Macromolecules:
Carbs - provide energy for cells - 2 types of carbohydrates exist, simple sugars (monosaccharides) and polysaccarides Starch - type of polysaccharides - energy storage for plants Lipids - store energy, create cell membranes, and are used in cell signaling - fatty acids are used for energy storage and are the most effective method for storing energy - saturated and unsaturated fats exist, with the only difference being an unsaturated fat having a double carbon bond where a saturated has a carbon hydrogen bond Nucleic Acids - DNA and RNA - DNA is the genetic code of cells located inside the nucleus of eukaryotic cells - several types of RNA which have various functions including protein synthesis and transferring of information in the cell - both DNA and RNA are made of nucleosides, which are nucleotides (A,T,C,G for DNA, and A,U,C,G for RNA) attached to a sugar phosphate. (these create the helix formation) Protein - created from 20 amino acids - consist of one or more chains of amino acids |
Reflection:
During this lab I learned many things. One thing I learned was that creating cheese was more complicated than I originally thought, as the cheese we created was nowhere close to the level of commercially sold cheese. Another thing I learned was that some cheese takes an enormous amount of time for a small quantity. Using just the milk and water as the curdling agent, it took over a day to create an amount of cheese of just 1,400 mg. Things that I could have done better were staying on task and following the procedure better. During this lab, there were many tiresome parts which caused me to get distracted, losing time I could have used to finish the lab. |
