____ is a passive transport plasma membrane protein that forms a pore through which water (but not solutes)can flow freely across the membrane.
A) ADH
B) A sodium ion
C) Ketone bodies
D) Aquaporin
E) Angiotensinogen

____ is a passive transport plasma membrane protein that forms a pore through which water (but not solutes)can flow freely across the membrane.  
A) ADH
B) A sodium ion
C) Ketone bodies
D) Aquaporin
E) Angiotensinogen

Quizplus · Accepted Answer

Aquaporin is a type of passive transport plasma membrane protein that allows the free movement of water molecules across the membrane, while preventing the passage of solutes. It is an important protein for maintaining water homeostasis in cells and tissues. ADH, sodium ions, ketone bodies, and angiotensinogen are not directly involved in this function.
