Look into the sliding filament model. If you look up the spec for your exam board (eg. ocr, aqa,edexcel etc) you'll find exactly what you need to know. I also recommend getting a textbook for A-level biology as it will answer most of your questions and you won't need to wait for a response from tsr.

I put these:
Actin: spherical protein that forms filaments + involved in muscle contraction + other important cellular processes

Myosin: protein that converts chemical energy in form of ATP to mechanical energy

I tried using the edexcel textbook but it doesnt explain the roles of these proteins

they attach to eachother + stretch in order to make muscles move. I don't know how in-depth of an answer you are looking for
