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 Both plants and animals carry out cellular respiration. Cells in both plants and animals contain organelles called mitochondria that are the sites for the cellular respiration process. Cellular respiration uses glucose and oxygen and produces carbon dioxide, water, and energy stored in ATP molecules. The energy stored in ATP is used to power. and organismâs life activities such as circulation, excretion, movement, and synthesis.
