Photosynthesis is a two-phase anabolic pathway in which light energy (sunlight) is converted into chemical energy. In photosynthesis, water, carbon dioxide, and sunlight is used to form glucose and oxygen. Photosynthesis can be carried to other organisms when the molecules are ingested as food. Cellular respiration is a catabolic pathway where organic molecules are broken down to release energy. In this reaction, organic molecules ... are broken down by oxygen which results in carbon dioxide and water. Cellular respiration is the opposite of photosynthesis. They form a cycle of where the prod...
