Question

Is this invisible molecular movement in body is necessary for life? If yes or no, why??

Answer 1

The movement of various molecules that cannot be visible with naked eye is invisible movement of molecules. Inside living organisms various chemical reactions are taking place continuously like photosynthesis, digestion, transpiration, respiration etc. all these reactions include movements of numerous molecules inside the body. Movement of oxygen and carbon dioxide gas molecules through blood during respiration, breaking down of water molecules in photosynthesis, movement of solute molecules during transportation etc. are examples of movement of invisible molecules inside living organisms which are highly necessary for life.
Hence, molecular movement is very necessary for life as it provides energy , transport food and water need for respiration and many more.

Answer 2

Invisible movements in human body such as exchange of gases between blood and cells break down of water molecules to release photon for operating cellular operations, Na and K ions movements for neural transmission and many more are vital for the life.

Though these movements are invisible, they are quite significant and vital for the sustenance of life.
