You explain things so well and clear, so much better than my stupid lecturer at university who can't explain anything. Thank you very much for this helpful video :)
It was a great video. I like the way how Sal Khan started with black screen. Believe me or not, I can't learn anything from youtube unless there is black screen.
if your PCO2 is increased, wouldn't this was cause a decrease in pH? Therefore a rightward shift would be caused by an increase in PCO2 and a decrease in pH.
you're correct, an increase in PCO2 leads to a decrease in pH. whether or not this causes or right or leftward shift in the dissociation curve depends on whether you are talking about the partial pressure of CO2 in the blood or in the tissues. an increase in PCO2 in the tissues (which i reference in the video) would decrease the affinity of oxygen for hemoglobin in the blood, and therefore facilitate its unloading into the tissues, corresponding with a rightward shift. an increase in pCO2 in blood, on the other hand, would lead to a leftward shift.
I love your video! HOWEVER I feel you're missing an important detail - that while an increase in any CADET shifts the curve right it also decreases O2 unloading to the tissues. Likewise a shift of the curve to the left (decrease in any CADET) will decrease affinity, but O2 unloading to the tissues will increase. Great video in any case! You have one more subscriber!;-)
I use a free app from the Apple Store called Sketchbook Express, my hardware is a Wacom Bamboo tablet, and I do the screen recording and editing with Camtasia.
