Small amounts of pepsin pass from the stomach into the bloodstream, where it breaks down some of the larger, or still partially undigested, fragments of protein that may have been absorbed by the small intestine. What would most likely happen to pepsin as it enters the small intestine?When pepsin enters the small intestine, it becomes inactive. Pepsin is a strong enzyme that becomes active once in the presence of hydrochloric acid… Which enzyme would most likely function in the stomach? In the stomach, pepsin is the main digestive enzyme attacking proteins. Several other pancreatic enzymes go to work when protein molecules reach the small intestine. Lipase is produced in the pancreas and small intestine. How does pepsin break down a substrate? The specific reaction catalyzed by pepsin is the acid hydrolysis of the peptide bond. This reaction will break down proteins into smaller units to enable the digestive process. Pepsin demonstrates an unusual property for an enzyme; it does not actually form chemical bonds with its substrate. Why would you not want to completely suppress HCl secretion in the stomach?Why would you not want to completely suppress HCl secretion in the stomach? – HCl begins denaturing proteins in food, and provides the proper chemical environment for activating pepsinogen into pepsin, which breaks apart certain peptide bonds in proteins. Which of the following best predicts how structure and function of pepsin will change as it enters the small intestine?Which of the following best predicts how the structure and function of pepsin will change as it enters the small intestine? Pepsin will change in shape because of the basic environment of the small intestine; therefore, its enzymatic activity will decrease. What happens when pepsin enters the small intestine nutrition quizlet? What happens when pepsin enters the small intestine? It cleaves proteins into smaller peptides and some free amino acids. Which is the most likely function of the enzyme pepsin? Pepsin is a stomach enzyme that serves to digest proteins found in ingested food. Gastric chief cells secrete pepsin as an inactive zymogen called pepsinogen. Parietal cells within the stomach lining secrete hydrochloric acid that lowers the pH of the stomach. Where does enzymatic protein digestion begin?Protein digestion begins when you first start chewing. There are two enzymes in your saliva called amylase and lipase. They mostly break down carbohydrates and fats. Once a protein source reaches your stomach, hydrochloric acid and enzymes called proteases break it down into smaller chains of amino acids. How is pepsin produced in the small intestine?Pepsin is produced by cells lining the stomach. It catalyzes reactions needed to digest certain proteins. After leaving the stomach, food enters the small intestine. The pH of the small intestine is around 7. What would most likely happen to pepsin enzymes that traveled with the food from the stomach to the small intestines? What happens to enzymes in the small intestine? What would most likely happen to pepsin enzymes that traveled with the food from the stomach to the small intestines? The pepsin would become inactive. The pepsin would continue to digest proteins in the small intestine. The pepsin would turn into the enzyme arginase. The pepsin would become inactive. What happens to food when it enters the stomach? Stomach: The stomach is an important organ of the digestive system, which helps to mechanically and chemically break up food that enters through the esophagus. Gastric Juice: Gastric juice is a combination of acid and enzymes that facilitates chemical digestion of food. How are enzymes able to speed up chemical reactions?There are no molecules in this reaction. Enzymes are catalysts. This means that they are able to speed up chemical reactions. Which of the following statements is also true of enzyme catalysts? They are not used up by reactions. They must be continuously replaced after each catalyzed reaction. Which of the following statements best helps explain how the enzyme speeds up the reaction quizlet?Which of the following statements best helps explain how the enzyme speeds up the reaction? The enzyme's active site binds to and stabilizes the transition state, which decreases the activation energy of the reaction.
Which of the following statements best helps explain the reaction specificity of hexokinase quizlet?Which of the following statements best helps explain the reaction specificity of hexokinase? Glucose has the right shape and charge to cause hexokinase to undergo a structural change needed for catalysis, whereas water does not.
Which of the following is true about pepsin?What enzyme is responsible for carbohydrate digestion in the small intestine? Which of the following is true about pepsin? Pepsin breaks down protein into glucose.
Which of the following is directly responsible for the shape of an enzyme protein?Which of the following is directly responsible for the shape of an enzyme/protein? The amino acid sequence of the protein and the properties of the amino acids that make up the protein.
