What is the advantage to cell to be able to move molecules against the concentration gradients

In order to move molecules against the concentration gradients, the cell must have the advantage of Creates energy

Explanation:

When a solute is concentrated to a particular area it is called as concentration gradient. The law of thermodynamics well explains that a molecule moves from area of higher concentration to lower concentration.  

If a molecule moves against the concentration gradient it is called as Active transport. For this process to happen the cell needs to energy efficient.

Energy is been released and it is stored in the form of bonds between the atoms during active transport. To maintain the proper balance in the molecules and the balancing of ions active transport is essential.

answer is a
