Q1. Glucose is added to cells and the rate of glucose transport is plotted against glucose concentration. In the presence of the galactose derivative 6-O-benzyl-D-galactose, the curve is shifted to the right. What variety of agent is 6-O-benzyl-D-galactose? Q2. Clarify the roles of transpiration and “pushing” from water pressure in […]

What are the different phospholipases that act to hydrolyze the ester linkages of the groups attached to the various carbon atoms of glycerol? At which carbon atom of glycerol are you most likely to have arachidonate bound? Which of the phospholipases releases arachidonic acid? Which phospholipid is likely to have […]

You have isolated five yeast mutants (a – e) unable to metabolize galactose. All of the mutants fail to transcribe the GAL2 gene, which encodes the enzyme for the first step in metabolizing galactose. You want to determine whether each mutant isa cis-acting mutation of a regulatory sequence for GAL2 […]
