- create a flow chart or diagram to illustrate the digestion and absorption of carbohydrates. The starting carbohydrate molecules are starch, sucrose, lactose, glycogen, and cellulose. What will happen to these carbohydrates once we ingest them? Include the following from your flow chart or diagram: 1) the location or site where the digestion or absorption occurs 2) the enzymes 3) the products generated at each site or locationMany people who are lactose intolerant can eat yogurt, which is prepared from milk curdled by bacteria, without any digestive problems. Give a reason why this is possible. (Hint: Read the label on each of several yogurt containers. Do the ingredients make a difference?)Question:- diagram, use D with arrows to show how disaccharides like lactose and sucrose get from food to the small intestine. - Use E to indicate the location of the enzymes, lactase and sucrase. - Use M to indicate where monosaccharides like glucose are produced from disaccharides.
- To prevent tooth decay, nutritionists recommend replacing sucrose in kindergartens with non-carbohydrate sweeteners. Q: write the reaction of dissociation of the final product of this metabolic pathway, causing a shift in pH in the oral cavityEnzyme 1 has peak activity at pH 2.4 and Enzyme 2 has a peak activity at pH 8.4. Which of the following choices correctly identifies the two enzymes? A) 1- pepsin; 2- lingual lipase B) 1 - pepsin; 2 - carboxypeptidase C) 1 - trypsin; 2 - aminopeptidase D) 1- trypsin; 2 - amylase E) 1- trypsin; 2- pepsinEstimate the optimum pH for the digestive enzyme trypsin, which hydrolyzes proteins in the small intestines, from the following graph.
- Which products of fat hydrolysis would cause a change in pH of the whole milk sample? Why does a person with a low production of stomach HCl have difficulty with protein digestion? Write the equation for the action of Pancreatin (lipase) on a molecule of Tristearin.The first step in amino acid catabolism usually involve transamination.since ammonia is a serious neurotoxin, the body maintains the nitrogen and ammonia balance carefully. Discuss the pathway, organelle and organs involved in maintaining this balance. Provide a schematic presentation of the pathway to supplement your discussion.From the oligopeptide below, write completely the amino acids and/or peptide fragments that resulted from the reaction of pepsin. The amino acids and residues should be represented by the three-letter abbreviation.
- The first step in amino acid catabolism usually involves transamination. Since ammonia is a serious neurotoxin, the body maintains the nitrogen and ammonia balance carefully. Discuss the pathway, organelle and organs involved in maintaining this balance. provide a schematic presentation of the pathway to supplement your discussionGram for gram, fatty acids provide more energy than carbohydrates. For this reason, triacylglycerols were evolutionarily selected as the main energy storage molecule over glycogen. 1) In a sentence or two, explain why fatty acids are capable of providing more energy than carbohydrates. BE SPECIFIC. 2) The answer to PART 1 actually creates complications in how lipids are digested. Why is this? 3) Now consider the fatty acid stearate. Stearate contains a total of 18 carbon (C) atoms and, when it is oxidized, a TOTAL of nine acetyl CoA molecules are produced. As you know, every molecule of glucose contains a total of six C atoms, so three glucose molecules have the equivalent number of carbons as one stearte. A) How many acetyl CoA molecules are produced when three glucose molecules are oxidized? B) Considering ALL of the above information, please explain why three glucose molecules DO NOT provide the same amount of energy as one stearate molecule.
