Homework Answers
1. Oxidation is the loss of electrons. Answer -2
2. carrier-mediated transport can also be a active transport. Answer-4
3. Chemical breakdown and propulsion of food (towards small intestine) occurs in stomach. Due to presence of enzymes and HCl. Mechanical breakdown occurs in mouth. Absorption in small intestine. Defecation through anal canal. Answer is 1 and 5.
4. Rate of gastric emptying depends on meal temperature, content of dietary fiber, particle size of the food, meal volume.
5. CCK (cholecystokinin) relaxes proximal stomach which inhibits gastric emptying. Answer is 3.
6. Gallbladder secretes bile for fat digestion. Bile is synthesized by liver. Answer is 2.
7. Majority of absorption occurs in small intestine. Digestion occurs in stomach. Large intestine absorbs only water and electrolytes. Answer is 2.
8. Circulatory system helps in circulation of water-soluble nutrients to the liver.
Lymphatic system helps in circulation of fat-soluble nutrients away from endocytes.
Urinary system helps in excretion of cellular waste.
Digestive system breaks down and absorbs nutrients from the diet.
9. Disaccharides are sucrose, lactose, maltose.
Monosaccharide are glucose, fructose, galactose.
Polysaccharide are amylase, glycogen, fiber.
Oligosaccharide sucrose, lactose, maltose.
10. Pectin is soluble fiber.
Psyllium is soluble fiber.
Insoluble fibers increase the ability of food passage.
Soluble fibers lower the cholesterol level.
11. Insulin and glucagon regulate blood glucose level. Insulin lowers blood glucose level while glucagon increases.
