    Assume that an actively respiring cell has 3x number of K+ in its cytoplasm and 2x number of K+ outside. After some time, x number of K+ entered into the cell. What is the process by which K+ transport has taken place?

    A)  Primary active transport

    B)                  Secondary active transport

    C)                  Diffusion

    D)                  Passive transport
