In this video, we look at anaerobic respiration. First we explore why a lack of oxygen prevents the production of ATP. We then look at how this is partially solved by anaerobic respiration in mammals (producing lactic acid or lactate) and in plants and yeast (producing ethanol).
im terrified for paper 3 today, thank you for your videos :)
Is fermentation and anaerobic respiration the same thing?
If we're talking about yeast, then yes. The word "fermentation" is sometimes used quite casually to refer to different reactions.
Could you make some videos on genetics for a level ?
do we have to know the enzymes which catalyse the conversion of pyruvate to ethanal and ethanal to ethanol?
sir you are part of my gsce home work and will definitely help
hello sir, do you plan doing a level physics videos for the future? many thanks
no he is not
Just wondering if the Krebs cycle and link reactions are AS level or A level and if you have videos on ldr and lir’s
The whole of respiration is A level. I will be uploading videos on photosynthesis once I'm finished respiration, which will be very soon.
Hi!! Big fans, we love you so much xx Thanks for the videos
Thanks. I appreciate your comment. I'm glad that you find the videos useful.
For A level biology are you videos AQA only or when you put a specific thumbnail does it apply to everyone? Also your A level Chemistry do you cover the OCR spec aswell?
got my a levels end of this year, doing some bio revision now. great to see your still working through the spec, when do you reckon biology will be done?
I am planning to finish all of Biology (and Chemistry) by mid-2025. I'm 50% through now.
@@Freesciencelessons That’s great, I’m doing my a-levels in 2025. Just started y12, using your videos to save me :)
@@Freesciencelessons do you think it'll be possible for you to finish the videos before 2025 a-level exams
Yes I expect to be finished a while before then.
@@Freesciencelessons yay thanks
Hi i just wanted to know when your going to start cellular control?
Really appreciate the work you do in your videos!
Can you let me know what you mean by cellular control? Many thanks.
@Freesciencelessons 1st topic in module 6 of ocr A biology,
There's no rush at all to make the vids I just wanted to know when you plan on making them/ posting them on yt
I see. I'm just uploading the respiration and photosynthesis videos and then I'm going to start the A Level Chemistry Year 13 Organic Chemistry. So I'll start Cellular Control straight after that. I should start uploading in November.
@@Freesciencelessons thank you
Sir, you got me all 9's in my gcses! quick question... do the a level chem and bio vids prioritise only one exam board?
in the thumbnail it lists what specification its from , he covers aqa, ocr and edexcel
they aim to cover AQA OCR and Edexcel, similarly to the gcse videos where videos tagged triple science were not useful to combined students, certain videos are exclusive to exam boards, you can see this as it will have eg: (OCR) at the end of the title.
if in doubt just look at the specification too see what and what isnt relevant to you
Hi and thanks for the comment. The videos tend to cover AQA and OCR and lots of them also cover Edexcel. I put the exam boards in the thumbnail.
Hello just started alevel bio and Chem. You were great at gcse I got all 9s thanks to your videos! When do you think you will finish alevel videos?
Thanks for the comment. I aim to finish all the A level Biology and Chemistry videos by the end of 2024. I'm 50% through now.
Same here
do your a level videos cover a specific specification or just covers any specification?
The thumbnail for each video tells you the exam boards that it applies to (at the bottom).
heyy your videos are really helpful for my IGCSE
