Today and yesterday, the Omega science lab performed an experiment that shows us how our stomach works. There were two days that were factored in this lab. On day one, we watched for immediate reactions when the components of each test tube went together. The components were; boiled egg whites, diluted hydrochloric acid, and chicken tenderizer( a pepsin). On day two, we looked to see if there were any long term effects on the components. Each test tube had a different combination or quantity of our components.
Day 1
On day one, there were no immediate reactions when each of the test tubes components were put together. However, when we checked if a mixture of components were acidic, all the test tubes that had hydrochloric acid showed signs of acid in them. This tells us that hydrochloric acid is a, well....acid!
Day 2
On day two, we could definately see that there was a change. The test tubes that had one component( water, acid, pepsin) and egg whites did not show any signs of change. However, the test tube that had all those components did show signs of broken down egg whites.
As you see, in order for food to digest, there must be both a pepsin and hydrochloric acid working together, because without one, nothing will happen.
