Four primary regions are the brainstem, the cerebellum, the cerebrum, and the cerebral cortex. Each brain region is responsible for a variety of functions, and injury to any of these regions impairs specific functions.
Cellular respiration is a pathway that organisms use to generate energy. Oxygen is required and is used to break down nutrients, like glucose sugar. The nutrients are broken down to generate ATP (energy) and carbon dioxide and water (waste). Organisms from all kingdoms of life can use cellular respiration including bacteria, archaea, plants, protists, animals, and fungi.
During aerobic respiration, oxygen is present, and helps the process to crank out energy very efficiently. Some organisms can also undergo anaerobic respiration, in which oxygen is absent and a somewhat less efficient method of metabolism takes place.ummary. What was built by photosynthesis, glucose, is broken down during aerobic respiration, releasing electrons in the process, which are crucial 'workers' in the manufacturing of ATP. During photosynthesis, the products of aerobic respiration are then taken in as reactants in building more glucose.
