Answer:
1.During the process of photosynthesis, cells use carbon dioxide and energy from the Sun to make sugar molecules and oxygen. ... Then, via respiration processes, cells use oxygen and glucose to synthesize energy-rich carrier molecules, such as ATP, and carbon dioxide is produced as a waste product.
2.Photosynthesis is termed an endergonic reaction because it requires an input of energy in order to proceed. ... Without this energy, there would be no way for carbon dioxide, a small, simple molecule, to be converted to glucose, a considerably larger and more complex molecule.
