1. Which of the following organ stores bile? spleen stomach gallbladder pancreas small intestine 2. The small intestine is divided into the duodenum, jejunum, and ___. sigmoid fundus ileum pylorus cecum 3. Mastication of food is an example of ingestion. secretion. absorption. chemical digestion. mechanical digestion. 4. Which of the following is an accessory organ of the digestive system? esophagus stomach cecum pancreas duodenum 5. The mucosa of the large intestine contains cells that absorb monosaccharides. triglycerides. water. amino acids. disaccharides. 6. 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. Which of the following vitamins are not absorbed along with dietary lipids? Vitamin A Vitamin C Vitamin D Vitamin E Vitamin K 7. The chemical breakdown of one glucose molecule into two pyruvic acid molecules is called ___. lipolysis glycolysis ketogenesis oxidative phosphorylation glycogenolysis 8. The Krebs cycle occurs in this organelle. nucleus ribosome endoplasmic recticulum mitochondrion Golgi complex 9. Which of the following is NOT a mechanism of heat loss? propagation radiation conduction convection evaporation 10. Chemical reactions that break down complex organic compounds into simple ones are called catabolic reactions. True False
The breakdown of complex glycogen molecules into simple glucose molecules is most accurately described as a anabolic reaction.
One theory for long-lasting immunity assumes that humans are continually exposed to the disease-causing agent. Explain how this exposure could produce lifelong immunity.

Studies on the global climate cycle have revealed a %u201Cmissing%u201D carbon sink (i.e., carbon being taken from the atmosphere and put into the biosphere) of approximately 3 GT/year (thought to be an underestimate of the size of the photosynthe..
While two monohybrid round squashes are crossed, the offspring ratio is ¼ flat, ½ oblong, ¼ round. Squash shape is therefore controlled by incomplete dominance. What offspring ratio would you expect from a cross between a plant with oblong fruit and ..
