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.
No. Atoms and molecules are what make up all chemicals.
All of chemical reactions in cells breakdown molecules and make molecules.
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.
Enzymes are the molecules responsible for catalyzing biochemical reactions, including the breakdown of food molecules. They act as biological catalysts by lowering the activation energy required for these reactions to occur.
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.
The ozone layer is made up of ozone molecules only. These molecules are reactive in nature.
All of chemical reactions in cells breakdown molecules and make molecules.
To make energy-carrier molecules like NADPH
Chemosynthesis uses inorganic substances such as hydrogen sulfide, methane, and ammonia as energy sources to produce food for organisms. These organisms convert these chemicals into organic molecules through chemical reactions, similar to how photosynthesis uses sunlight to make food.
