Enzyme Reactions Name_______________________ Period _____ Date____________
Sucrose is a sweetener found in many candies. It is a carbohydrate disaccharide made up of glucose and another sugar called fructose. When we eat sucrose, it must be digested or broken down into smaller substances, which our cells can absorb. An enzyme (protein) called sucrase speeds up this chemical reaction by breaking the chemical bond in sucrose, the substrate. High heat and strong acids or bases destroy the enzyme and would stop the chemical reaction. The only way to make the reaction go faster is to add more enzymes. Scientists support the “lock and key” model below for how an enzyme speeds up chemical reactions. The letters “ ase ” at the end of words help us identify enzymes.
pH and Enzyme activity
Experiments were designed to study the effect of pH on the rate of enzyme action for 2 different enzymes found in animals, Enzyme A and Enzyme B. Enzyme A is found in the stomach and digests meats. Enzyme B is found in the intestine and digests facts. Use the graph to answer the following questions
