< Question 6 of 14 > O Macmillan Learning A section of membrane with an aquaporin (AQP) has a water transport rate of about 3 billion water molecules per second 3 x 10 molecules-s-¹). Removal of the AQP lowers the rate to about 40 million water molecules per second ( 4.0 x 107 molecules-s-¹). By what factor does the aquaporin increase the rate of water transport in this example? Note that this is a hypothetical situation, and does not reference any specific data or study. However, 3 x 10° molecules/s is a common estimate given for flow through an AQP. Water flow through an AQP is often stated in terms of a water permeability coefficient with units of centimeters per second. The actual value varies with osmotic pressure and type of AQP, among other factors. Some studies have shown around a 10-fold decrease in water permeability after AQP removal. factor increase:
