5-bisphosphate carboxylase oxygenase (RUBISCO). Fixed carbohydrate is then used for all cellular functions, including respiration, biomass generation and lipid synthesis.
