Detailed explanation-1: -When a glucose molecule is assembled during photosynthesis, the process takes up 12hydrogen ions from the stroma of the chloroplast. What process adds 12 hydrogen ions to the chloroplast? A 6 water molecules splitting apart during the light-dependent reactions.
Detailed explanation-2: -The chemical equation for photosynthesis is 6CO2+6H2O→C6H12O6+6O2. 6CO2+6H2O→C6H12O6+6O2. In plants, the process of photosynthesis takes place in the mesophyll of the leaves, inside the chloroplasts.
Detailed explanation-3: -The carbon atoms used to build carbohydrate molecules comes from carbon dioxide, the gas that animals exhale with each breath. The Calvin cycle is the term used for the reactions of photosynthesis that use the energy stored by the light-dependent reactions to form glucose and other carbohydrate molecules.
Detailed explanation-4: -During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose.
Detailed explanation-5: -The chemical formula for glucose, a simple sugar, is C6H12O6. When a glucose molecule is assembled during photosynthesis, the process takes up 12 hydrogen ions from the stroma of the chloroplast.
