How to prepare for the exam of Biochemistry
One of the most difficult exams that terrifies every year thousands of students is definitely Biochemistry! The examination is characterized by the study of chemical reactions within the human body and the program is mainly topics as biological chemistry, enzymology, systematic human biology, molecular and cellular biochemistry applied. Now let’s see some useful advice to prepare in the best way.
First, know that to better prepare the examination of biochemical need to buy a text that allows you to integrate your notes or study doing without resorting to the same! The book chosen, therefore, should have four main features: to be clear, comprehensive, complete and must follow a logic that allows you to understand the connection between topics. Certainly, one of the most used college texts and that has the characteristics described above, is ” Principles of Biochemistry Lehninger ” by David L. Nelson and Michael M. Cox. Biochemistry, also, should never be regarded as a matter for its own sake, as it is closely connected with the organic chemistry and biology. In fact, being “horse” between these two disciplines, it will be necessary (before preparing the ‘exam!) have a solid foundation of inorganic chemistry and chemical organic, so you can understand all the metabolic reactions. to prepare for the exam only after this you can go to the stage of contextualization of biochemical phenomena, such as glycolysis , the mitochondrial respiration or amino acid catabolism , before applying them at the cellular level and then physiological.
If you do not remember some key topics of general chemistry and organic, try to “rispolverarli”: try to pay special attention to issues such as chemical bonds, the structure of the molecules, water activity etc. , also because it will be essential to understand the later stages of the study of this difficult subject. After that, you focus your attention on the study (or repetition in case you have already discussed these topics in organic chemistry) of macromolecules fundamental , ie lipids, proteins and therefore amino acids, polysaccharides, nucleic acids and so on. In any case, the study will affect not only their structural composition but also their physical-chemical properties. Also try to pay special attention to the study of enzymes and enzymatic catalysis, because it will allow you to understand not only how he is an enzyme but also the energetic phenomena that are the basis of chemical reactions.
So, after studying the ‘general’ part of matter, you’ll have to go to the study of metabolic reactions in living things and control channels that control the biochemical processes. Unfortunately, this is the hardest part …… .but even more interesting examination of biochemistry. To facilitate learning, try before you store jobs (glycolysis, oxidation of fatty acids, gluconeogenesis , etc …), trying to figure out which reactions take place (if esterification, hydrolysis and so on) and then store the structure of the different molecules. If you think you’ve already figured out all the steps of these metabolic reactions, you can move on to the study of the control channels and enzymes involved in the activation or inhibition of a specific reaction: what will make you understand the connections between all metabolic processes and especially because these happen!
Well, the preparation phase of the examination is finished. However, it remains the party, in my opinion, most important, to repeat testing . To help in this stage, try to rewrite all the reactions that you have learned, starting over every time you realize you’ve made a mistake. You can then repeat the fast high-way adjustment …… but not as arguments were detached from the rest, but showing the connection between them. For example, between the processes of inhibition of glycolysis and those for activation of gluconeogenesis .
