Accepted Answer

Absorption and secretion

Question 4

Which of the following best explains the role of cholesterol in the plasma membrane?

Accepted Answer

It increases membrane stability by modulating fluidity.

Question 5

A mutation causes a cell to lack peripheral proteins. Which of the following cellular processes would be MOST directly affected?

Accepted Answer

Cell shape changes during division and muscle contraction

Question 6

Which of the following equations best represents the relationship between the surface area (A) and volume (V) of a spherical cell as its radius (r) increases?

Accepted Answer

$A = 4 \pi r^2$, $V = \frac{4}{3} \pi r^3$

Question 7

Which of the following historical figures is correctly matched with their contribution to anatomy or physiology?

Accepted Answer

Robert Hooke – Developed the compound microscope and discovered the 'cell'.

Question 8

A cell is placed in a solution and begins to swell. Which type of membrane transport is most likely responsible for this observation?

Accepted Answer

Osmosis of water into the cell

Question 9

Which of the following best describes the function of integral membrane proteins?

Accepted Answer

They span the membrane and can function as channels, carriers, enzymes, or receptors.

Question 10

During the Renaissance, which factor MOST contributed to the advancement of anatomical knowledge in Europe?

Accepted Answer

Rediscovery of ancient texts in Arabic libraries and monasteries

Question 11

A patient has a genetic disorder affecting the cytoskeleton. Which of the following cellular functions is MOST likely to be impaired?

Accepted Answer

Maintenance of cell shape and intracellular transport

Question 12

Which of the following statements about the plasma membrane is CORRECT?

Accepted Answer

The plasma membrane is a dynamic fluid mosaic composed of lipids and proteins.

Question 13

Which of the following best describes the function of the glycocalyx on the plasma membrane?

Accepted Answer

It serves as a protective, carbohydrate-rich layer involved in cell recognition.

Question 14

A researcher observes that a certain cell type has a high concentration of inclusions such as glycogen granules. What is the MOST likely function of this cell?

Accepted Answer

Energy storage

Question 15

Which of the following is a direct implication of the cell theory for modern medicine?

Accepted Answer

Diseases can be treated by targeting specific cellular processes.

Question 16

Which of the following best explains why the cytoplasm is important for maintaining cell shape?

Accepted Answer

Its hydrostatic properties prevent compression, helping the cell maintain its shape.

Question 17

Which of the following best describes the difference between active and passive transport across the plasma membrane?

Accepted Answer

Active transport requires energy input, while passive transport does not.

Question 18

Which of the following scientists is credited with the first detailed anatomical drawings based on actual dissections, including the study of motion?

Accepted Answer

Leonardo da Vinci

Question 19

Which of the following best describes the function of glycolipids in the plasma membrane?

Accepted Answer

They are involved in cell recognition and are found on the outer membrane surface.

Question 20
