[Kiran Chandar]

Here I am giving you AIPMT (All India Pre Medical Test) Previous year question papers with solutions.

Some content of the file has been given here.

1. The cells lining the blood vessels belong to the
category of
(1) Columnar epithelium
(2) Connective tissue
(3) Smooth muscle tissue
(4) Squamous epithelium
Ans. (4)

Sol. Simple squamous epithelium is present where
diffusion and filtration is required. Cells lining our
blood vessels belong to the category of simple
squamous epithelium.

2. Consider the following statements (A-D) about
organic farming
A. Utilizes genetically modified crops like Bt
cotton
B. Uses only naturally produced inputs like
compost
C. Does not use pesticides and urea
D. Produces vegetables rich in vitamins and
minerals
Which of the above statements are correct?
(1) (B) and (C) only (2) (A) and (B) only
(3) (B), (C) and (D) (4) (C) and (D) only
Ans. (1)

Sol. Organic farming is a zero waste cyclical procedure,
where waste from one process are cycled in as
nutrient for other process.

3. Select the correct statement with respect to
diseases and immunisation
(1) Certain protozoans have been used to mass
produce hepatitis B vaccine
(2) Injection of snake antivenom against snake
bite is an example of active immunisation
If due to some reason B-and T-lymphocytes are
damaged, the body will not produce antibodies
against a pathogen
(4) Injection of dead / inactivated pathogens
causes passive immunity
Ans. (3)

Sol. Clone of B-cells is called as plasma cells which
produce antibodies. Helper T-cells secrete IL-2
(interleukin-2) which stimulate B cells to produce
antibodies. Injection of snake antivenom against
snake bite is an example of artificially acquired
passive immunity.

4. Selaginella and Salvinia are considered to represent
a significant step toward evolution of seed habit
because
(1) Megaspores possess endosperm and embryo
surrounded by seed coat
(2) Embryo develops in female gametophyte which
is retained on parent sporophyte
(3) Female gametophyte is free and gets dispersed
like seeds
(4) Female gametophyte lacks archegonia
Ans. (2)
Sol. Both are heterosporous genera; archegonia are
present in both cases.

5. Which one of the following animals may occupy
more than one trophic levels in the same ecosystem
at the same time?
(1) Goat (2) Frog
(3) Sparrow (4) Lion
Ans. (3)

Sol. Sparrow can be herbivorous (eating seeds and
fruits) or carnivorous (eating insects).

6. Which one of the following is essential for
photolysis of water?
(1) Copper (2) Boron
(3) Manganese (4) Zinc
Ans. (3)
Sol. Manganese is the component of OEC that takes up
e– from H2O.

7. What happens during fertilisation in humans after
many sperms reach close to the ovum?
(1) Cells of corona radiata trap all the sperms
except one
(2) Only two sperms nearest the ovum penetrate
zona pellucida
(3) Secretions of acrosome helps one sperm enter
cytoplasm of ovum through zona pellucida
(4) All sperms except the one nearest to the ovum
lose their tails
Ans. (3)

Sol. At the time of fertilisation secretions of acrosome
helps one sperm to enter the cytoplasm of ovum
through zona pellucida.

8. Bulk of carbon dioxide (CO2) released from body
tissues into the blood is present as
(1) 70% carbamino-haemoglobin and 30% as
bicarbonate
(2) Carbamino-haemoglobin in RBCs
(3) Bicarbonate in blood plasma and RBCs
(4) Free CO2 in blood plasma
Ans. (3)
Sol. 20-25% of CO2 is transported by RBCs in the form
of carbamino hemoglobin. Whereas, 70% is carried
as bicarbonate about 7% of CO2 is carried in a
dissolved state in plasma.

9. In mitochondria, protons accumulate in the
(1) Intermembrane space
(2) Matrix
(3) Outer membrane
(4) Inner membrane
Ans. (1)
Sol. Protons from complex I, III and IV of respiratory e–
transport moves to PMS, creating proton gradient.

10. The unequivocal proof of DNA as the genetic
material came from the studies on a
(1) Viroid (2) Bacterial virus
(3) Bacterium (4) Fungus
Ans. (2)
Sol. Hershey and Chase worked with viruses that
infect bacteria (i.e., bacteriophages).

11. Whorled simple leaves with reticulate venation are
present in
(1) China Rose (2) Alstonia
(3) Calotropis (4) Neem
Ans. (2)

Sol. Neem – Compound leaf; Calotropis – opposite
phyllotaxy; China rose – alternate phyllotaxy.

12. Given below is the ECG of a normal human.
Which one of its components is correctly
interpreted below?
P Q S
R
T
(1) Peak P and Peak R together – systolic and
diastolic blood pressures
(2) Peak P – Initiation of left atrial contraction
only
(3) Complex QRS – One complete pulse
(4) Peak T – Initiation of total cardiac contraction
Ans. (3)
Sol. The P-wave represents depolarisation of atria,
which leads to the contraction of both atria.
QRS wave represents depolarisation of atria which
initiates ventricular contraction. There is one
ventricular contraction during one heart beat as
heart beat rate is equal to pulse rate, so QRS
complex represents one complete pulse.
