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.
Cellular respiration 1. Cellular respiration. Typical eukaryotic cell. Cellular respiration is the set of the. metabolic reactions and processes that take. place in the cells of organisms to convert. biochemical energy from nutrients into. adenosine triphosphate (ATP), and then. release waste products.[1] The reactions. involved in respiration are catabolic.
