A Level Biology Revision "End-Product Inhibition"

You can find all my A Level Biology videos fully indexed at www.freesciencelessons.co.uk/...
In this video, we look at end-product inhibition. First we explore what is meant by a metabolic pathway, looking at two examples. We then see how end-product inhibition is used to regulate the rate of metabolic pathways. Finally, we look at how end-product inhibition is an example of negative feedback and why end-product inhibitors are non-competitive inhibitors.
This video is aimed at the UK A Level Biology specifications. Students studying International A Level Biology will need to check their specification.

Thank you for this set of videos! My school just started teaching this chapter, and I'm so relieved that the timing of your uploads matches with what I'm learning!

[@dian4343]

I hope all the teachers are just like you and so I don't have to study everything on my own

[@rawanyousef8494]

Youre videos are amazing!

[@ea6334]

These videos are great! Please may I request videos for Module 4 (disease and immunity, biodiversity) and module 6 (genetics) for the OCR A a-level spec?

[@Freesciencelessons]

Hi and thanks for the comment. I'll be covering all the modules for the OCR and AQA Biology A levels so you should see them appearing in the next few months.

[@abdulraheemhabeeb6921]

Please cover A-Level Physics content as well

[@SP-gc1pr]

Hello sir, could you do a video on hypertonic, isotonic and hypotonic solutions please? It would be greatly appreciated

[@Freesciencelessons]

I'll be doing that video very soon.

[@SixofCrows44]

Hello, sir
Will you be covering the rest of the biology spec, or not?
I have seen on your website that your videos go up to transport in plants, but I was wondering if we get videos on homestasis, variation, evolution and all that stuff?
Thank you for helping all my science GCSE be at a grade 9, sir.

[@Freesciencelessons]

Yes I'm about to upload five more A level biology videos. I'll be completing the whole course over the next year.

OH MY GOD IM FIRST TO A FREESCIENCELESSONS VIDEO

[@sanakamran1400]

Yayyyyy

[@jacobdawson6238]

my textbook says end product inhibition is competitive 💀

[@Freesciencelessons]

In order for that to be the case, then the end product of a complex metabolic pathway would have to have a similar structure to the substrate of the first reaction and bind to the active site. That does not happen. Instead, the end product binds to the allosteric site and is non-competitive.
