How does an enzyme break down a molecule
WebApr 1, 2000 · Amylases - Amylases break down starch chains into smaller sugar molecules. Your saliva contains amylase and so does your small intestine. Maltase, lactase, sucrase (described in the previous section) finish breaking the simple sugars down into individual glucose molecules. Lipases - Lipases break down fats. WebDec 30, 2024 · An enzyme that catalyzes the breakdown reaction might bind to the molecule, and in binding it, undergoes a conformational shift that bends or twists the molecule in such a way that the bonds in the substrate molecule are weakened or broken.

WebDigestion is the process of turning the food we eat into energy. For example, there are enzymes in our saliva, pancreas, intestines and stomach. They break down fats, proteins and carbohydrates. Enzymes use these nutrients for growth and cell repair. Enzymes also help with: Breathing. Building muscle. Web* their _____, or molecules on which they act, are organic food molecules which they break down by adding _____ to the molecular bonds, thus cleaving the bonds between the chemical building blocks, or monomers., - …
WebFeb 23, 2024 · Once a protein source reaches your stomach, hydrochloric acid and enzymes called proteases break it down into smaller chains of amino acids. Amino acids are joined together by peptides,... Weblactase, also called lactase-phlorizin hydrolase, enzyme found in the small intestine of mammals that catalyzes the breakdown of lactose (milk sugar) into the simple sugars glucose and galactose. In humans, lactase is particularly abundant during infancy.
