A cell is placed in an isotonic solution. How does the cell maintain homeostasis in this environment? A. There is no movement of
water molecules into or out of the cell because the concentrations of solute particles inside and outside the cell are the same. B. Water will move across the cell membrane to the inside of the cell because the cell has a higher concentration of solute particles than the solution. C. Water will move across the cell membrane to the outside of the cell because the solution has a higher concentration of solute particles than the cell. D. Water will move across the cell membrane in both directions because the concentrations of solute particles inside and outside the cell are the same.
Answer: D. Water will move across the cell membrane in both directions because the concentrations of solute particles inside and outside the cell are the same.
<span>The protons want to diffuse into the mitochondrial matrix and they do this by going through the ATP synthase protein which resembles a water turbine. As the protons move through the ATP synthase, ATP is produced. In essence the energy from H+ wanting to diffuse through the inner mitochondrial membrane is converted to energy in the form of ATP</span>
