Phosphatase Ribonuclease Salivary Amylase Sucrase Trypsin e process of chemically digesting a complex carbohydrate such as a starch from start Be sure to include any enzymes involved in the process, where in the body they are 34. Describe th to finish. produced, what substrate molecules the enzymes act on, and what products are produced fronm the reactions. List the three main dietary disaccharides, and for each, specify the enzyme that facilitates the reaction that digests them into monomers. produced when they are chemically digested Also for each, list the monosaccharides that are 36. What is a zymogen, or proenzyme? What is the purpose of proenzymes fi.e. why don't cells produce proteases in their active form)? 37. For each of the following proteases, check the appropriate box to indicate if the protease is its zymogen form, or active form: Protease Pepsin Zymogen (Proenzyme) Active FormExplanation / Answer
34)
The digestion of carbohydrates starts at mouth. Salivary glands in mouth moisten the food by secreting saliva. Food is next chewd with the help of enzyme Amylase which is secreted by salivary gland. Amylase helps to breakdown the complex polysaccharides structure of carbohydrate.
The food is next get mixed with salivary amylase and other salivary juices and passed to the stomach through eosophagus. In stomach the food is known as chyme and stomach acids help to destroy bacteria from the food and amylase production is get stopped.
From stomach chyme enters into duodenum. In a response to that pancreas secrete enzyme pancreatic amylase which breaksdown polysaccharide further into disaccharide. Next, small intestine produces enzymes suhc as lactase, sucrase and maltase which are further breks disaccharides into monosaccharides compund. Monosaccharides next get absorped by small intestine.
Next, carbohydrates which are have not been absorped by small intestine get passed to colon and breaksdown in part by intestinal bacteria. Fiber particles which are not digested are excreted outside of the body.
35) Three dietary diasaccharides are sucrose, lactose, and maltose.
Sucrose is digested by sucrase and produce glucose and fructose
Moltose is digested by maltase to glucose
Lactose is digested by lactase to glucose and galactose.
36) Zymogen or proenzyme are group of protein which lack the catalytic activity and function as inactive precursor of enzyme. Zymogen are neceassary so that the digestive enzyme will not digest their prducing cells.
