Question

The Amount of 02 normally carried by 100 ml of pure blood, is
A. 40 ml
B. 10 ml
C. 20 ml
D. 30 ml

Answer 1

In the event that one starts with a deoxygenated test of blood and permits it to equilibrate in ventures with gas combinations of expanding $PO_2$, the coupling locales for oxygen will turn out to be continuously involved until, at a sufficiently high $PO_2$, every one of them will contain oxygen.

Complete answer:
Oxygen is conveyed in the blood either in disintegrated structure or in a relationship with haemoglobin. Be that as it may, to ascertain the convergence of oxygen moved in the blood, one has to comprehend the measure of oxygen conveyed by every gram of haemoglobin. In an immersed condition, one gram of haemoglobin conveys 1.34 ml of oxygen. Regularly 100 ml of blood has around 15 gm of haemoglobin in it. In this way, the measure of oxygen conveyed in 100 ml of unadulterated blood can be determined as $15 \times 1.34$ ml = 20 ml.

Additional information:
The haemoglobin particle has four restricting destinations for oxygen atoms: the iron iotas in the four heme gatherings. In this way, every Hb tetramer can tie four oxygen particles. From the sub-atomic load of Hb, one can compute that 1 g of Hb can consolidate with 1.39 ml of oxygen. As a matter of fact, a portion of the Hb typically in red platelets can't scrape oxygen (it is either metHb or HbCO), and the experimentally decided oxygen-restricting limit of haemoglobin (CHb) is 1.34 ml $O_2$ per gram Hb. In 100 ml of blood, there is around 15 g of Hb, so 100 ml of blood has the ability to tie 20.1 ml of oxygen. This amount is known as the oxygen-restricting limit of blood (CB). Note that CB is relative to the hematocrit of the blood.
So the correct answer is 20 ml.

Note:
A bend speaking to the balance authoritative of $O_2$ to blood has appeared. The bend is known as the oxygen immersion bend or the oxygen separation bend and communicates the connection among $PO_2$ and the bound oxygen content.
