What knowledge has connected with past knowledge?

       This last half of the semester the knowledge I have connected back to past knowledge has been the concept of chemical pathways in the body and the cycles that produce energy within the cell. With the chemical pathways the review was good because information was gone over that i haven't revisited since first semester freshman year. Understanding the difference between active and passive transport coupled with facilitated transport is key when working with medicines on how to administer the drug  and diseases on how to either treat the disease or dull the effects. Also the knowledge of how the cells produce energy in the form of ATP is crucial in identifying which cells are performing correctly. The presentation I did in class on how to treat cancer with Pyruvate Kinase Isozymes showed that a simple enzyme can make a cell go from energy producing in the form of aerobic metabolism of glucose (citric acid cycle) for the body to anaerobic metabolism using the energy to produce more cancer cells which is harmful to the body. By reviewing these two points it helped better understand the more advanced topics used in class.
