Similar to what you studied in skeletal muscle cells, the resting chemical disequilibriumof myocardial cellsis maintained by sodium-potassium pumps in the cell membrane. however, myocardial cells must also have these transporters in the cell membrane to return to the pre-activatedstate.

Which statement about relative potential energy of electrons is correct? a. an electron in the 2 p orbital of the second electron shell has more potential energy than an electron in the 2 s orbital of the second electron shell. b. an electron in the 2 p orbital of the second electron shell has more potential energy than an electron in the 3 p orbital of the third electron shell. c. an electron in the 3 p orbital of the third electron shell has more potential energy than an electron in the 2 p orbital of the second electron shell.
