WebWhat best describes the roles of photosystem I and photosystem II in the process of photosynthesis? answer choices They absorb sunlight and transfer the energy to electrons. They form ATP as hydrogen ions cross the thylakoid membrane. They absorb sunlight and distribute the energy as heat. Web2) In many situations phosphate is a limiting nutrient, so needing to make more ATP could severely limit the plants ability to store energy. 3) Fixed carbon (e.g. glucose) can be converted into other molecules the plant needs including: • cellulose for structure • lipids for long term energy storage, cell membranes, etc.
