molecular level and because of which sarcomia becomes shortened, so here this is myosin, one of the myosin from this filament which is called molecule which has this tail and its head and these heads are attached to the actin and here what happens is there is the involvement of ATP which is the source of energy adenosine triphosphate so together with this they are energized and then in the next diagram you will see that when this ATP hydrolyze then there is a formation of ADP and inorganic phosphate and this energy which is which is released so that energy it helps in bending this part of it which is the head and since it is attached with the actin and it will push it and in the next diagram after pushing it will move back, this head moves back and for this also ATP needs because ATP for contraction also needs and relaxation also needs and here we are seeing in this diagram that they are parallel they are showing parallel to each other and their distance is the same but in the next diagram this part has moved this way the actin has moved this way but it pushes like this this is a let's say myosin so the actin will do like this like this and these are detached and these are called cross bridges the movement of these cross bridges that all depends upon the ATP ATP will get then it will be bending and it will push and because of this see now it is not parallel but it has moved here and similarly in the next diagram also this head of myosin pushed it and then it is detached now the next cycle which has started like this again ATP molecule is required or this attachment so this is interaction this is what is called interaction between myosin and actin molecules cyclic interaction between myosin and actin in muscle contraction now to start with myosin head is bound to ATP myosin head hydrolyzes ATP to ADP or inorganic phosphate myosin head binds to actin forming a cross bridge your cross bridge now we must be clear about it what the cross bridge is now the the releasing ATP and inorganic phosphate that is responsible for the release of myosin to low energy state now sliding the actin filament or pushing the sliding filament which is the actin filament now binding of a new molecule of ATP releases the myosin head this will be released again and for ugly contraction so the myosin head then returns to high energy level and begin a new cycle once again so this is what is called as the sliding filament theory or molecular level how these z lines they are brought brought closer together and this is the actual contraction which collectively when all muscle fibrils contract then this muscle also contracts and I am again talking about this stress that contraction it is at the expense of energy our relaxation is also at the expense of energy agar agar ATP nahi hai if there is no supply of ATP to muscle contract bhi nahi karega relax bhi nahi karega yeh na samjain ki active contraction head is an active process or relax is automatically ho jaati hai asa nahi hota both this contraction and relaxation they need energy which is in the form of 8 and this is immediate software nahi ji jo hame milti hai aur jis ka hame zikar karenge agle
