Document Summary

Compare and contrast the structures involved in photosynthesis. Widen the spectrum of light that can be absorbed. Photosynthesis is the process in which light energy is converted to chemical energy in the form of sugars. In a process driven by light energy, glucose molecules (or other sugars) are constructed from water and carbon dioxide, and oxygen is released as a byproduct. The glucose molecules provide organisms with two crucial resources: energy and fixed organic carbon. energy can be harvested through processes like cellular respiration and fermentation, which generate adenosine triphosphate . Atpatpa, t, p, a small, energy-carrying molecule for the cell"s: fixed carbon. Carbon from carbon dioxide inorganic carbon can be incorporated into organic molecules; this process is called carbon immediate energy needs: energy. The glucose molecules serve as fuel for cells: their chemical fixation, and the carbon in organic molecules is also known as fixed carbon.
