QUESTION 45 Which of the following statements is FALSE? Low oxygen levels in the blood increase respiratory rate. A decrease in the pH of blood increases respiration rate. An increase in the carbon dioxide in the blood causes pH to decrease. Higher brain centers can modify the activity of the respiratory center in the medulla oblongata. The Bohr effect allows carbon dioxide to bind more easily to hemoglobin that has released its oxygen.
