24. Know where each of the following organic compounds is digested in the human (also think about where each begins digestion & finishes digestion) – carbohydrates, lipids, nucleic acids, and proteins. Carbohydrates: Digestion begins in the mouth and continues in the small intestine. Lipids: Digested in the small intestine. Nucleic acids: Digested in the pancreas. Proteins: Begin digestion in the stomach, and continue digestion in the small intestine. The small intestine is the major organ of digestion and absorption * (*Bolded for emphasis.) 25. High levels of bad cholesterol (LDL) and low levels of good cholesterol (HDL) are associated with a diet rich in? Trans fatty acids. 26. The ordeal by rice used in courts in Burma and India is based on the fact that fear prevents the secretion of? Amylase from the salivary glands. 27. What are the following enzymes used for? Amylase, lipase, Pepsin, protease. Amylase: Secreted by the salivary glands to aid in digestion, and breaks down starch. Lipase: breaks down lipids into fatty acids and glycerol. (WTF is glycerol?) Pepsin: pepsin is a protease that breaks down proteins into fragments called peptides. Protease: Breaks down proteins into amino acids. 28.What (if any) are the relationships between digestion and stress? [Hint: see Fight or Flight Response studies]. When the secretion of gastric juices in the stomach and saliva in the mouth is under nervous control, the mechanical movements of the stomach are also under higher-level control . “fight or flight.”   *In the fight or flight response, the heart and skeletal muscles are preferentially activated and the smooth muscles composing the digestive tract are turned off. The whole body works together to maintain homeostasis.
