NEET BIOLOGY

Detailed explanation-1: -ATP hydrolysis (Chemical energy in adenosine triphosphate → mechanical energy)

Detailed explanation-2: -During active transport, a protein pump uses energy, in the form of ATP, to move molecules from an area of low concentration to an area of high concentration.

Detailed explanation-3: -Mechanical energy depends on an object’s position and motion, and its power comes from the sum of moving (kinetic energy) and stored (potential) energy. In other words, when an object’s potential energy is combined with its kinetic energy, it creates mechanical energy.

Detailed explanation-4: -What is a transfer of chemical energy to mechanical energy? The transfer of chemical to mechanical energy implies the transformation of energy present in the bonds of atoms or molecules to the energy of a body due to its position or motion. Consider the example of a battery-powered toy car.

Detailed explanation-5: -When you eat food, your body can use the chemical energy in the food to make your muscles move so you can breathe, walk, run, jump, lift things, and do all the other things you need to do to live. The chemical energy in the food gets changed into the mechanical energy of moving muscles.
