A sample of a Cellobiose solution is incubated with with the
enzyme Cellobiase for several hours and the then tested using the
DNS-reagent assay (3,5-dinitrosalicylic acid) and determined to
have a concentration of 2.2 mM. If the initial Cellobiose solution
(i.e. not treated with Cellobiase) is tested with the DNS-reagent
assay what concentration would be measured?

2.2 mM

no reaction, inconclusive

1.1 mM

4.4 mM
