They are single-celled organisms, they cannot be multi-celled.
Prokaryotes do not have a nucleus to contain their DNA, and they do not have organelles.

Enzymes
Because enzymes are proteins, they do some of the work in the body, for example, they make the proteins that make up your muscles.
Enzymes are known as catalysts, because they speed up the process of certain reactions, and give the same results. They also reduce activation energy needed for the process.
All catalysts are not enzymes, but all enzymes are catalysts.
-
When an enzyme is denatured, it loses its shape and cannot do its job anymore. It usually is denatured by temperature change.
When is brought back to its usual temperature, it can reform.
The lock and key concept is used for enzymes because other substrates cannot be used in an enzyme, it only fits like a key with the substrate it is made for.
They can break bonds, and then build them again.
