What is a protein that catalyzes chemical reaction for organisms

Each atom becomes different from the next by having different number combinations of these subatomic particles. The different numbers of protons electrons and neutrons determine different elements or in other words a pure substance made from a solitary kind of atom
Every element has different qualities or physical characteristics for example oxygen and gold The former is a gas that is one of many elements making up organic matter Where as the latter is solid and inert a non-reactionary element
