Why is cellular metabolism considered basic? What two processes are taking place in it?

All creatures on earth originated from the simplest single-celled organisms. There are many millions of cells in the body, and each one performs its own function. The cell is the basis of all living things. It is from cells that tissues, plants, and bones are made. All processes start with a process in one cell. If metabolic disorders occur in any of the cells of the body, then other cells also suffer, a chain reaction occurs. The state of tissue metabolism depends entirely on the state of cellular metabolism.

In a healthy cell, two processes take place: assimilation and dissimilation.

Assimilation is the accumulation of energy.

Dissimilation is the process of releasing energy.
