Question

(b) Describe the characteristics of the interior of the aquaporin channel protein that allow water to flow through AND exclude glucose.
If isolated keratinocytes are placed in a hypotonic solution for 24 hours, explain the net direction of water movement AND why the

rate of water movement slows down over time.

Answer 1

Answer:

Aquaporin protein is a type of protein composed of a bundle of six transmembrane α-helices.

Explanation:

Aquaporin protein is a type of protein composed of a bundle of six transmembrane α-helices. These aquaporin protein have different size of water channels that allow water through to pass through it but it does not allow glucose to move through it due to its large size. The direction of water movement is toward the cell because there is low water inside the cell as compared to outside environment so the water moves inside the cell and  rate of water movement slows down over time due to filling of empty spaces with water.
