Name the substrate of the chemical reaction you studied in Lab Exercise 4.

Which phase of water is shown below?  

10mm is equal to _______ cm

What is the molecular formula for propane? 

What is the volume of the liquid below? Be sure to include the metric units in your answer.    

True or False: As temperature is increased, the movement of water molecules increases. 

When changing from the 10x objective lens to the 4x objective lens, the field of view will:

Why does Methane have 4 hydrogens?   

In the metric system, another unit name for mL is “cc” (hint: this is commonly used in the medical field).

In Exercise 4, you learned about a reaction that amylase catalyzes. Below, is an example of another enzyme-catalyzed reaction.    Lactase, is an enzyme found in the human body, which is responsible for breaking down lactose molecules. Lactose molecules are found in milk products. Many people are deficient in lactase, which makes them unable to effectively break down milk products. There is a specialized test that can be done to test for lactose deficiency, using blood glucose levels as the indicator. A scientist set up an experiment to test the effect of time on lactose breakdown through this enzyme-catalyzed reaction. In this experiment, the subjects consumed 1 cup of milk, and had their blood drawn every 15 minutes to test their blood glucose level. Give an example of a variable that must be held constant in this experiment.
