Chemical energy is a form of potential energy stored in the bonds of chemical compounds, such as molecules and atoms. This energy is released or absorbed during chemical reactions when these bonds are formed or broken.
Metabolism is the set of life-sustaining chemical reactions in organisms that allow them to grow, reproduce, maintain their structures, and respond to their environments.
Enzyme: An enzyme is a protein that acts as a catalyst to speed up chemical reactions in biological processes without being consumed by the reaction itself
