GCSE Biology - Enzymes - How Temperature and pH Affect Rate of Reaction 

Whose watching this for exams tomorrow 😅

Your channel’s existence helps me sleep at night.

You teach better in 3 mins than my teacher in 1hr

your videos and especially your website has made revision fun for me and i am so grateful, keep up with the great work!!

Fun fact: enzymes in the small intestine are opposite to the stomach enzymes and work best at alkaline conditions :D this is why it’s so useful that bile neutralises the hydrochloric acid in the stomach, meaning the enzymes can then work at their best and fastest when the food goes into the small intestine. (I do hope that’s right lol)

I started using your website, really happy with what I’m learning from it!

i started using your website it makes it so easy to revise

Your website and videos are FANTASTIC! Please provide more explanations on various topics. Thank you!!😁😁

Hi Cognito👋👋 Thank you so much for your interesting videos as they make difficult topics much easier to understand. So once again thank you so much! Also a kind request, would please try to make a video for Upper bound and lower bound? Because I am sitting for my OLs this May so this would help me learn this particular "BOUNDS" chapter more quicker...📓📚😊😊 Would you please upload?? 😭😭😭 As I enjoy and learn with interest when I see your videos Cognito.......... Even my school teachers weren't so clear and didn't make my lessons so interesting

Thank You for helping me in my exams.

Thanks - biology exam soon!
