enzymes
Reactants
They are called enzymes. They aren't necessarily considered molecules, but I suppose they are, perhaps very large ones. These enzymes act as a catalyst to speed the decompositions along. Stomach acid helps by oxidising the food as well as creating the environment for the proteins to function.
enzymes
All of chemical reactions in cells breakdown molecules and make molecules.
Those types of molecules are called enzymes.
No. Atoms and molecules are what make up all chemicals.
Catalysts are chemicals that can speed up a reaction but don't actually get used up themselves. Catalysts that slow reactions down are called negative catalysts or inhibitors. Manganese dioxide is a catalyst that speeds up the breakdown of hydrogen peroxide into water and oxygen. When a catalyst acts in a living organism it is called an enzyme. Human saliva has the enzyme amylasewhich breaks down carbohydrates into glucose.
