C) comes from ionic energy motion.
D) is elevated by a catalyst.
E) can be lowered by enzymes.

Chemical Reaction

A process that leads to the transformation of one set of chemical substances to another through the breaking and forming of chemical bonds.

Activation Energy

The minimum amount of energy that is required to initiate a chemical reaction, determining the reaction rate.

Enzymes

Biological molecules that act as catalysts, speeding up chemical reactions in living organisms without being consumed in the process.
