Living cells contain DNA, which provides instructions for making proteins such as enzymes. On the other hand, living cell use carbohydrates in the form of sugar and starch to provide energy.
In biology, the cell is the basic unit of living beings. These despite being microscopic have complex functions.
Cells contain multiple organelles such as the mitocondria, the nuclei, the ribosome, among others. In these, one of the most important is the nuclei because this contains DNA (genetic information) that is important for replication and that contains the instructions the cell requires to create proteins. This includes proteins such as enzymes that are essential for metabolism.
To obtain energy cells need carbohydrates mainly composed of carbon and hydrogen atoms. These carbohydrates can be classified into:
