Question

Which statement is true concerning blood cells?<br /><br />a. white blood cells take oxygen to body tissue.<br />b. red blood cells contain a protein that binds with oxygen.<br />c. white blood cells contains a protein that releases oxygen.<br />d. white blood cells contain hemoglobin

Answer 1

The correct answer is b. All the other answers suggest that white blood cells are involved with the transportation of oxygen, whereas this is the job of red blood cells.

Answer 2

Answer: b. red blood cells contain a protein that binds with oxygen.

Explanation: Each RBC contains millions of molecules of hemoglobin, a complex protein designed to bind and release oxygen. When hemoglobin binds with oxygen, it’s called oxyhemoglobin. RBCs take oxygen to body tissues, where the oxygen is released. As the tissues use oxygen, they produce the waste product carbon dioxide, which is picked up by more RBCs and brought back to the lungs for release out of the body via exhalation... PF
