Answer:
8 b. K moves into the cell by passive transport.
9. D. K movement out of the cell requires ATP hydrolysis.
Explanation:
Passive transport is a type of transport in which molecules moves from a region of lower concentration to the region of higher concentration through a semipermeable of the cell without the use of energy. So potassium moves into the cell without the use of energy but its movement outside the cell requires energy in the form of Adenine tri phosphate (ATP).
