Question

question 7
hemoglobins affinity for oxygen would be decreased, shifting the oxygen dissociation curve to the right, under all of the following conditions except:
a ph increases
b temperature increases
c co₂ increases
d h⁺ increases
question 8
which of the following structures is considered anatomic \dead space\?

Explanation:

The oxygen - dissociation curve shifts to the right when hemoglobin's affinity for oxygen is decreased. This occurs under conditions such as increased temperature (B), increased \(CO_2\) (C), and increased \(H^+\) (D). Increased \(H^+\) (lower pH) causes a right - shift (Bohr effect). However, when pH increases (more alkaline), hemoglobin's affinity for oxygen increases, causing a left - shift of the oxygen - dissociation curve.

Answer:

A. pH increases
