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.
What Cellular Respiration is. Cellular Respiration is the process where living organisms gathers the energy in food molecules to make energy. Heterotrophs, organisms that must get energy from food indirectly from sunlight or inorganic substances, go through the process of cellular respiration to get the energy needed. This energy comes from food. Heterotrophs, including humans and other animals, undergo Cellular Respiration, where the energy contained in food is released to make ATP, which provides cells with the energy needed to carry out the processes of life. Cellular Respiration takes place in a living body of a heterotroph.
