Hi there! If you're an A-level Biologist, then this channel is for you :)
Here you'll find short videos that explain A-level Biology topics. It's based on the OCR A specification, but it should help all of you regardless of the exam board you're using.
Good luck with revision and do get in touch to let me know what you think of the content!
If you liked my videos and would like to support me, then I'd really appreciate you buying me a cup of tea or a piece of cake! :D www.buymeacoffee.com/biorachproject

GCSE Biology - B9 Respiration OVERVIEW
This video is on respiration, focusing on the two types of respiration, how our body responds to exercise (to maximise rate of aerobic respiration!) and also a bit about the liver. Please note that a lot of higher level exam questions like to test students on linking respiration to various topics, such as photosynthesis (greenhouses) and diseases (e.g. coronary heart disease, damaged valves, mineral deficiencies in plants) - it is essential that you understand respiration well! Usually the mark schemes for thes types of questions would include points such as:
1. More/Less glucose and/or oxygen delivered or supplied
2. More/Less aerobic respiration can occur
3. More/Less energy is released; Or more/less glucose is made
4. More/Less energy for growth; Or more/less proteins can be made (leading to stunted growth or lack of enzymes for key reactions)

Amazing thank youuuuuu
Thank you for your videos!!!! Prepping for ocr paper 3 and your videos are super helpful :'))
isn't it called Adenylyl cyclase, not Adenyl cyclase?
would the casparian strip also count?
fr saving me, bless u <333
im cooked
AHAHAH😭😭😭same bro
Oh my I love you
I love you
exam tomorrow using your vids to do some last minute cramming!!! you’ve been so helpful thank you so much!
Thank you so much :D
Thank you so much, this has really helped to clear up genetic variation and meiosis for me :)
I havent touched a single page of module 4 and 6 but your video saved me
😭😭
thank you so much. i do aqa and have paper 2 soon and thisvid explains it perfectly
Is there a vid on gene therapy i think you missed it out on the chapter 21.
thank uuuu u helped me so much with my a level biology ❤️❤️❤️🐊🐸👁️👈
You havent done 21.5
Where are the videos for 24.7 -24.9
have you done videos for 23.4 and 23.5
You are saving lives out here!
you are a life saver
For temp could u say it causes both Intrinsic proteins and extrinsic proteins to denature and does this increase or decrease permeability?
Would u say if channel proteins denature that permeability would decrease because polar molecules can no longer be transported in the membrane?
I'd be cautious when linking transport proteins with permeability. When they denature due to heat, there is no telling how the structure changes to make them more "open" or "closed". The membrane permeability will definitely change but it's risky to say it increases or decreases.
can you please make a video on 23.4
this video is a life saver helped me sooo much
I'm studying about scurose translocation and many people have made about it. But you channel is the clearest to understand. Thank you from old guy , Japan!
you've made it so straightforward
Absolute stellar explanation you have a talent for teaching
