A kidney tubule cell takes in substances across its partially permeable cell membrane. Water moves into the cell from tubule fluid that is more dilute than the cell contents. Glucose moves into the cell from a lower concentration in the tubule fluid to a higher concentration inside the cell, using energy released by respiration.
Which pair of processes causes the movement of water and the movement of glucose?
Water: active transport; glucose: active transport
Water: active transport; glucose: diffusion
Water: osmosis; glucose: diffusion
Water: osmosis; glucose: active transport
