If baroreceptors are generating more and more action potentials per second, then you would expect:
Homework Answers
The baroreceptors are sensory receptors located in the arteries of the neck and the thorax, including the aorta. They are sensitive to stretching forces and as such are receptive to changes in blood pressure. For example, Arterial baroreceptors trigger an increase in sympathetic activity and a decrease in parasympathetic activity, which brings about increases in heart rate, myocardial contractility, and vascular resistance. The norepinephrine constricts blood vessels and raises the heart’s rate and pump strength to drive up blood pressure.
The stimulated baroreceptors of arch of aorta and carotid sinus send signals to cardiovascular center of CNS. Now the cardiovascular center reflexes the signal to SA and AV nodes by stimulating the norepinephrine.
Thus, the correct option is (C).

Ion channels are involved with generating action potentials. Below is an electrical profile of a neuronal action potential. In the boxes below list whether the channels are all open, all closed, opening, or closing at each of the letters shown in the profile. (Opening implies that channels were "all closed" and are moving toward their "all open" state. Closing indicates the opposite. Use the term "closing" to represent the inactivated state of the Na+ channels.) (7 pts) 1. Channel Type...

In which assay would you expect that EDTA, added to block the action of proteases, to be an interfering substance? In which assay would you expect DTT, added to reduce disulfide bonds, to be an interfering substance? ( I said Buriet assay for both because both EDTA and DTT dont contain any polypeptides backbone chain so the Buriet assay won't be able to detect anything? )
