The energy released is used for assembly of actin filament with myosin head. when myosin is attached to ATP its heads cannot bind to actin and therefore muscle will remain in relaxed form. However during muscle contraction an enzyme referred to as ATPase hydrolyses ATP to ADP and organic phosphate in the process releasing energy. The energy released changes the position of head of myosin which facilatate its binding with actin. Myosin moves towards m-line dragging actin along with it reducing the length of sarcomere leading to muscle contraction.
It is an abiotic factor.
An abiotic factor is something that will never be alive.
Ex. Dirt, clouds, air.
I hope this helped you!
Microtubules are composed of two different types of tubulin. Namely, these simpler units are called alpha-tubulin and beta-tubulin. These subunits are essentially tightly bound together to form heterodimers. In the microtubule structure, they are arranged in an organized manner in such a way that they in parallel direction with protofilaments.
