Enzymes work by lowering the activation energy (the amount of energy needed to start a reaction). . IMPORTANCE. OF ENZYMES. Enzymes are biological catalysts that:. .

Each enzyme has only one specific reaction it can perform. . 2. How many different reactions can a single enzyme perform?. Yes, the same enzyme molecule can be used over and over. Most abundant molecule in cells making up 50% or more of their dry weight. Every protein has a unique structure, or shape. Allows it to perform a specific function. Enzymes are proteins that function as catalysts for many reactions in foods. Bio-Chemistry (AKA Organic Chemistry). Inorganic Compounds. : from minerals or non-living source.. Organic Compounds. : contain . Carbon. & come from a living thing.. Carbon can combine with other elements to form millions of compounds.. Enzymes. Back when we discussed proteins, we learned that one critical function of protein was to speed up chemical reactions..
