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.
Organisms capable of photosynthesis produce food molecules like carbohydrates. There are many forms of cellular respiration. Some organisms require oxygen to carry out respiration known as aerobic cellular respiration and the respiration that does not require presence of oxygen is called anaerobic cellular respiration.ellular respiration is a series of set of metabolic reactions and processes. These reactions takes place in the cells of organisms, where the organisms convert biochemical energy from nutrients into adenosine triphosphate.
