What knowledge have you connected with past knowledge?



In a pervious blog I mentioned that biology and chemistry are taught to students early in their scientific careers because it allows for a broad knowledge base. Having taken both biology and chemistry I often recognize concepts relevant to biochemistry.

Chapter 6 of our text “Protein and Enzymes” discusses the principles of thermodynamics which is a core topic in General Chemistry classes. I can remember learning these principles and found it challenging to grasp the concepts while in Gen. Chem. Today concepts such as activation energy, exergonic and endergonic reaction, and reaction rates are easily absorbed as I have a base knowledge. Biochemistry also allows us to connect these concepts to life processes. This allows me to conceptualize the information making it easier to get the big picture rather than a concept.

Chapter 8 of our text “Lipids and Membranes” directly correlates information I have discussed in detail while in anatomy and physiology. The phrase “structure depicts function” was repeated over and over again while in A&P, and is a concept I will continue to keep in mind while in biochemistry. The structure of the phospholipid bilayer membrane determines its function and ability to isolate the cell while allow certain molecules to pass through. The membrane of the cell performs many tasks, because of this many reaction take place to accomplish these task. While in A&P pathways were identified and discussed. In biochemistry we will build upon the base knowledge we have obtained to dig a little deeper.

As a science student I relate many of the classes to layers of an onion. Biology and chemistry we learn major concepts, and with each additional class we seem to pull another layer of the onion off, getting more and more detailed as we continue.
