did you write it or can you give a credible reference for it (not the orange book) because it doesnt make sense why would energy be needed to bring the myosin head to its original position ? it will just SPRING back once it is released from the actin.
salters nuffield advanced biology for edexcel A2 student book. it doesnt spring back, energy is required for any movement of the head.
if you read the step by step that is exactly how it happens, also when the other person said it breaks down the bridge, that is what i am saying, what do you think happens in the sliding filament theory?? i thinks its exactly the same as me but in different words tbh.
you still havent answered me LOGICALLY.
why would energy be needed once the power stroke is over ??! do v have extra energy we wanna get rid of ? what ?!

so thats the case. apparently that isnt the case in EDEXCEL book or SNAB rev guide ! well i guess ill stick to what the main ones say . i dont think salters nuffield is for us, not that it changes the reality of what actually happens, but theres too much apparent confusion.....

that entire process was outlined in the bullet points i provided, the ADP and Pi are released for the power stroke and the new ATP is hydrolysed to move the head back once detached, that ADP and Pi is then released for the next power stroke. If you dont agree with that you dont have to thats just what it says in the text book.

well, I just wanna make sure that the idea is clear to me as well to you ! but clearly it isnt.

clearly not, im just relaying information that is in every animation and text i have read, apologies for not thinking in the same pattern as you but no need to be rude just trying to be helpful

lol. when was i rude ? haha. but the main point is after all the discussion the concept is still vague. what you are sayin MAY BE correct. but it lacks logical explanation.

sorry you obviously didnt mean to be rude it just came across that way, I've just learnt the exact process from the text book, doubt they will ask for an explanation as to why it happens
thanks XD i was starting to doubt myself for a minute there
Lol the student room confuses me a lot as well because everyone has different notes
- My notes say that ATP binds to the myosin head causing it to detach from the actin filament. - This activates ATPase in the myosin head, which hydrolyses ATP; providing energy to return the myosin head to the original position.
And from what i read, i think you basically said the same but in a shorter version lol

yeah thats what i've got this entire exam has way too information for 6 questions and a pre release i swear

I know! Really not looking forward to the pre release questions. My notes for unit 5 are almost double the amount i had for unit 4 :/ i wish it was easy to predict certain topics so we wont have to learn it all lol
