Question

nervous system mechanism ?

Answer 1

The nervous system is made up of all the nervecells in your body. It is through the nervous system that we communicate with the outside world and, at the same time, many mechanismsinside our body are controlled. ... The brain alone has about 100 billion neurons in it. Each neuron has a cell body and various extensions.

Answer 2

The sodium-potassium pump carries out a form of active transport—that is, its pumping of ions against their gradients requires the addition of energy from an outside source.

That source is adenosine triphosphate (ATP), the principal energy-carrying molecule of the cell.

ATP is formed by an inorganic phosphate molecule held in high-energy linkage with a molecule of adenosine diphosphate (ADP).

When an enzyme in the pump, called sodium-potassium-ATPase, splits the phosphate from the ADP, the energy released powers the transport action of the pump
