What protein does oxygen bind to in
red blood cells? (A) Hemoglobin, (B) histone, (C)
insulin, (D) globulin, (E) ironin.
The cells of our body need oxygen
in order to get energy from glucose in the food we eat by a process called cellular
respiration. This oxygen is inhaled into our
lungs when we breathe. Oxygen is carried by red blood
cells to deliver it to the cells in our body. These red blood cells contain a
special protein called hemoglobin. Hemoglobin can bind tightly to
oxygen and is what allows red blood cells to carry oxygen.
Therefore, the protein that oxygen
binds to in red blood cells is given by answer choice (A) hemoglobin.
