A student in lab is trying to use an enzyme to obtain a reaction product . After several attempts , the enzyme reaction continually fails . Using what you know about some factors that affect enzyme function , you ask the student questions to determine what has gone wrong . List three questions you would ask , and why these questions ( and their potential answers ) are important to determine why the reaction is not happening.

You are a scientist working in a lab on a project to create starch from maltose.  You have two tubes of identical, aqueous solutions, reactants, you regularly use in your work.  You have labeled them with labelling tape and know that only one of them contains your enzyme and the other contains another solution. You were away from the lab for the weekend when the air conditioning failed in your lab and the labels have fallen off of your two identical aqueous tubes.  You are unsure which is your enzyme of interest.  Using the concepts of enzyme and the DNS methodology for visualization of the carbohydrate macromolecule, utilized today in lab, please write testable hypothesis to assign identity to the two tubes.   H0:     HA:
