GluT transporters aid in glucose transport into a cell... - -by assisting in the transport of glucose into the cell. Gluconeogenesis is... - -This process produces new glucose and is needed in a fasting state to increase blood sugar, supplying energy to the brain and muscle. Glycogenolysis is.... - -This process is the breakdown of glycogen to release individual glucose molecules. It benefits the fasting state because it increases blood glucose. Where is glucagon made? - -alpha cells of th...

feedback inhibition - -reversiable, noncompetive inhibition of an enzyme in a pathway by a product of that pathway induced fit - -substrate binding causes a conformational change Which type of inhibition occurs when a particular drug binds to the allosteric site of an enzyme and subsequently changes the enzymes structure? - -noncompetive competitive inhibition - -A molecule which competes with the substrate for binding to the enzyme active site there by inhibiting the enzyme's activity. ...

Insulin controls both carbohydrate and fat metabolism. Which of the following statements describes the effects of insulin? - -a. All of these b. Inhibits the glycogen breakdown c. Stimulates the glucose uptake d. Stimulates fatty acid production and storage Insulin is responsible for several controls such as stimulating glucose uptake, inhibiting the glycogen breakdown and stimulating fat storage molecule synthesis. True or False: The defining characteristic of diabetes is the lack of suf...

PCR is a powerful tool that can do all of the following EXCEPT ________. - -b. copy large segments of DNA, greater than 6kb Which of the following is NOT a required "ingredient" in a PCR reaction? - -b. RNA primers CorrectCorrect! RNA primers are used in DNA replication inside the cell, but the quick degradation of RNA makes it less useful for PCR reactions. Instead, PCR reactions contain primers made of DNA to anneal to the region of DNA that will be amplified and serve as a starting poi...
