The Correct Answer and Explanation is:
Correct Chemical Equation for Photosynthesis:
✅ 6CO₂ + 12H₂O + sunlight → C₆H₁₂O₆ + 6O₂ + 6H₂O
Correct Answer for Products of the Light Reactions Used in the Calvin Cycle:
✅ ATP and NADPH
Explanation:
Photosynthesis is a fundamental biological process through which green plants, algae, and some bacteria convert light energy from the sun into chemical energy stored in glucose. This process primarily occurs in the chloroplasts of plant cells and can be represented by the overall balanced chemical equation:
6CO₂ + 12H₂O + sunlight → C₆H₁₂O₆ + 6O₂ + 6H₂O
This equation shows that six molecules of carbon dioxide and twelve molecules of water, in the presence of sunlight and chlorophyll, produce one molecule of glucose (C₆H₁₂O₆), six molecules of oxygen (O₂), and six molecules of water. The oxygen is released as a byproduct into the atmosphere, while the glucose is used as an energy source for the plant.
Photosynthesis occurs in two stages: the light reactions and the Calvin cycle (also known as the dark reactions or light-independent reactions).
Light Reactions take place in the thylakoid membranes of the chloroplasts. During this stage, sunlight is absorbed by chlorophyll, which excites electrons and drives the production of two high-energy molecules: ATP (adenosine triphosphate) and NADPH (nicotinamide adenine dinucleotide phosphate). Water molecules are also split (photolysis), releasing oxygen gas as a byproduct.
Calvin Cycle occurs in the stroma of the chloroplast and does not require light directly. It uses the ATP and NADPH produced in the light reactions to convert carbon dioxide into glucose through a series of enzyme-mediated steps. Thus, ATP provides the energy, and NADPH provides the reducing power (electrons) needed to synthesize glucose.
In summary, the correct chemical equation shows the true stoichiometry of photosynthesis, and the ATP and NADPH produced in the light reactions are essential to power the Calvin cycle and complete the photosynthetic process.
