- Meat is composed primarily of protein and fat. Which statement is false? meat does not contain fiber O meat cannot be digested, and rots/ferments in the stomach O lipase digests parts of meat O pepsin, trypsin, carboxypeptidase, and chymotrypsin digest parts of meat O HCI helps to unravel the meat proteinsHow does the digestion and absorption of fat differ from that of carbohydrates? O Carbohydrates need to be emulsified before they can be digested, whereas fats do not. O Processing of fat does not require any digestive enzymes, whereas the pro ing of carbohydrates does. O Fat absorption occurs in the stomach, whereas carbohydrates are absorbed from the small intestine. O Most absorbed fat first enters the lymphatic system, whereas carbohydrates directly enter the blood.If someone develops maltose intolerance, what wouldbe true about that person? 1-They have a deficiency in the brush border enzyme names maltase 2-Thet have a deficiency in pancreatic amylase, the enzyme that converts oligosaccharides to mlatose 3-They need to minimize the amount of lactose they ate 4-They should eat more srach to have moremaltose in their digestive tract
- Both the esophagus and the small intestine are involved in the digestion of food. The esophagus squeezes food into the stomach by wave-like muscle contractions. Peptidase enzymes in the small intestine break food molecules into smaller molecules. Which statement best describes changes to food during digestion? O The muscle contractions result in physical changes, while the action of the peptidase results in chemical changes. O The muscle contractions and the action of the peptidase both result only in physical changes. O The muscle contractions result in chemical changes, while the action of the peptidase results in physical changes. O The muscle contractions and the action of the peptidase both result only in chemical changes. 8. 9. 10 11 12 13 14 15 16 17 20 近Proteins are digested in the alimentary canal into amino acids. Amino acids move into the blood from the small intestines. Those amino acids are used to synthesize new proteins in our body cells. This last step is an example of ... O Assimilation Absorption O Digestion O IngestionDuring digestion, mechanical processing of food is followed bya. enzymatic hydrolysis of foodb. absorption of nutrientsc. absorption of enzymesd. elimination of undigested material
- In cases of extreme emergency when the upper air passageway is blocked by a foreign object to the extent that the victim cannot breathe, quick reaction is required to save the person's life What procedure is designed to force such an object out of the air passage by the sudden application of pressure to the abdomen?

Which part of the digestive system is it in? The mouth O The jejunum O The esophagus The rectum The duodenum O The stomach
- Select ALL of the following that pepsin, trypsin, and chymotrypsin share in common: V they all digest proteins into peptides they are all enzymes they are all located on the brush border O they are all secreted in an inactive form O they are all produced by the pancreas O they are all proteases they are all activated by HCI (hydrochloric acid) O they must all be activatedDo you think unprocessed food is easy to disgest than processed foods and why?Which of the following statements about protein digestion are true? Check all that apply. ► View Available Hint(s) Pepsin is active only in an acidic environment. Hydrochloric acid in the stomach denatures proteins and activates some enzymes. The tertiary and secondary structures of proteins unfold due to the action of the enzymes in the gut. Most of the hydrolysis of polypeptides takes place in the small intestine. Some proteins are broken down into amino acids by the process of chewing. The primary structure of a protein is destroyed by hydrolysis. K
