Unformatted text preview: normal besides slightly lower pH. What could be the consequences in respect to respiration? a) Peripheral and central chemoreceptors will decrease firing frequency, eventually decreasing ventilation b) Peripheral and central chemoreceptors will increase firing frequency, eventually increasing ventilation. c) There will be no change in respiration. d) Peripheral chemoreceptors will increase firing frequency, which will lead to an increase in ventilation. e) All above answers are incorrect. Correct answers: 1. b. 2. d. Central chemoreceptors are sensitive to pH in the brain extracellular fluid due to diffusion of CO2 (not the hydrogen ions) through blood brain barrier....
