Question

Which of these statements is true with regard to this animation? which of these statements is true with regard to this animation? sodium and potassium ions are transported against their concentration gradients. the cell is not expending energy. sodium ions are transported down their concentration gradient. potassium ions are transported down their concentration gradient. the cell does not expend atp?

Answer 1

The animation probably giving an explanation about Na/K-ATPase pump in cells. This pump will move sodium and potassium ion against their concentration. Sodium will be sent out and potassium is sent in. But this pump using energy which was expressed as ATP. Then, the answer to this question would be: 
sodium and potassium ions are transported against their concentration gradients
