- Which of the following statements regarding glucose is NOT true? a.)Glucose is a monosaccharide sugar b.)Glucose can be metabolized by both aerobic and anaerobic metabolism c.)The normal blood glucose concentration is 4-7 mmol/l d.)A high blood glucose concentration is called hypoglycemiaEating non-fibrous carbohydrates can cause a cycle of glucose dependenceand hunger represented by a glucose crash. Explain this situation showing the levels of insulin and blood glucose under this situationA glucometer measures the electrical current produced by the redox reaction catalyzed by glucose oxidase, which converts gluconolactone to glucose. True False
- True or False c. Glycogen synthase catalyzes the synthesis of α-1,6 linkages. True False d. The activated form of glucose is added to the non-reducing end of glycogen molecules. True FalseThe typical human adult uses about 160 g of glucose per day, 120 g of which is used by the brain. The available reserve of glucose (~20 g of circulating glucose and ~190 g of glycogen) is adequate to sustain the individual for about one day. After the reserve has been depleted during starvation, how would the body obtain more glucose?Only Dextro Sugars are metabolised in our body? True False
- True or False If a person intakes a large amount of water-soluble vitamins, the excess vitamins will be stored in liver for later use.Which carbons of Glucose 1-Phosphate will be incorporated into Lauric acid (C-12) by the Fatty Acid Synthase? (One or multiple answers) a. Carbon 1 b. Carbon 2 c. Carbon 3 d. Carbon 4 e. Carbon 5 f. Carbon 6 g. All carbons will be incorporated. h. No carbons will be incorporatedyou follow a carbohydrate-free diet, certain metabolic problems occur. Describe glucogenesis and the problems that may arise from this prolonged glucogenesis state.
