Document Summary
In almost all ecosystems, energy ultimately comes from the sun. Come of the energy in sunlight is captured by chloroplasts. Atoms of carbon dioxide and water are rearranges. Sugar is broken down to carbon dioxide and water. Cellular respiration takes place in the mitochondria of eukaryotic cells. In these energy conversions, some energy is lost as heat. Respiration, as it relates to breathing, and cellular respiration are not the same. Respiration, in the breathing sense, refers to an exchange of gasses. The cell captures some of the released energy to make atp organism brings in oxygen from the environment and releases waste co2. Cellular respiration is the aerobic (oxygen-requiring) harvesting of energy from food. Cellular respiration is an exergonic (energy-releasing) process that transfers energy from molecules by cells the bonds in glucose to form atp. The quantity of heat required to raise the temperature of 1 kilogram (kg) of water by 1 c.
