Anyone here revising for GCSE’s 2021. At the moment England hasn’t cancelled our exams, so I figured it is best to keep watching these videos as they are so quick and understandable, especially as we are pressured to try and catch up on 6 months of missed school work. So Mr free science lessons guy you are an absolute legend 👏🏼👏🏼Thank you .

[@daniellenederpel916]

Gotta get ready for mocks on monday 🤞🤞
Edit-spoke to soon mocks pushed back bc someone went and caught the rona

Again, thank you.

[@zainabrahim6059]

Thank you so much!!!!!!!!

[@Yokshsjhsj]

im really confused in my textbook it mentions that Lactic acid +Oxygen ---> carbon dioxide + water. Is this correct? Very helpful video by the way!

[@plaguebf6632]

thats what happens when lactic acid is oxidised, so im assuming thats correct

[@TS-fn3lb]

That's anaerobic respiration. ( The process of respiring without the use of oxygen)

[@lukef1131]

that is how your body clears lactic acid from your muscles.

[@ao8127]

I have heard that his videos are based on the aqa GCSE Sciences spec. Can I still use this to revise if I am on the OCR GCSE Sciences spec?

[@magix33]

look at your exam board specification

[@honorscarborough7129]

So helpful thank you so much

I thought AQA will ignore the "Oxygen Debt"

yes
