As we examine the rate of enzyme function in vitro (that is, in the test tube or cuvette) remember that the conditions for this measurement may differ significantly from the enzyme's native environment in the cell. Identify two ways in which the cell's composition and internal environment may differ from our experimental conditions, and how these might impact the function of the enzyme (hint: think about the name of our enzyme)

Baroreceptors in the aortic arch and carotid bodies are mechanoreceptors that respond to the stretch that occurs in these arterial walls with changes in blood pressure. if pressure changes rapidly, the baroreceptors initiate a feedback mechanism that reduces blood pressure; however, if pressure changes slowly, as in developing hypertension, the receptors do not respond. given this information, the baroreceptors are most likely which type of receptor?
