2.How does hydrochloric acid aid in the digestion of food? Read and analyze the question and choices CAREFULLY; more importantly, ALWAYS CHOOSE the BEST answer. Hydrochloric acid initiates carbohydrate and protein digestion in the stomach. Hydrochloric acid is the gastric juice that stops lipid digestion in the stomach. Hydrochloric acid does not really participate in the digestion of food; however, the acidic environment due to HCl activates pepsinogen which will be converted into pepsin that breaks down peptide bond between amino acids in a polypeptide. Hydrochloric acid breaks down the peptide bonds, glycosidic bonds, and acid anhydride bonds among proteins, carbohydrates, and lipids respectively.

9.How does gastrointestinal tract evade dehydration? Read and analyze the question and choices CAREFULLY; more importantly, ALWAYS CHOOSE the BEST answer. Water is an important digestive enzyme in the stomach. Alternating wave-like contraction and relaxatio of the oral (mouth) muscles reabsorbs water which will be transported to the urinary system The water we drink will be mostly absord by the blood vessels attached to the esophagus and stomach. Normal peristaltic movements in the large intestine ensure reabsorption of water that will be delivered to the circulatory system.
6.Which of the following statements is TRUE? Read and analyze the question and choices CAREFULLY; more importantly, ALWAYS CHOOSE the BEST answer. Saliva makes an acidic environment in the stomach that promotes polysaccharide digestion. Bile, synthesized by the gall bladder and stored in the liver, 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. The small intestine is divided into 3 sections: duodenum, jejunum, and ileum
Which of the following is TRUE? The substrate for lipase is fatty acids When lipase is present and active it hydrolyzes triglycerides When triglycerides are hydrolyzed the pH would be elevated All of the above None of the above
7. Some people go into HIGH-FIBER DIET. Fiber is made of complex carbohydrates plus some proteins. It stimulates good digestion. Also toxic substances such as carcinogens (substances that causes cancer) and bad cholesterol bind with fiber and thus will be excreted. It comes in two forms, soluble and insoluble fiber. Soluble fiber specifically binds water well, increasing the feeling of a full stomach (nakakabusog agad). By researching, give 3 foods that contain soluble fiber and 4 foods that contain insoluble fiber.
1. You just ate 2 slices of cheese pizza for lunch. Describe how the lipids are digested, absorbed, and transported to your body's cells. Be sure to include digestive tracts, accessory digestive organs, enzymes, etc.
1. Carbohydrate digestion: gastrointestinal enzymes and the optimal pH environment for their activity.
Which has the highest coefficient of digestibility? Carbohydrates Lipids Sugar Proteins
During digestion we produce energy by converting large complex molecules into smaller simpler molecules. During this process what best describes the changes in energy? 1. Stays the same 2. Increases 3. Decreases 4. Increases then decreases
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.
The ingestion of a meal high in fat would cause which of the following to occur? bile would be released to emulsify the fat severe indigestion caused by lack of sufficient digestive enzymes the acidic secretions of the stomach would be sufficient to completely digest the food
The phrase "dietary amino acids are absorbed during digestion" is used to describe when: Amino acids are cleaved apart by different enzymes within the digestive tract. Amino acids are transported from the intestinal lumen into the intestinal cells. Amino acids form hydrogen bonds with water in the environment. Amino acids bind to taste receptors on the surface of the tongue.
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.
