Unit 2 Reflection

In Unit 2, we learned basic Chemistry and the particles of an atom: Nuetrons, Protons, and Electrons. The atoms are then combined to form molecules or bonds. This includes Covalent bond which shares electrons while Hydrogen bonds spreads electrons. Also we learned the 4 basic parts of living things Carbohydrates, Proteins, Lipids, and Nucleic Acids, their functions and how they help our life. Carbohydrates store energy for producers and having rings of Carbon, Hydrogen, and Oxygen, while Lipids also stores energy and are made of fatty acids. Proteins are made of amino acids, and are in all of our everyday foods we eat to help surrive, and Nucleic Acids carries genetic info., DNA and RNA, across our body so that our body is able to function normally. Finally, Enzymes are catalysts that give complex reactions on our life. With activation energy on Enzymes, the reaction is slower whereas without the activation energy on Enzymes, the reaction is faster.  We found out that the substrate of an enzyme is where the enzyme reacts. In the Cheese Lab, the substrate was the dried milk and the enzyme was the curdling agent for making cheese which was either, Chymosin, or Renin. I found out that I am very familiar with Carbohydartes, Proteins, LIpids, and Amino Acids, but I have to understand the parts of an Enzyme and the kinds of bonds.
