Calculate the fractional saturation for hemoglobin when the partial pressure of oxygen is 40 mm Hg. Assume hemoglobin is 50%% saturated with oxygen at a partial pressure of 22 mm Hg and that the Hill coefficient is 3.

The fractional saturation for hemoglobin is 0.86

Explanation:

The fractional saturation for hemoglobin can be calculated using the formula

Where is the fractional oxygen saturation

is the partial pressure of oxygen

is the partial pressure when 50% hemoglobin is saturated with oxygen

and h is the Hill coefficient

From the question,

= 40 mm Hg

= 22 mm Hg

h = 3

Putting these values into the equation, we get

Hence, the fractional saturation for hemoglobin is 0.86.

most sediment washes or falls into the river as a result of mass movement and runoff. other sediment eroded from the bottom or sides of the river.
