GAMSAT Sec 3 Biochemistry – Syllabus and Question Solving

Why is Biochemistry Essential?

Biochemistry is one of the core areas of biology; its study has thrown light on a large number of scientific discoveries in medicine and pharmacy. This is why aspirants with expertise in biochemistry perform increasingly well in GAMSAT. In Biochemistry, you get to study a great deal about the complex processes occurring in different organisms right from bacteria to humans. You also learn about the molecular basis of the structure and processes of life. The knowledge of the subject plays a vital role in the field of pathology as well. As for example, it is very essential in analysing blood and urine samples taken from patients suffering from a wide range of diseases. The intricate operating systems in our body can all be studied via this branch of science.

Biochemistry has a lot of scope, for instance a combination with immunology forms an exciting amalgamation in science that provides the medical students with new ways to fight against a range of diseases including the most dreaded ones  such as arthritis, HIV and cancer, to name a few.

Biochemistry Syllabus in GAMSAT Section III

While preparing for GAMSAT Section III make sure you start with acquiring the fundamental knowledge of structures and functions of different types of carbohydrates, proteins and lipids. Going through an assortment of GAMSAT preparation courses and GAMSAT sample papers will help to build up your ability to clarify the link between biochemistry & the molecular basis of health and disease and help you to answer GAMSAT questions with ease.

ACER instructs you to keep abreast of first year University Level Biology and Chemistry syllabus where some topics show up as hotspots for GAMSAT Sec 3:

  • Cellular Metabolism
  • Glycosis
  • TCA Cycle
  • Kreb’s Cycle
  • ATP and Glucose as Energy Sources
  • Aerobic Respiration
  • Anaerobic Respiration
  • Regulation of Pathways- Feedback Regulation, Product Inhibition, Positive and Negative Regulation
  • Forms of Energy Stored in Biological Compounds
  • Electron Transport Chain
  • Carbohydrate Metabolism
  • Lipid Metabolism
  • Protein Metabolism


Question Pattern

Questions in Biochemistry come in the form of flowcharts, where analytical techniques and logistic justification get tried on for size. Let’s take a look at the flowchart given below:




  • To answer questions from this vignette, you need to carefully observe for the dependency of one component on the other and how the absence of one of them can affect the pathway.
  • For example, one question from this vignette is: which component here triggers the conversion of inactive protein C to its active functional form?
  • In order to answer this question, you’ve to comprehend from the vignette that thrombin helps in this conversion which is itself under the regulation of factor V.
  • Thus, we may conclude, in the state of factor V deprivation, one can’t form active protein C.

This proves, it’s advisable to go through the entire pathway before you answer a question. In your journey with Biochemistry, not only you need to get clear picture of core concepts, you also need to follow the schematic pathway while deriving conclusion from the given flowchart. Don’t try to swim against the pathway given!

Now that you have got a better idea of where to start, hope that your journey with biochemistry alongside the route of GAMSAT preparations would be satisfying and fruitful. Always remember, mugging up a subject in order to overcome its fear is not a solution. Instead, try and understand it and create a friendship with it in order to have a fulfilling and successful learning experience.
