Which statement about the regulation of respiration is FALSE? Group of answer choices Respiratory centers in the medulla control the transition from inspiration to expiration. Carbon dioxide concentration is the most important chemical stimulus for regulating respiratory rate. Chemoreceptors in the walls of various arteries are sensitive to carbon dioxide levels in the blood. A group of neurons in the ventral medulla only become active when we need to breathe forcefully. Chemoreceptors may be sensitive to oxygen, carbon dioxide, and/or hydrogen ion concentration.
