Question

All cells contain ion pumps that use the energy of ATP hydrolysis to pump ions across the plasma membrane. These pumps create an electrochemical gradient across the plasma membrane that is used to power other processes at the plasma membrane, including some transport processes. In animal cells, the main ion pump is the sodium-potassium pump. Complete the diagram below using the following steps. Drag the correct white label to the white target, indicating how many ions move through the pump and in which directions. Drag the pink labels to the pink targets, indicating the relative concentrations of Na^+ and K^+ inside and outside the cell. Drag the blue labels to the blue targets, indicating the relative charges inside and outside the cell.

Answer 1

Answer with explanation:

a. 3 sodium ions will move from inside to outside while 2 potassium ion will mover from outside to inside. This movement occur to maintain the gradient across the membrane

b. due to ion movement the concentration of sodium ions become higher outside the cell while the concentration of potassium ion will decrease

c. Due to 3 sodium ion movement outer change became positive (+).

d. due to ion movement the concentration of sodium ions become lower inside the cell while the concentration of potassium ion will increase inside

e. this change results in decrease in charge therefore charge inside the membrane becomes negative (-). See Solved Figure Attachment.
