The bohr shift on the oxygen-hemoglobin dissociation curve is produced by changes in a. temperature b. the partial pressure of carbon monoxide c. hemoglobin concentration d. the partial pressure of oxygen e. ph

The attached picture is a typical look of a standard oxyhemoglobin dissociation curve. The shift of the curve is affected by a change in the concentration of the hydrogen ion, or simply, the pH. This is called the Bohr effect. As pH increases, the curve shifts to the left. Otherwise, it shifts to the right. So, the answer is letter e.

The closer the atoms are to becoming ionic the more highly dense the negatively charged side gets.
