Answer 1

The correct statement is that in the blood, oxygen is bound to hemoglobin, which carries it from the lungs to body tissues.

Step-by-step explanation:

The correct statement is: in the blood, oxygen is bound to hemoglobin, a protein found in red blood cells (RBCs). This is because hemoglobin is a metalloprotein in erythrocytes that carries oxygen from the lungs to the body's tissues. Oxygen diffuses from the alveoli into the surrounding capillaries, where it binds to hemoglobin. When it reaches body tissues, oxygen is released from hemoglobin and diffuses into the cells. Concurrently, carbon dioxide, which is produced as a waste product of cellular respiration within the tissues, diffuses from the body's cells into the capillaries and is then transported back to the lungs to be exhaled.
