Q) Start with a photon of sunlight and a carbon atom in a molecule of carbon dioxide in the atmosphere: model/diagram their pathway from that starting point to their final destination as a glucose molecule that is used for energy in a cell in the plant root. Following your diagram/model, provide a written explanation for what your diagram/model depicts. Make sure both your model and explanation are clear, concise, and have the appropriate level of detail to clearly demonstrate you understand photosynthesis, cellular respiration, and the movement of mass and energy in plants.

Introduction
The major context for this lab is photosynthesis, and the overall equation for photosynthesis is:
12 H2O + 6 CO2+ light energy → C6H12O6+ 6O2+ 6 H2O

TRUE OR FALSE A coupled reaction is a pair of reactions, one exothermic and one endothermic. ATP contains less energy than ADP. In the ATP-ADP cycle, when the phosphate is removed, energy is released. In coupled reaction, an endothermic reaction supplies the energy needed to drive an exothermic reaction. Chlorophyll absorbs green light.arrow_forwardIt is biochemical reactions that enable organisms to harness sunlight to manufacture organic molecules?
