Question

the liver by HDL 17. Ir you have been on a J-day hunger fast to protest the lack of gen control laws in this country.you a. synthesize glycogen in muscles and in the liver b. convert excess glucose into triglyeerides and release the triglyceride as Vi c, transport ehylomicrons to liver and muscle cells d, increase the amount of ketone bodies in your blood e. have lower insulin levles, whieh would inhibit glaconeogenesis 18. An injection of a large amount of insulin in your body would cause a decrease in free fatty acids and glycerol in your blood e. a stimulation of glycogenolysis d. a decrease in glucose entry into c e, an increase in glyeerol and free fatty acid release from fat cells 19. A water molecule bonding to another water molecule is an example of: a, an ionic bond b, at hydrogen bond e, a covalent bond d. a van der Waals interaction Sado-Machochistic (S& M) bonding 20. All of the following molecules are lipophobic except: a. carbon monoxide (CO b. the amino acid alanine c. chloride ions d. water molecules e. adenosine triphosphate 21 All of the following about secondary active transport are true except these active transport pumps do not require ATP for energy b. these pumps use the diffusion of sodium ions to provide energy for active transport c. in intestinal enterocytes, these pumps actively transport glucose into the cell d. some of these pumps actively transport amino acids into the cell e. an example is the sodium/potassium pump, found on the basolateral side of enterocytes 22. Which statement about glycogen is false? increased glycogenesis usually occurs during increased gluconeogenesis b. during fasting, glycogenolysis occurs c. low insulin levels are associated with glycogenolysis d. during fasting, glycogen stores generally last about 12 to 24 hours e. high insulin levels are associated with low glycogenesis 23. Which of the following about carbohydrate digestion is false a. because glucose is large and polar, it must be exocytosed from the enterocyte into blood vessels b. in the liver, excess carbohydrates can be converted into triglyceride, and released as VLDL c. some carbohydrate digestion occurs at the brush border membrane of the intestinal enterocytes d. glucose is actively transported into enterocytes at the luminal (Gintestinal) side of the cell e. most of carbohydrate digestion occurs through salivary amylase combined with pancreatic amylase All of these statements about insulin action are true except a. an increase in blood glucose stimulates insulin release from pancreatic alpha cells b. insulin binding with its receptor causes an increase in the number of glucose carriers on cell membranes not require insulin in order to absorb glucose from the blood d. increasing inulin causes intracellular vesicles containing glucose carriers to fuse with the cell membrane e. an increase in insulin increases the diffusion of glucose from the blood into the cells

Answer 1

17. d) increase the amount of ketone bodies in your blood. During starvation or fasting, ketone bodies are formed as a result of intense gluconeogenesis. Glucose are needed for energy during starvation, therefore it is formed in liver from stored fatty acids. Ketone bodies are the byproducts.

18. a) A decrease in free fatty acids and glycerol in your blood. Fatty acids and glycerol are absorbed by cells for synthesis of triglycerides.

19. b) a hydrogen bond.

20. a) carbon monoxide (CO).
