Asingle na+/k+ atpase pump is present in the plasma membrane of an artificial cell with an initial cellular environment of 1000 molecules of na+ and 1000 molecules of atp inside the cell, 1000 molecules of k+ outside the cell, and a net charge differential across the plasma membrane of 0. assuming the only changes in the cellular environment are a result of the pump's actions, what would be the number of na+, k+ and atp molecules inside the cell after 100 cycles of the pump and what would be the net charge differential (inside-outside) across the plasma membrane?

Imagine that a new planet is discovered with two moons of equal mass: moon a and moon b. the mass of the new planet is greater than the combined mass of its moons. moon a is farther away from the new planet than moon b. what is the planet's gravitational pull on moon a compared to the planet's gravitational pull on moon b? the planet's gravity repels moon a with a greater force than it repels moon b, which is why moon a is farther away. the gravitational pull on moon b is greater than on moon a because moon b is closer to the new planet than moon a. the gravitational pull on moon b is greater than on moon a because moon b is farther away from the new planet than moon a. the gravitational pull on moon a is the same as the gravitational pull on moon b because distance does not affect the planet's gravity.
