Calculate the fractional saturation for hemoglobin when the partial pressure of oxygen is 58 mm hg. assume hemoglobin is 50% saturated with oxygen at a partial pressure of 28 mm hg and that the hill coefficient is 3. express your answer to two significant figures.

0.8988

Explanation:

To calculate the fractional saturation of hemoglobin , the formula used is

YO_2=

now putting the values

YO_2=

=

=0.8988

Therefore, fractional saturation of hemoglobin= 0.8988

where

YO_2= fractional saturation of hemoglobin

pO_2= partial pressure of oxygen

p50= is the pO_2 at which hemoglobin is 50% saturated

  the   balanced   equation   for   reaction of   ca metal   with   o2 to   produce   cao   is as below

2 ca+ o2→ 2 cao2

  explanation

the reaction is   balanced     since the   number of atoms   in reactant side is   equal to   number of atoms   in   product side.   for   example   they   are 2   atom of   ca in   reactant   side   and   2   atoms of ca   in   the product side.

  the   process   is a   meet the   requirement   of   redox   reaction because :     calcium   is   oxidized   from   oxidation state 0   to 2+   while   oxygen   is reduced from   oxidation   state   0   to 2-
