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.

answer: - few nutrients

high pressure

low temperatures

explanation: 1. few nutrients:   open-ocean zone is located way far from the land, which is the main source of the essential nutrients.2. high pressure: pressure increases by 1 atmosphere for every 10 meters increase in depth.3. ample sunlight: a large fraction of the sunlight is reflected back to the atmosphere from the sea surface. 4. varying salinity: below the thermocline, the water is isolated from the atmosphere so the salinity remains stable over the year.5. low temperatures:   the temperature of open-ocean zone ranges from a low of -2°c to an average of 17°c

c. is the correct answer
