Assume that the extracellular [Ca2+] = 1.2 mM and the intracellular [Ca2+] = 0.1μM. A.Calculate the equilibrium potential for Ca2+.B. If a channel were to open when Em=-50 mV, which way would Ca2+go?C. Is this a positive or negative current?

the answer would be a

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.

if it's not useful, feel free to report for mistake in answer.

you gotta add the following molecules so we can give u an answer

explanation:

it is b that is the answer.
