Which of the following is not a function of the large intestine? mucus secretion formation of feces water absorption bacterial fermentation digestion of lipids by intestinal lipase 7. Secretion of saliva is controlled by the uvula. hormones from the tongue's papillae. the autonomic nervous system. the chemical composition of the foods eaten. 8. Which of the following includes all the components of gastric juice? hydrochloric acid and pepsinogen mucus and enzymes mucus, intrinsic factor, hydrochloric acid, and pepsinogen mucus, hydrochloric acid, and enzymes 9. The pancreatic acini produce glucagon. form the pancreatic duct. constitute the exocrine portion of the pancreas. are considered a type of endocrine gland. 10. Which small intestine enzyme and function is mismatched? sucrase: digests sucrose into glucose and fructose peptidase: digests proteins into amino acids ribonuclease: digests DNA lactase: digests lactose into glucose and galactose Week 10 1. Which statement does NOT describe a mineral? Minerals help regulate enzymatic reactions. The mineral sodium is involved in the generation of nerve impulses. Minerals are organic nutrients generally concentrated in the skeleton. Minerals such as calcium, iron, and magnesium are part of some coenzymes. 2. Water-soluble vitamins are absorbed from the digestive tract with dietary lipids. are excreted in the urine if there are excessive quantities in the body. tend to be stored in the liver. include vitamins A, D, E, and K. 3. The function of proteins in lipoproteins is to allow the lipids to be more readily catabolized. convert lipids into triglycerides. help the lipoproteins dissolve in body fluids. alert the body to break down lipids for energy production. 4. During metabolism, enzymes serve as catalysts to speed chemical reactions. some enzymes require the presence of an ion such as calcium, iron, or zinc. anabolic reactions use more energy than they produce. All of these answer choices are correct. 5. The balance between heat production and heat loss is controlled by the adrenal medulla. liver. kidneys. hypothalamus. 6.
