What knowledge have you connected with past knowledge?

I have connected much of my knowledge from previous classes with the new information we are learning. I have learned quite a bit of knowledge about enzymes in previous classes. I knew that they increase reaction rate but I was unaware of how they do this and how much they are actually speeding up the reaction. I also learned alot about different types of bonding such as hydrogen, covalent, etc. I did not know the application of these types of bonding except for different molecules using these to bind to one another. I did not know that proteins use these types of bonding. For example, the alpha helix has hydrogen bonds and these bonds hold the structure of the protein in the alpha helix. If these hydrogen bonds were not there the structure would change and would result in a change of the function of that protein.
