Homework: Photosynthesis and Cellular pRespiration

In photosynthesis, CO2 and H2O are used to make glucose. The energy for this process comes from sunlight, where O2 is given off as a by-product since it needs CO2 than O2.

Respiration is basically the opposite of photosynthesis. Respiration breaks down glucose, using oxygen, and produces oxygen, and produces carbon dioxide and water. The energy that originally came from the sun is then made available to the organism.
