Which protein hydrolyzes atp during contraction?

Myosin.

Explanation:

Myosin is an ATPase, that is, the subset of enzymes that are capable of producing the hydrolysis of adenosine triphosphate (ATP) into adenosine diphosphate (ADP) and a free phosphorous ion (phosphate ion).

Answer

Myosin

Explanation:

Myosin is an example of motor proteins which depends on ATP hydrolysis to function during muscle contraction. They are primary located in the muscles cells. Other motor proteins are Kynesin and dynein.

Basically, myosin bind with actin to cause motility,hydrolyses of  ATP and   force transduction for muscle contraction.

Structurally it is made up of  three domains the head, through which it binds with the actin, the linker neck through which it binds with the  light chains, and  tails which interact with the cargo molecules.

homeostasis is the tendency towards a relatively stable equilibrium between interdependent elements, especially as maintained by physiological processes. and this is how it applies to the integumentary system. back to top. skin functions in homeostasis include protection, regulation of body temperature, sensory reception, water balance, synthesis of vitamins and hormones, and absorption of materials. when body temperature falls, the sweat glands constrict and sweat production decreases.
