AS Biology - Oxygen dissociation curve (OCR A Chapter 8.4)

4 жыл бұрын

The oxygen dissociation curve shows how haemoglobin binds to oxygen (that's it really!). Its sigmoid shape shows haemoglobin's positive cooperativity behaviour. We can then look at the curve when the haemoglobin is in different situations (Bohr effect) or even as a different type of haemoglobin (fetal vs. adult), which show us if the haemoglobin is ready to bind to oxygen or to lose it.

thank you for your revision videos - they are very helpful!! i just wanted to say that there is correction needed when you say that c is where haemoglobin is fully saturated. this rarely happens as blood is fast flowing and most haem group are already occupied therefore its very difficult for oxygen to bind to the last haem group

Absolutely! In reality that is spot on, thanks for adding this on :)

what does 'shifting to the right/left' mean??

@bambobee7326 3 жыл бұрын

Why is the line for the ODC from b to c so steep? Isn’t it harder for the 4th oxygen molecule to bond to Hb after the 3rd. So shouldn’t it be flatter?

@charlottefern386 3 жыл бұрын

i think b represents the whole upwards bit of the curve not just that exact point
