The partial oxygen pressure (pO2) should be high for the maximum loading of hemoglobin with the oxygen.
Hemoglobin is a quaternary protein that transports oxygen in the blood. Hemoglobin is made up of four heme subunits and an Iron atom. Blood oxygen is bound to the hemoglobin in red blood cells. One molecule of hemoglobin binds the four oxygen molecules and forms the oxyhemoglobin.
The partial pressure of the oxygen is an important factor that determines the binding affinity of oxygen to the hemoglobin. The higher the partial pressure of oxygen the more oxygen binds with the hemoglobin. The hemoglobin binds oxygen rapidly in the pulmonary capillaries of the lungs due to higher partial pressure of oxygen.

I would say this to be true
True. It works the
shoulders. However it can also work the
upper back muscles as well. It all
depends on the grip that you have.
Narrow grips work the upper back and shoulders while wider grips works
the shoulders. It all depends what you
want to develop with this exercise.
I'd say D because it doesnt matter what time of the day you consume alcohol you still drink the same amount.
