Biology

babunello [35]3 years ago

Water diffusion is called osmosis. Oxygen is a small molecule and it's nonpolar, so it easily passes through a cell membrane. Carbon dioxide, the byproduct of cell respiration, is small enough to readily diffuse out of a cell. Small uncharged lipid molecules can pass through the lipid innards of the membrane.

Which of the following statements best defines the oxygen-hemoglobin dissociation curve?a) a graphical representation of the amo
saul85 [17]

Answer:

b) a graphical representation of the relationship between hemoglobin's percent saturation and the partial pressure of oxygen

Explanation:

On vertical axis-hemoglobin's oxygen saturation

On horizontal axis-oxygen partial pressure

This curve determines hemoglobin affinity for oxygen. If hemoglobin has high oxygen saturation, hemoglobin's affinity for oxygen is high.

As the blood moves through the systemic capillary, hemoglobin's affinity for oxygen decreases, so that oxygen can be released into the cells.
