A2 Biology - Aerobic respiration stage 4: Oxidative phosphorylation (OCR A Chapter 18.4)

[@aniqahbuckingham7947]

My teacher gave up teaching us so you are now my bio teacher... You're great :)

[@isaacfisher2482]

Spent 2 days making notes on respiration but you just summed everything up in 15 mins, wow 😂😂

[@alexandragracelyon2878]

This is amazing! Thank you I never understood this from my textbook but visually how you laid it out it, it makes it simple:) Could you possibly do a video on neuronal communication topic? Specifically the muscles topic and the brain?

[@BioRach]

Hi Alexandra, thank you for watching and I'm glad you find it helpful! Personally I find the textbook complicated as well, so I do hope these diagrams would help :D I am planning to do a new series on neurones, possibly starting from resting potential and work my way through. Just keep checking this channel :D

[@bscreations2154]

SAME HERE. Thank you so much @BioRach this video was amazing and made it a piece of cake!

[@emmabaker2070]

Thank you so much for taking the time to make these super helpful videos! It's such a great way to review content!!! :)

[@BioRach]

I'm really glad to hear that the videos are helpful :D It's pretty much how I teach the topic in the first place, but it's still a great way to revise. Thanks for watching!

[@abic05]

i missed respiration when it was taught in class and my exam is tomorrow, this is a total lifesaver!! thank you for helping me cram!! :D

[@Sara-sc6nm]

Thank you so much for making this. It was really detailed and you explained it so much better than any videos ive watched!

[@vedantbhardwaj7582]

This is actually brilliant! Miss you are an extremely good Biology teacher!!!! Thank you sooo much!!!!!!!!

[@anaums413]

You are such a legend

[@atiarimi7322]

This is a great video, the diagram and your explanations just made it so easy to follow, thank you !

[@nateayi]

You're saving my paper 3!!!

[@viclate428]

Thank you so much. So clear! The textbook was unhelpful 👏🏿❤️

[@TJ-Lalala]

2:23 though apparently it isnt active transport as the energy to “actively transport” the protons come from electrons being passed on rather than ATP?

[@kelisa4894]

It’s still active transport bc energy is being used :)

[@brijeshpatel6772]

The best biology channel!

[@BioRach]

Haha thank you! :D

[@bunnyb3977]

All your videos are so helpful. Thanks a lot!!

[@KeiraSmith-d2t]

Thank you so much!!!! Everything finally makes sense :)

[@meggiedoeshair]

I dont do OCR, but this video was amazing! I tried multiple videos, but this is the only one that helped! :)

[@BioRach]

Glad it helped! Thanks for watching!

[@daniella3683]

Thank you so much for making me understand this!! Ur amazing pls continue to make videos like this

[@mussesisay2136]

You explain it well

[@meemoozee]

Awesome explanation 👍! Will buy you a coffee one day :)

[@BioRach]

Glad you found it helpful! Thanks for watching, and the coffee :D

Love you! You’re awesome

thamkyou very much maam mayGod bless u

Hi just wondering what exactly substrate phosphorylation. Is it a way of making ATP without using oxygen as the final electron acceptor.

[@BioRach]

Yes exactly that. The ADP gets the phosphate group from a phosphorylated reactant within the chain of reactions (hence we call it a substrate) to become ATP. This whole process occurs without using the ETC. It becomes an ATP simply by grabbing the phosphate group from another chemical. Hope this helps :)

[@ini6325]

BioRach Okay I see thank you very much. Does it occur in both glycolysis and kerbs but not in the link reaction?

[@BioRach]

Yes you are correct - in glycolysis it is between triose bisphosphate and triose phosphate (when TB loses a P group to ADP, and becomes TP itself). In Kerbs cycle, it is "the first step" of a 4C compound converts into oxaloacetate. Link reaction is an oxidative decarboxylation reaction - where NAD is reduced and carbon dioxide is made, converting pyruvate into an acetyl group. For details, you can refer to the two videos I've made for these stages in aerobic respiration :)

[@faizanrasheed3087]

Does your videos cover the A2 syllabus which comes in exam like it will I miss on anything if I revise from your videos?

[@kazishahjalal6852]

This a masterpiece

[@michaelrowland-us3he]

Where is stage 1 to 3?

[@BioRach]

In other videos in this chapter playlist. You can find them on my channel.
