Hemoglobin molcules account for more than 95 percent of Erythrocyte's proteins.
There are approx. 280 million moleules of hemoglobin in each RBC. hemoglobin also carries about 23 percent of carbon dioxide transposted in the blood.. And the bindings of amino acids to carbon dioxide or globin subunits is reversable

How much liquid in iv blood bag?
Typically when people refer to a blood bag they mean a transfusion of packed red blood cells. A transfusion of one unit of packed red blood cells would be approximately 250 mL.
What is packed rbc?
Packed red blood cells (PRBCs), also called "packed cells," are a preparation of red blood cells that are transfused to correct low blood levels. A unit of PRBCs begins as a 450 milliliter volume of whole blood. Platelets and plasma are removed to leave a preparation of 220 milliliters of mostly red blood cells. This step concentrates the red blood cells so that they occupy less space, thus the term "packed." One unit of PRBCs typically will raise the hematocrit by 3-4% and the blood hemoglobin concentration by 1 gm/dl. PRBCs last in refrigeration for up to 42 days, but under the right conditions, they can be frozen for up to a decade.
How many cc in a unit of packed red blood cells?
It depends. There is no set amount of cc in each unit of blood. The institution I work for handwrites on each of the labels exactly how many cc are in that particular unit. The number is always very random (i.e.219, etc.) There are typically between 250&350cc per unit.
What are the four components that can be derived from a unit of blood?
AHF, white blood cells, red blood cells, and hemoglobin.
How many liters is equal to 1 unit of blood?
This question needs more information. 1 unit of blood can be a couple of different things. It could be whole blood or packed cells. I will assume whole blood is what is being asked. A unit of blood is never the same. It is approximately 450 ml's. So your answer would be simply 0.45 liters. As a nurse, I have hung hundreds of units of blood for patients and they are all different. We record the amount of volume in each bag when given to a patient. But typically blood given to patients is given in components. They are given either packed cells which are just the red cells to transport oxygen or they are given plasma for volume or platelets for clotting factors. Typically the blood is spun at the blood bank and separated out. Depending on the volume of packed cells spun off is how much is given to patients in the hospital.
How long does it take to transfuse packed red blood cells?
It depends on the scenario, PRBC infusers can infuse 1 unit in 5 minutes in trauma settings with acute blood loss while people who have CHF and are at risk volume overload it can take as long as 2-3 or more hours to infuse 1 unit.
Are the basic unit of all living things?
Yes, cells are the basic unit of all living things. WEithout cells every living thing would die because, the cells in our bodies produce blood. We all need blood to live.

How much blood is in one donated unit?
This depends on various factors and the volume of blood in each unit bag will not always be the same from one bag to another. Blood banks usually mark each bag individually with its specific measure of volume in mL. Whole blood units are usually around a pint or a bit over 450 mL Packed blood cells are usually around a half pint. According to the FAQ on the Gulf Coast Regional Blood Center web site, a unit is one pint, which equals about 473 mL. Approximately 450mL according to Canadian Blood Services.
How do doctors check how much blood you have in your body?
Doctors don't check how much blood you have in your body. They do a best guesstimate based on size and weight. Some lab tests check the relative and absolute numbers of blood cells per unit volume.
How many milliliters in a 30 unit insulin syringe?
A 70 years old client is admitted to the hospital with lower GI bleeding. His hemoglobin on admission is 7 g/dl. The doctor orders 2 units of packed red blood cells to infuse over 2 hours each. The blood administration set has a drip factors of 10gtt/ml. How much flow rate should you regulate the blood?
What are four components that can be derived from a unit of blood?
If I am reading the question right, answer; plasma, serum, red cells, white cells.
