In this video, I explain ALL of the content required for the "Muscle Contraction" section for AQA A Level Biology. This includes: structure of myofibrils, sliding filament theory, and fast +slow twitch muscle fibres. Time stamps are in the comments section and the content in this video crosses over with other exam boards too!
I
also go through a few exam questions and explain the mark schemes.
Please leave a comment if you have any questions, I'll be more than happy to answer them!!! :)
