Question 1

Which organelle is primarily responsible for packaging proteins for export from the cell or insertion into the plasma membrane?

Accepted Answer

Golgi Apparatus

Question 2

During which phase of the cell cycle is DNA visible as chromatin and the nuclear envelope and nucleoli are intact?

Accepted Answer

Interphase

Question 3

A patient’s liver cells are found to have an abnormally high number of peroxisomes. What is the most likely physiological reason for this?

Accepted Answer

Detoxification of alcohol and other harmful chemicals

Question 4

Which of the following best describes the plasma membrane’s function in maintaining cellular homeostasis?

Accepted Answer

It is selectively permeable, allowing only certain substances to enter or leave the cell.

Question 5

If a cell’s lysosomes rupture, what is the most likely outcome?

Accepted Answer

The cell will be destroyed due to the release of digestive enzymes.

Question 6

Which organelle is the site of steroid and lipid synthesis, as well as drug detoxification?

Accepted Answer

Smooth Endoplasmic Reticulum

Question 7

What is the primary function of ribosomes in the cell?

Accepted Answer

Protein synthesis

Question 8

Which cytoskeletal element is primarily responsible for providing the cell’s shape?

Accepted Answer

Microtubules

Question 9

A cell is observed to have a folded plasma membrane. What is the most likely reason for this structural adaptation?

Accepted Answer

To increase surface area for absorption or exchange

Question 10

Which of the following equations best represents the process of ATP production in mitochondria?

Accepted Answer

$$\mathrm{C_6H_{12}O_6$} + 6\mathrm{O_2$} \rightarrow 6\mathrm{CO_2$} + 6\mathrm{H_2O} + \mathrm{ATP}$$

Question 11

During mitosis, which structure is directly responsible for organizing and forming the mitotic spindle?

Accepted Answer

Centrioles

Question 12

Which phase of mitosis is characterized by the alignment of chromosomes along the center of the cell?

Accepted Answer

Metaphase

Question 13

A cell is observed to have its chromosomes condensed and the nuclear envelope disintegrating. Which phase of mitosis is this cell most likely in?

Accepted Answer

Prophase

Question 14

Which of the following is NOT a function that cells must carry out to maintain life?

Accepted Answer

Produce hormones for the entire organism

Question 15

Which organelle contains genetic material and is necessary for all reproduction?

Accepted Answer

Nucleus

Question 16

Which of the following best explains why the nuclear envelope is described as 'very porous'?

Accepted Answer

It allows RNA and proteins to readily exit the nucleus.

Question 17

Which organelle is most likely to be abundant in cells that are actively synthesizing proteins for export?

Accepted Answer

Rough Endoplasmic Reticulum

Question 18

Which of the following statements about mitosis is correct?

Accepted Answer

It results in two genetically identical daughter cells.

Question 19

A cell is observed to have a large number of mitochondria. What is the most likely function of this cell?

Accepted Answer

High energy production for active processes

Question 20

Which of the following best describes the difference between mitosis and meiosis?

Accepted Answer

Mitosis produces two identical daughter cells, while meiosis produces four non-identical daughter cells.
