Document Summary
All three are hexose with 6 carbons ( Predict the energy content of sugar: a sugar should have (blank) energy content compared to a fatty acid with the same number of carbon. Burning of sugars with oxygen produces energy-poor waste products like carbon dioxide and water. Cellular respiration combines with h electrons to form 2. Photosynthesis extracts electrons from water. to 4+ 4 electrons + Solar energy is harnessed through photosynthesis by producers (plants, algae, and photosynthetic bacteria); all consumers rely on energy rich molecules (c-h bonds) synthesized by producers. Atp is produced not only in cellular respiration, but also as an intermediate in sugar production in photosynthesis. Atp is too unstable to serve as an actual storage form of energy. So, sugars are used for energy storage and transfer in plants. Sugars exist in the cell as rings. Sugars have to be transformed into atp in order to do work.
