Question 1
Glycosylated molecules are formed with
◦ cholesterol.
◦ lysosomes.
◦ carbohydrates.
◦ DNA.
◦ nucleic acids.
Question 2
Cells regulate their level of activity by regulating the amount of proteins in the cell at any given time, so an up-regulation of enzymes would be expected to
◦ increase the cell's response produced by the reaction catalyzed by the enzyme.
◦ decrease the rate of reactions catalyzed by the enzyme.
◦ decrease the level of productivity of chemical reactions that rely on the enzyme.
◦ decrease the level of productivity of chemical reactions that rely on the enzyme and decrease the rate of reactions catalyzed by the enzyme.
◦ have no effect on the rate of reactions catalyzed by the enzyme.
