a really concise, helpful video, with you clearly going through every step in the right amount of detail. just like all your other videos - thanks so much, really appreciate it :)
Please please can you do more of these! They really help me. I am okay with revising all of the Biology content but when it comes to applying it to exam style questions I really struggle! Thank you very much for your help.
For the question that talks about gout and enzymes, how did you know whether or not an enzyme in the question is an competitive inhibitor or a non competitive inhibitor? If it's competitive, can I say that the enzyme has an allosteric site and when that enzyme binds to that one, the shape changes?
Competitive inhibitors are similar in shape to the substrate and therefore bind to the active site. Allosteric site is where a non-competitive inhibitor binds.
Hello, A lot, in fact most, of the theory overlaps but I realise there are some differences. I hope to make videos for different exam boards in 2021. If there is a particular topic you want I haven't covered which is on your specification then let me know.
@@MissEstruchBiology Thank you for replying back. Can please make videos on chapter 15- Coordination from CIE a level biology syllabus ? Hope you gonna make videos for CIE examboard next year it would be really helpful for me and others doing cie a level biology.
i bought some of your question packs and they look really helpful but they have so many questions I don't know when i should do them around revision and general practice. Would you happen to have any advice? Also thanks so much for your help, I actually didn't realise there was a method to answering the questions
maybe start by completing two questions a week. this should take 30-60 mins. As you get closer to exams you could increase this to a few times a week and in exam conditions
Hi Phoebe, I have my new website launching soon with a range of free and pay for products, this is a great idea so I have added it to my 'ideas' list. :)
Hello Miss, thank you so much for this video. if possible in the future could you make more videos on application and add more examples. Thank you once again!
hi miss, I actually just have a couple questions about enzymes. I don't know why I havent thought of then before, but - when we describe enzyme action, we talk about the active not being perfectly complementary to the substrate before it binds? But then in other contexts we do talk about it being complementary/ the substrate or competitive being complementary to it? Then I noticed in MP 2 for that question it said 'igmore complementary'? for the comptetitive inhibitor?
Ah i believe I can help you. With that MP 2, they are not complimentary, u say they are similar shape to the substrate molecule. This is when you talk about competitive inhibitors. But in other situations, such as when pH, temp and non-competitive inhibitors, you mention that the substrate molecule is not complimentary to the enzymes active site
@@MissEstruchBiology thank you for your reply!! I am literally watching all your exam technique videos right now. But what are the 1 and 3 for? I know AO2 is application..?
@@Lavin. AO1 is logical subject knowledge (for example: describe semi- conservative replication), AO3 is analysis and being able to make judgements and conclusions. i think practical skills asw
this video has taught me more in 10 minutes than my biology teachers have over 2 years, you are literally saving my grades, thank you!!!
awww thank you!! So pleased it helped, such a challenging skill
a really concise, helpful video, with you clearly going through every step in the right amount of detail. just like all your other videos - thanks so much, really appreciate it :)
thank you 😊
Glad it helped

so glad it helped ! Check out my exam technique playlist and I have more there 😁
Thank you so much for this! I was really stressing out for my mock exams but now I have a clearer idea of how to asnwer application questions!
You're very welcome ☺️ So pleased it's helped boost your confidence before mocks!
Wow thank you really made me consider my approach to these questions :)
I hope it helps you in your next test!
Jazak Allah
Really good video as normal so helpful
thank you Mark 😊
A well made video, thank you for making these
Thank you ☺ Glad you think so.
Amazing video👍🏼
Thank you!!! 😊

Thank you so much ! . Can you please make videos for cie a level biology? It would be really helpful .

I really appreciate your time you are taking to guide me but I am requesting you to write what you are saying in form of a lyrics
wow not sure I'd be capable of that! Lyrics is next level

actually very helpful
thank you. Pleased it helped
Thank you!!
you're welcome 😊
could you make some mindmaps/ documents of key words and phrases from mark schemes for each AS topic please
Hi Phoebe,
I have my new website launching soon with a range of free and pay for products, this is a great idea so I have added it to my 'ideas' list.
:)
is the application question booklet still available on your website please ?
yes! in the assessment skills bundle

Hello,
Yes, I hope to do some more exam questions in 2021 😊
thank you miss
You're welcome! Hope it helps with your exams 😊
@@MissEstruchBiology yes miss it has my exam is tomorrow :)

how many AO's are there??
3, LO1 , 2 and 3
