Problem- A section of membrane with an aquaporin (AQP) has a water transport rate of about 2 billion water molecules per second (2 *10^9 molecules). Removal of the AQP lowers the rate to about 30 million water molecules per second (3* 10^7 molecules). By what factor does the aquaporin increase the rate of water transport in this example?
