How does your body use the protein once it has been ingested? Consider the following statements and select the correct ones regarding protein use. Select all that apply. ► View Available Hint(s) Amino acids are used to create new proteins. If you ingest more protein than your body needs, the protein is stored in muscle. The liver uses amino acids to create glucose. If calorie intake is inadequate, amino acids can be used for production of energy In this activity,...

Which statement about protease secretion and activity during protein digestion is correct? A. Pepsin is a protease that degrades proteins in the small intestine. B. Secretin is a protease that neutralizes stomach acid during digestion. C. Cholecystokinin (CCK) triggers active protease secretion from the pancreas. D. Trypsinogen is a protease that converts zymogens into active proteases. E. Trypsinogen is the substrate of enteropeptidase in the small intestine.

Which of the following is a way that digestion and absorption of carbohydrates differs from that of proteins? a) Only carbohydrate absorption involves cotransport driven by Na+ gradients. b) Only protein absorption involves cotransport driven by H+ gradients. c) Only carbohydrate absorption involves digestion via brush border enzymes. d) Only protein absorption involves facilitated diffusion transporters that allow the digested monomers to enter the interstitial fluid across the basolateral membranes of gut epithelial cells. e) Only during protein absorption are...

Each day, the pancreas produces up to 1.5 L of pancreatic juices that enter the duodenum via the pancreatic duct. The pancreatic juices consist of water, salts, bicarbonate ions, and digestive enzymes. Bicarbonate ion raises the pH of the acidic chyme from the stomach, stopping the active ity of pepsin and allowing the pancreatic and intestinal enzymes to function. The various pancre. atic enzymes and their substrates are listed in Table 10.2. Table 10.2 Various enzymes produced by the pancreas...

Can someone answer these questions please!? Need help!!!! 1. Compare the optimum pH results obtained for amylase and pepsin with those predicted in the Pre-Laboratory Assignment. Discuss any possible discrepancies between the predicted and experimental results. 2. What was the purpose of including control samples containing only substrate and buffer (test tubes 1−4 for each enzyme) in this study? Did any of these mixtures show any reaction? 3.

Which of the following statements is FALSE regarding the digestive system? O A. In the stomach, the presence of food produces gastrin, which leads to a lowering of pH, which then activates pepsin for digestion of proteins. OB. As food passes through the liver it is mixed with bile which breaks large clusters of fats into smaller droplets. OC. Nutrient absorption takes place primarily in the small intestine. OD. Lipases in the small intestine break lipids into glycerol and free...
