Question

You have two tubes that initially contain the same amount of starch. However, you add one microgram (1 ug) of amylase enzyme to Tube B and let it sit for 7 minutes. The resulting absorbances are 0.52 for Tube A and 0.26 for Tube B. What is the remaining starch concentration in Tube B? Enter only the numerical response (not the units) to one decimal place.

Answer 1

what do u mean by remaining starch conc?

Answer 2

There's a graph that has starch concentration on the x axis and absorbance on the y axis and there is a standard curve plotted. It asks for the initial concentration in one question and the final in the other and I don't know how you would no which point to choose based on this

Answer 3

here's the graph

Answer 4

I figured it out. The initial concentration is 10 because it should be the same as tube A which lacks the enzyme breaking down the starch. And the final concentration is 5. The concentrations come from the correspondence with the absorbance on the graph

Answer 5

srry i dozed off yest..so cudnt rply..:(
