cellular respiration

... Extended Experimental Investigation Respiration Introduction: All living things respire. In fact, respiration is one of the most basic characteristics of living organisms so that if an object does not respire, it's not considered living. Respiration involves a complex series of chemical reactions where sugars are broken down to release energy by the use of oxygen. Respiration is the energy producing process of breathing, by which an organism supplies its cells with oxygen and relieves itself of carbon dioxide. The most effective way for cells to harvest energy stored in food is through cellular respiration, which is a metabolic process that captures the chemical energy from foods and converts them into ATP. The energy required to power living cells comes from the sun; plants capture this energy and convert it to organic molecules. In respiration, plants and animals convert glucose back into energy for growth. The chemical equation shows that the photosynthates from photosynthesis are
