awww thank you so much!
So happy that the videos have boosted your confidence and hopefully help you to improve your grades. Good luck for your assessments!!
@@MissEstruchBiology thank you so much it means a lot!!!!1
ummmm actually, its Your not You're. Have a good day :)
Thank you so much for your video, they’re very useful!
You're so welcome 😊
The world needs more people like you
so sweet
Hi thank you so much these videos are so clear!!!
You're so welcome 😊😊
Thank you! very clear explanation
You're so welcome 😊 Glad you found it clear to follow
You are a life saver thank you so much
You're welcome 😊 Hope that means the video has helped !
im so cooked how am i resitting and this is what im doing in march for the first time ever
hi miss, why are multiple negative feedback systems needed? Thank you so much for the videos btw
Thanks super super helpful would be nice if their was some questions at the end but the contents fantastic thank you so much!!
So glad you found it helpful :D Ah interesting, I have questions on some of my videos but it made the video quite long and didn't know if it would be TOO long!
@@MissEstruchBiology well it depends because if you make the video too long people might not click on it maybe instead a good idea would be to link some questions in the description with the mark scheme? Just a thought.
@@ethanswift3366 Hello,
In the description already. Lots of topic-based questions at missestruch.com :D hope it helps.
You've made this so interesting thanks a lot
Thanks miss you are the best
aw thanks! You're welcome
I will continue to watch your videos which will help with my GCSE
🌟🌟Hi Miss,I was wondering is this video about the first lesson/section that come up first in Homeostasis?
My teacher not here for the week and she printed out a booklet on Homeostasis.
I don't find the textbook helpful (your video really helped me out with the nerves and muscle topic)
On the booklet it said.16.1 Principles of homeostasis,16.2 Feedback Mechanisms,16.3 Hormones and the regulation of blood glucose concentrations,16.4 Diabetes and its control.
Thank you for your time and have a good day:)
hey, I recommend you watch my complete topic 6 video and skip to the homeostasis section. This covers all of those parts
how does the glucose find its way back from the liver into the blood, please explain as I feel its been missed out.
The process in8:56 and 9:53 is the same right and im guessing adenyl cylcase and adenlyate cyclase is the same thing
i dont want to be a pain, but first it said that the protein adenylate cyclase is activated, but then in another slide it referred to the protein as adenyl cyclase. Is that a mistake, or is it the same thing, and if so then which one do we use. Loved the video btw x
its the same thing . Adenylate is more commonly used though .
6:33 “ more glucose will be absorbed into the blood “ I don’t think so hahahah
🙈 into the cell! Correct in the text.
Thank you! So with insulin, are both protein carriers and protein channels incorporated via vesicles + intracelluar chemicals, whilst exclusively protein channels have their tertiary structures changed to be more.. permeable?
Hello, 👋🏻
It is just channels in the vesicles and it is the carrier's tertiary structure that is altered by insulin binding.
@@MissEstruchBiology Thank you for getting back to me,
-
At minute 6:00 the text says 'this changes the tertiary structure of the channel proteins,' and at minute 7:00 the vesicle diagram is titled 'more protein carriers are incorporated into cell membranes,' were these slight mishaps?
-
Even if there might be (or maybe not this time?) the occasional mistake, by watching your to-the-point videos I have been more or less smashing the exam questions (super unusual of me), thank you for helping me so much ☺️
Instablaster.
@@MissEstruchBiology My teacher originally predicted me a D, yet by using your videos with some other bits & bobs: I got an A on the exams ☺️ Thank You!
@@jamesklieve4620 Well done man. Tryna be like you getting predded a B but ik I can make it a A*
Wallahi I’m finished
same icl
I’m here 10 minutes before p2 begins and this is not going to go well at all lmao
@@desdemona6834 not a single question from this video or respiration and photosynthesis, looks like i'm resitting the year
@@0xE indeed the minute I seen a 5 marker from what is essentially gcse pe pop up I knew it was over
@@enesapaydin925 making an academic come back next year fr fr 😭
Hi miss,Uhm so did you only make 3 videos on Homestasis?And is this the first sub-topic(video) of Homestasis?
I think so yes, and then there is the summa topic 6 video too with it all in
@@MissEstruchBiology Hi Miss,sorry if this seems like a silly question,do you follow the specification when making these videos(is this everything I need to know for this lesson.)Because I rather make notes on your video rather than use a textbook because this is so much easier to understand and get my head around.
@@bellastarmartin4601 Hey, yes they are based on the AQA specification!
@@MissEstruchBiology okay thank you Miss
What topic is this? Is it unit 8?
Its topic 6 for AQA

During stress, adrenaline level in the blood is increased, and adrenaline causes glucose level increase, and insulin level decrease in the blood. Why is that? Isn't the purpose of adrenaline to prepare the body for fight/flight? I understand that increased glucose level means more energy for the body, but isn't insulin needed for the body to actually use the glucose?
Insulin is the hormone produced when the Blood glucose levels are too high. In the production of adrenaline, Insulin receptors are inhibited which reduces the chance of insulin decreasing glucose in the blood, as glucose is needed for respiration as that's the 'flight or fight response; as for using up glucose; that will be done by respiring muscle cells when your body is in that fight or flight situation.
insulin isnt needed for the the body to use the gluose its to get rid of the glucose but in this case we will need the glucose
for respriation whivh is fight of flight.
Omg u explained it so well... thanks like honestly u should pat urself on the back and virtual hug from me ❤
🤣🤣 thank you! So glad you found it easy to follow!
