Question

significance of molecular movement​

Answer 1

$\huge\underline\red{ANSWER:-}$

Molecular movement is essential for life because our cells are in constant need of oxygen and nutrients. Likewise, our bodies must get rid of waste products that would become toxic if they built up. Oxygen is a molecule that constantly moves through our body. We inhale oxygen gas, and it travels from our lungs through the bloodstream to our cells. Carbon dioxide is a molecule produced as a waste product and moves from the cells to the lungs to be exhaled. The foods we eat contain molecules needed by our body, such as carbohydrates, fats and proteins. These molecules are digested and absorbed, and are transported by the bloodstream to various parts of the body to be used for energy and cellular functions. Water is one of the most important molecules that moves through our body, making up a large percentage of our entire body composition.
