A saturated hydrocarbon tends to a. be more liquid at colder temperatures compared to an unsaturated hydrocarbon. b. be more solid at colder temperatures compared to an unsaturated hydrocarbon. c. contain many double bonds. d. contain fewer carbon-carbon bonds compared to an unsaturated hydrocarbon. 48-49. Refer to the figure below. VII VI 48. Which of the following represent the best labels for the x axis and the y axis in the figure? a. X Substrate concentration;y-Reaction velocity b. x Enzyme concentration; y Reaction velocity C. X Time; y Substrate concentration 49. In the figure, which region best represents the Km of the highest affinity enzyme? a. I C. VII d. IV

Explanation / Answer

47. It will be more solid at colder temperature when compared to unsaturated fat.

saturated fats are usually solid at room temperature.

48. a. This kind of graph we usually get when we plot substrate concentration and reaction velocity.

49. VII

Km is half of Vmax.

II enzyme is the enzyme with highest affinity.
