Final Biol 373 Review
A (even though technically blocks its not considered a blocker) - correct answer ✔✔Both norepinephrine
(NE) and phenylephrine, a drug
used as a decongestant, bind to alpha adrenergic receptors and elicit the same response. In this context,
NE is _____ of phenylephrine.
a. an agonist
b. an antagonist
c. an inhibitor
d. an agonist and blocker
e. an antagonist and competitor
c (low light sensitivity is achieved by rods - no rods in fovea) - correct answer ✔✔Which of the following
is/are true about the fovea?
a. Sensitivity in low light conditions is achieved by having many
photoreceptor cells at the fovea converge on a given ganglion cell.
b. It is densely populated with rods.
c. Receptive fields are very small.
d. a and c
e. a, b and c
ganglion cells - correct answer ✔✔in retina, action potentials are generated in
X is being reabsorbed - correct answer ✔✔if the clearance rate of X is less than the amount filtered, then
...
d - correct answer ✔✔In general, renal compensation for acidosis involves ...
a. secreting protons across the apical membrane into the tubular fluid.
b. secreting protons across the basolateral membrane into the interstitium.
