Question

Which ONE (OR MORE) of the following statements about the O 2 -Hb equilibrium curve is/are correct?

Accepted Answer

An increase in H +  concentration decreases affinity for oxygen.

Accepted Answer

A higher PO 2  means a higher % Hb saturation.

Answer

The lower the P50, the lower the O 2  affinity.

Answer

A steep lower portion of the curve aids O 2  diffusing into tissues.

Answer

The shape of the curve is linear allowing for an increased O 2  affinity.
