BMST - Basic Math and Science Cellular Processes and Organelles Questions and Answers

Question 1

Which organelle is correctly matched with its primary function in a eukaryotic cell?

Accepted Answer

Mitochondrion - Energy production through cellular respiration

Answer

Ribosome - Lipid synthesis and detoxification

Answer

Golgi apparatus - Storage of genetic material

Answer

Lysosome - Synthesis of proteins

Question 2

A scientist observes a cell transporting a large molecule from an area of low concentration to an area of high concentration across the cell membrane. Which cellular process is being observed, and what is its key requirement?

Accepted Answer

Active Transport - Requires energy in the form of ATP

Answer

Osmosis - Requires a semipermeable membrane

Answer

Facilitated Diffusion - Requires a carrier protein

Answer

Simple Diffusion - Requires a concentration gradient

Question 3

A red blood cell is placed in a beaker of pure, distilled water. What is the most likely outcome for the cell?

Accepted Answer

The cell will swell and likely burst (lyse) because water will move into it.

Answer

The cell will shrink (crenate) because water will move out of it.

Answer

The cell will remain unchanged because the solutions are isotonic.

Answer

The cell will undergo plasmolysis.

Question 4

Which of the following correctly describes the function of the nucleus within a eukaryotic cell?

Accepted Answer

It contains the cell's genetic material and controls cell activities.

Answer

It is the primary site of ATP synthesis.

Answer

It packages and modifies proteins for secretion.

Answer

It synthesizes lipids and detoxifies harmful substances.

Question 5

The process of cellular respiration involves several stages. In which location does the Krebs cycle (citric acid cycle) take place?

Accepted Answer

In the matrix of the mitochondria

Answer

In the cytoplasm

Answer

On the inner membrane of the mitochondria

Answer

Within the stroma of the chloroplast

Question 6

A cell needs to produce a protein that will be exported and used outside the cell. Which organelle is primarily responsible for synthesizing this protein?

Accepted Answer

Ribosomes bound to the rough endoplasmic reticulum

Answer

Free ribosomes in the cytoplasm

Answer

The smooth endoplasmic reticulum

Answer

The nucleolus
