Common Medical School Interview Questions
Here are Medical School interview questions and answers for freshers as well as experienced candidates to get their dream job.
1) Explain what is protein made up of?
Proteins are made up amino acids, and a long chain of amino acid is needed to make proteins.
2) What are the different structures or shapes of protein?
Protein structures are classified into four
3) How many amino acid makes one protein?
To make one protein you require 21 amino acid.
4) What is an amino acid made up of?
Usually, an amino acid is made up of following things
- A hydrogen atom (H)
- A carboxyl group ( -COOH)
- Amino group (-NH2)
- A ‘R’ group or variable
5) Explain what is ‘R’ in amino acid?
‘R’ group is any hydrogen or carbon chain that is bonded to the alpha carbon. Among 21 amino acid which makes protein, 6 amino acid has just a hydrogen atom in the position of the R –group.
6) What determines the structure of protein?
The primary structure of polypeptide in protein determines the primary, secondary and tertiary structure of proteins.
7) Explain what catalase enzyme is and what is the function of it?
Catalase enzyme are large specialized protein molecules, which prevents the formation of radicals which are reactive molecules and cause DNA mutation which cause cancer. The primary function of catalase enzyme is the rapid breakdown of hydrogen peroxide.
8) What is the science behind the hair becomes white or grey with ageing?
Melanin pigment is responsible for the hair colour, and research as shown that hydrogen peroxide interferes with its functioning. With aging catalase enzyme production diminishes which regulates the breakdown of hydrogen peroxide. When there is an excess accumulation of hydrogen peroxide in tissues it will cause de-coloration or whitening of hairs.
9) List out the factors that affects the enzyme activity?
The factors that affect the enzyme activity are
10) What is the primary role of metabolic enzymes? Where it is produced and how you increase it naturally?
The primary role of metabolic enzymes is to repair and rebuilding damaged tissues in your body also to eliminate the undigested food. It is secreted in the pancreas, and you can increase it secretion by eating raw foods and with moderate exercise.
11) Explain what is channel protein? Give an example where you will find channel protein?
Channel protein are like gates that opens and close depending on the concentration gradient across the cell membrane; it enables to transport protein and other larger bio-molecule which otherwise unable to transport through the membrane of the cell.
Potassium channel is one such example of membrane protein, which allows the K+ (potassium charges) and generates an electrical signal which facilitate the nerve impulse to propagate in the nervous system.
12) Explain what does CCBs (Calcium channel blocking agents) do? Give some example?
Calcium channel is blocking agents or drugs that blocks the calcium ions across the cell membranes by blocking the L-type channel. These drugs are prescribed to patients who are suffering from hypertension. They are classified into three groups.
13) What is the function of plasma membrane CA+2 ATPase?
Plasma membrane Ca+2 ATPase is a transport protein in the plasma membrane of cells, it acts like a pump that does the function of removing of CA+2 ions from the cells. When the function of this pump hampers it causes diseases like hypertension, diabetes and sensorineural diabetes.
14) Explain what is micro-tubules?
A filamentous intracellular structure that are responsible for various kinds’ protein and vesicles movement in all eukaryotic cells are known as micro-tubules. They are the main structure of the cytoskeleton in cells.
15) Explain what is the technique used to detect protein concentration?
To detect protein or other bio-molecules, mass spectrophotometry is used. It works on the principle of light absorption method. This instrument measures the amount of light of a specified wavelength. Moreover, the amount of light absorbed by the medium is directly proportional to the concentration of the bio-molecules or protein.
16) What is anti-body made up of? What are the different types of anti-bodies?
Anti-body is a protein, like majority of protein, this protein is also made up of more than one polypeptide. They are also referred as binding proteins and are very specific for a specific ligand known as antigen.
They are classified into
17) Explain what is HPLC?
HPLC stands for High Performance Liquid Chromatography; it is an equipment and method which is used to separate bio-molecules according to their size. In this technique, a pressurized liquid along with sample is allowed to pass through a column filled with sorbent. Moreover, the bio-molecules will be separated according to the interaction with the sorbent.
18) Explain what are Cytokines?
Cytokines are special types of non-antibody that act as mediators between cells. Their role is believed to be in boosting immunity but recently it is discovered that other than immune cell they also have effects on non-immune cells.
19) What are the different types of Cytokines?
Different type of Cytokines are
20) Give detail about IgG antibody?
IgG anti-body is the main anti-body in blood. It is the only anti-body that pass through the placenta, and it through placenta it is transferred to the mother’s body and protects the new-born until a week after birth. It is widely distributed to the blood and tissue.
21) Explain what are Chemokines?
Chemokines are one of the cytokines types, which are produced by many kinds of leucocytes and other cell types. It represents the group of family of molecules that does the function of recruiting leucocytes to the infection sites.
22) Mention the cytokines that play a significant role in the adaptive immune system?
23) Explain what are T-cells?
T-cells are the type of white blood cell that circulate into our bodies, which scans for infections and cellular abnormalities.
24) What are the primary functions of T-cells?
The primary functions of T-cells are
- Kill cells infected by virus or bacteria
- Naturally kills cancer cells
- Scans intracellular environment for foreign invaders
- Activate other immune cells or molecules
25) Explain what is Interleukin 6?
Interleukin 6 is also a cytokine; macrophages and T cells secret it. It acts as a pro-inflammatory and anti-inflammatory cytokines. It becomes activated when there in an information within body and outside body. Interleukins are referred as IL.

A stroke is referred for brain attack that occurs when there is a blockage or interruption of the blood supply to part of the brain.
There are two types of strokes
- Ischemic stroke: This type of stroke occurs due to an obstruction within a blood vessel supplying blood to the brain
- Haemorrhagic stroke: This type of stroke happens when a weakened blood vessel ruptures and spills blood into brain tissue.
47) Explain how ECG (Electro Cardio Gram) nodes are represented?
ECG machine will show five waves PQRST
- P Wave: It represents the normal atrial depolarization ( contraction of atria)

Prednisolone is one of the examples of Glucocorticoid drugs; they are one type of steroid. This drug is used for the treatment of many diseases like multiple sclerosis, inflammatory bowel disease, rheumatoid arthritis, ulcerative colitis, inflammation etc. Normally, the human body makes glucocorticoids in form of cortisol, whose primary function is to stop information, but when there is excess need of cortisol to cure chronic inflammation, a synthetic glucocorticoid is provided.

There are two ways elephantiasis can be infected
- Lymphatic Filariasis: It is caused by a worm known as wuchereria bancrofti parasite and is transmitted to human through mosquito bites
- Non-filarial elephantiasis: This type of elephantiasis is more seen in central African region, and this occurs due to the chemical present in the volcanic ashes.
In both types of infection, they attack lymph nodes, often caused by an obstruction of lymphatic vessels, resulting in swelling of skin and tissue.
