Descibe one cellular activity that uses the energy released by ATP?

Answer 1

The sodium-potassium pump is an active pump working against an electrochemical gradient, and cuts ATP to ADP with every transfer of sodium and potassium across acell membrane.

Most motor proteins are also ATPases, requiring the lysing of ATP with each "movement" of the motor protein in order to function. This is actually the cause ofrigor mortis; although ATP is not needed to cause the muscle's motor proteins to constrict, it is required to allow them to slide past one another into the resting state once more. As death halts respiration, and thus ATP creation, the muscles can become rigid, but cannot relax again (not until other decay processes simply cause these proteins to decay altogether).

The hydrogen-potassium pump that regulates acidity of the stomach contents is also an ATPase.

Answer 2

Muscle contraction is an example of a cellular activity that uses the energy released by ATP. The hydrolysis of ATP provides the energy needed for myosin heads to bind to actin filaments and generate the force required for muscle movement.

Answer 3

Transporting molecules across a plasma membrane and against a concentration gradient by means of active transport utilizes ATP.
