As the stomach churns DAY 2

    During Day 2 of this lab, many things changed.  For example, in some of the tubes, the white eggs turned bubbly.  The hydrochloric acid was doing it's job.  The acid was digesting and breaking down the egg just like what happens during in a stomach.  We learned that it is necessary for the acid to work with the pepsin or else one substances will be too powerful.  If the pepsin was not in the stomach, the acid would burn our stomach.  We did this lab to understand what really happens in our stomach for it to digest.
