Question 3

A patient receives an intravenous solution that is hypertonic relative to their intracellular fluid. What is the most likely effect on their red blood cells?

Question 4

Which organelle is responsible for producing most of the cell’s ATP through aerobic metabolism?

Accepted Answer

Mitochondrion

Question 5

Which of the following best describes the function of the rough endoplasmic reticulum (RER)?

Accepted Answer

Modifies and packages newly synthesized proteins for export

Question 6

A mutation in the gene encoding a lysosomal enzyme leads to accumulation of undigested substrates in cells. Which disease mechanism does this illustrate?

Accepted Answer

Lysosomal storage disorder

Question 7

Which of the following best explains why red blood cells lack mitochondria?

Accepted Answer

They rely solely on glycolysis for ATP production.

Question 8

Which of the following is a function of the glycocalyx on the plasma membrane?

Accepted Answer

Cell recognition and binding to extracellular structures

Question 9

Which process is described by the equation $$ \mathrm{C}_6\mathrm{H}_{12}\mathrm{O}_6 + 6\mathrm{O}_2 \rightarrow 6\mathrm{CO}_2 + 6\mathrm{H}_2\mathrm{O} + \mathrm{ATP} $$ and where does it primarily occur?

Accepted Answer

Aerobic respiration in mitochondria

Question 10

Which of the following best describes the role of ribosomal RNA (rRNA) during protein synthesis?

Accepted Answer

Forms the core of the ribosome and catalyzes peptide bond formation

Question 11

A cell is placed in a solution and water moves into the cell, causing it to swell. What is the tonicity of the solution relative to the cell?

Accepted Answer

Hypotonic

Question 12

Which of the following best describes the function of the sodium-potassium ATPase pump?

Accepted Answer

It moves 3 Na$$^+$$ ions out of the cell and 2 K$$^+$$ ions into the cell using ATP.

Question 13

Which of the following is a characteristic of malignant tumors but NOT benign tumors?

Accepted Answer

Cells divide rapidly and invade surrounding tissues

Question 14

Which of the following best describes the process of transcription?

Accepted Answer

Synthesis of mRNA from a DNA template

Question 15

Which of the following is true regarding the structure of DNA in the nucleus of a non-dividing cell?

Accepted Answer

DNA is loosely coiled as chromatin.

Question 16

Which of the following best explains why the plasma membrane is described as 'selectively permeable'?

Accepted Answer

It allows some substances to cross while restricting others based on size, charge, and solubility.

Question 17

Which of the following is a function of the Golgi apparatus?

Accepted Answer

Modifies and packages secretions for exocytosis

Question 18

A scientist observes a cell with abundant smooth endoplasmic reticulum (SER). Which function is this cell MOST likely specialized for?

Accepted Answer

Synthesis of steroid hormones or lipids

Question 19

Which of the following best describes the role of microfilaments in the cytoskeleton?

Accepted Answer

They provide structural support and are composed of actin.
