Hi, Can someone please answer this for me?

Explain muscle contraction at a molecular level?

Answer 1

hey it's ur answer

Explanation:

At the molecular level, muscle contraction is defined by myosin molecules pulling actin filaments. ... "Myosin and actin are nanomachines that convert the chemical energy of ATP hydrolysis into mechanical work" he says. Myosin converts this energy by hydrolyzing ATP molecules into movement along an actin filament.

Answer 2

Answer:

At a molecular level, muscle contraction is defined by myosin molecules pulling actin filaments. Myosin converts this energy by hydrolyzing ATP molecules into movement along an actin filament. The hydrolysis involves a number of conformational changes in myosin.
