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

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.

This video helped me sooo much (eventhough I do AQA Biology)

[@naomisja9385]

Thank u for ur video ☺️😗

[@sarojinibeharry928]

Completely helpful! Awesome

[@BioRach]

Glad you found it helpful! Thanks for watching :D

[@alizehzaib109]

extrmely helpful

[@Sara-sc6nm]

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

[@BioRach]

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

[@ay7565]

Super helpful thank you so much

Thank you so much 😭😭

[@BioRach]

Haha thanks for watching! :)

[@rahh8222]

hey would it be wrong if i said for anaerobic respiration instead of aerobic respiration

[@kelisa4894]

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

[@sapphire9133]

hello miss, not related to video but what pens do you use?

[@bambobee7326]

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]

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

[@lmj9517]

and all that Biology!

[@rosieosabutey1448]

That one person that disliked. I-

[@givebread8279]

subtitles at 6:12 pahahah

[@natalietwal6245]

LMFAOO

[@enacausmembrane]

Thank You for this explanation, I finally got it.

Correction the hb in the tissue is called deoxy hb. Not oxy
