enzymes
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.

Coenzymes. Coenzymes are organic molecules that assist enzymes in catalyzing reactions by binding to them and helping in the transfer of chemical groups or electrons. Examples include NAD+, coenzyme Q, and vitamin B12.
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.
This energy is derived from the chemical bond energy in food molecules, which thereby serve as fuel for cells. The first step is the enzymatic breakdown of food molecules in digestion, and the second step that converts glucose molecules is called glycolysis.
Each chemical can serve various functions depending on its type and context. Generally, chemicals can act as reactants in chemical reactions, participate in the formation of new substances, and serve as catalysts to speed up reactions without being consumed. Additionally, they can function as solvents, providing a medium for chemical interactions, or as signaling molecules in biological systems, facilitating communication between cells.
Molecules or compounds that function to allow a reaction to take place but do NOT take place in the reaction itself are called catalysts. Biological catalysts made of proteins are called enzymes.
Yes; enzymes can be simple or complex molecules that serve to catalyze biological reactions.
In cells, synthesis and decomposition reactions are coupled through metabolic pathways. Synthesis reactions build complex molecules by combining simpler ones, while decomposition reactions break down complex molecules into simpler components. These reactions are interconnected in metabolic pathways, where the products of one reaction serve as substrates for another, allowing cells to efficiently produce and break down molecules as needed.
Enzymes are molecules that act as catalysts to facilitate the breakdown of food molecules and other chemical reactions in the body. They lower the activation energy required for the reaction to occur, allowing it to proceed at a faster rate. Enzymes are specific in their action, targeting particular substrates to catalyze specific reactions.
