Figure 16.7 Which of the following statements about the digestive system is false? a. Chyme is a mixture of food and digestive juices that is produced in the stomach. b. Food enters the large intestine before the small intestine. c. In the small intestine, chyme mixes with bile, which emulsifies fats. d. The stomach is separated from the small intestine by the pyloric sphincter.
Figure 34.11 Which of the following statements about the digestive system is false? Chyme is a mixture of food and digestive juices that is produced in the stomach. Food enters the large intestine before the small intestine. In the small intestine, chyme mixes with bile, which emulsifies fats. The stomach is separated from the small intestine by the pylloric sphincter.
How does the digestion and absorption of fat differ from that of carbohydrates? Absorbed fat first enters the lymphatic system, whereas carbohydrates directly enter the blood. Fat absorption occurs in the stomach, whereas carbohydrates are absorbed from the small intestine. Only fat must be worked on by bacteria in the large intestine before it can be absorbed. Carbohydrates need to be emulsified before they can be digested, whereas fats do not. Processing of fat does not require any digestive enzymes, whereas the processing of carbohydrates does.
Which of the following is not one of the major functions of the liver? produce bile salts to emulsify fats break down old red blood cells produce blood plasma proteins like albumin and fibrinogen maintain blood glucose levels through the release of insulin and glucagon produce urea from amino acids and ammonia
Which of the following vitamins is synthesised in the body by intenstinal bacteria? A. vitamin B1B. vitamin B4C. vitamin DD. vitaminsK
The stomach has two types of exocrine cells, chief cell which secrete an inactive form of the protein degesting enzymes pepsinogen, and parietal cells , which secrete hydrochloric acid that activates pepsinogen.Both cell types have an abundance of mitochondria ATP production.The chief cells need energy to synthesise pepsinogen and parietal cells need energy to transport hydrogen ions and chloride ions from the blood into the stomach lumen.Only one of this cell types has an extensive roung endoplasmic and abandant Golgi stacks. Would this be the chief cells or parietal cells?why?
Which of the following statements is TRUE? Hydrochloric acid makes an acidic environment in the stomach that promotes promotes polysaccharide digestion. Lipase, produced by the pancreas, digests the emulsified fats into fatty acids. Bile, synthesized by the liver and stored in the gall bladder, digests fats which will then be absorbed in the small intestine The acidic environment converts the inactive pepsin into its active form: pepsinogen. Pepsinogen digests proteins in the stomach.
How does the digestion and absorption of fat differ from that of carbohydrates? Group of answer choices Processing of fat does not require any digestive enzymes, whereas the processing of carbohydrates does. Fat absorption occurs in the stomach, whereas carbohydrates are absorbed from the small intestine. Carbohydrates need to be emulsified before they can be digested, whereas fats do not. Most absorbed fat first enters the lymphatic system, whereas carbohydrates directly enter the blood.
Which of the following is/are TRUE about where the following macromolecules are digested and absorbed by the body? -Carbohydrates are digested by enzymes in the mouth and the small intestine and are absorbed in the small intestine -Three of these answers are correct -Proteins are digested by enzymes in the stomach and the small intestine, and absorbed in the small intestine -Water is absorbed in the stomach and reabsorbed in the large intestine -Two of these answers are correct
Which of the following is True?a. Most fat-soluble vitamins serve as coenzymes.b. Water-soluble vitamins are vitamin C and the B complex vitamins.c. Water soluble vitamins accumulate in adipose tissue.d. Most vitamins can be synthesized by the body.
Which of the following is true of an incomplete digestive tract? Food moves in one direction as it is processed. Both a mouth and anus are present. It can be specialized for digestion in different groups of animals based on diet. A single opening functions in ingestion and eliminaton.
Digestion begins in the mouth. Which of the following statement is INCORRECT? The tongue aids in the digestion of the food. The saliva changes some of the starches in the food to sugar. The tongue keeps the food in place in the mouth while the food is being chewed. The digestive juices can react more easily with the food when chewed.
