Researchers have long attempted to find a substitute for red blood cells,specifically the hemoglobin carrying ability.With the low but possible risk of disease transfer from blood transfusion,such a synthetic substance could be guaranteed safe if it was effective.Which of the following properties would be important for "artificial red blood cells"?
A)must attach to and never release oxygen
B)must release oxygen to any other medium despite concentration gradient
C)would bind to iron molecules already bound to other artificial blood units
D)must provide the clotting reaction
E)would bind to oxygen in a high oxygen concentration solution and release oxygen when in a low oxygen concentration solution

Question

Quizplus · Accepted Answer

The artificial red blood cells should be able to bind to oxygen in high concentration solutions and release oxygen when in a low oxygen concentration solution, just like natural red blood cells. This property is essential for effective oxygen transportation in the body. Options A, C, and D are not relevant to the oxygen-carrying ability of red blood cells, and option B contradicts the purpose of oxygen transportation.
