Which of these influences the oxygen hemoglobin saturation dissociation curve? temperature, ph, bpg, or all of the above.
00:11
So it's all of the above, and the curve that we're talking about here looks something like this.
00:19
So this is the curve for the partial pressure of oxygen and the percentage of oxygen saturation on the hemoglobin.
00:28
And the point of this question is that this curve can be shifted, so it can shift left or right.
00:37
So it can shift left, so it comes over here, and that means that for the same partial pressure oxygen, you have a greater saturation, so increases affinity.
00:52
So left shift increases affinity for oxygen, right shift decreases, decreases it, and the factors that can influence that are temperature, ph, and the bpg.
01:11
So a left shift means that we are getting higher ph, so higher ph, and a lower temperature, and a lower bpg...
