The truth is that the choice of the "zero" point for height is arbitrary, and it's usually done to simplify the problem at hand. Whenever you calculate GPE, you're really more concerned about gravitational potential energy changes rather than any sort of absolute measure of the sto...
In this lab we explore an enzymes activity and how it can be affected by changes to its environment. An enzyme is a protein and is a catalyst to chemical reactions (Raven, 2011). It helps accelerate reactions by lowering the activation energy, which is needed for reactions in cells to pro...
