Bacteria metabolism!
Anabolism (building up)
The chemicals taken up by the bacteria are used to build cell parts. They take the carbon and nitrogen out of the soil water and air and use it for making those cell parts.
Catabolism (breaking down)
When chemicals break down they release energy and that is where the microorganisms get the energy to break down the chemicals even more and use them for themselves.
The role of those in bioremediation
-The contaminants in the soil water or air are the building blocks for the cell parts.
