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.erobic respiration is the process most living things undergo to use food energy. Here we will investigate the definition, the steps of the process, what goes in and what comes out of the process, and the chemical formula. Get ready to breathe!
