In an graph above which of the following best explains why c

In an graph above, which of the following best explains why curve B (middle curve) reaches Vmax? a. Despite high concentrations of the inhibitor ATP present, there is also enough of the activator AMP to ensure enough of the enzyme is in the R state to reach Vmax. b. There is enough AMP to act as a substrate for catalysis. c. This enzyme will not work unless AMP is present. d. ATP has a weak affinity for the regulatory so ATP does not interfere with the reaction. Liver cells contain GLUT2 transporters on its cell membranes in addition to the GLUT1 and 3 transporters that are found in all cell membranes. Which of the following is true? a. GLUT2 transporters most likely have a poorer affinity for glucose than GLUT 1 and 3 transporters. b. The GLUT2 transporters serve to regulate the blood glucose levels. c. All of the statements are true. d. GLUT2 transporters are bidirectional. What type of enzyme catalyzes the reaction shown? a. hydrolase b. dehydrogenase c. lyase d. isomerase

Solution

40) the reaction is a Lyase reaction because Lyase is a enzyme which catalyses the removal of the the group from the molecules..!! In the above reaction also the hydroxyl group is being removed resulting in the formation of double bonds..!!

39) the answer is GLUT-2 Transporter is a systemic regulator of blood glucose level It can detect the detect the blood glucose level and can work upon different functions to maintain it..!!
