A Level Biology Revision "Haemoglobin and the Oxygen Dissociation Curve"

You can find all my A Level Biology videos fully indexed at www.freesciencelessons.co.uk/...
In this video, we look at the role of haemoglobin in transporting oxygen. First we explore how erythrocytes (red blood cells) are adapted for oxygen transport. We then look at the structure of haemoglobin and how haemoglobin binds reversibly to oxygen. Finally, we explore the oxygen dissociation curve for haemoglobin and look at how oxygen binding shows positive cooperativity.

Thank you for helping me get through my chemistry gcse papers! Absolute lifesaver

Thank you for helping me get through my chemistry gases papers! Absolute lifesaver when I get in year 10

[@sariah7641]

this is a level not gcse😭

[@anonymous-fp1jx]

Hi, would we need to know about the adaptations to the red blood cells for efficient transport for the AQA spec a level?

[@endcreepstudios5981]

I'm doing my gcse mocs tomorrow and i really want to revise but i don't know how i can revise easily and with less stress and boring things how would i go about doing this?

[@Ayyan-e6x]

Are the haemoglobin in red blood cells only 97% saturated in the alveoli?

[@duck5332]

thanks!

[@samnewmarch06]

When do you propose to finish all videos on the A level biology syllabus?

[@Freesciencelessons]

I'm aiming to finish all of the A level videos by the end of 2023.

@@Freesciencelessons great thanks!

hi right now im in year 10 and i do higher tier science.science is one of my strong subjects and i revise it all the time i was wondering what you would tell me to revise right now to prepare for y11 i do aqa btw

[@Freesciencelessons]

I would recommend revising the videos on my website (freesciencelessons.co.uk) as they're easier to find in order. Make sure that you are very happy with the Year 10 material before you look at the Year 11 work.

Hello FSL
I’d like to ask you to make a Polymers video for GCSE please I have an exam soon

[@Freesciencelessons]

Hi. There are several of them already. If you search my channel for "polymers", you'll find them.
