Question 1

Which organelle is primarily responsible for producing ATP through cellular respiration, and what is the balanced chemical equation for this process?

Accepted Answer

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

Question 2

A patient has a genetic disorder affecting the function of their lysosomes. Which cellular process would be most directly impaired?

Accepted Answer

Recycling worn out cell parts and breaking down foreign particles

Question 3

Which plasma membrane transport process moves materials from low concentration to high concentration and requires energy input from ATP?

Accepted Answer

Active transport

Question 4

During transcription, what is the correct sequence of events for synthesizing mRNA from DNA?

Accepted Answer

DNA unwinds, complementary RNA bases pair with DNA, RNA strand detaches and leaves nucleus

Question 5

Which of the following best describes the structure of the plasma membrane according to the Fluid Mosaic Model?

Accepted Answer

A phospholipid bilayer with hydrophilic heads facing outward and hydrophobic tails facing inward, interspersed with proteins and cholesterol

Question 6

A cell is observed to have many cilia on its surface. What is the most likely function of these cilia?

Accepted Answer

Moving materials across the cell surface, such as mucus in the respiratory passages

Question 7

Which tissue type is specialized for transmitting electrical impulses and coordinating body functions?

Accepted Answer

Nervous tissue

Question 8

If a cell is placed in a solution with a higher concentration of solutes than the cytoplasm, which process will occur and what is the expected result?

Accepted Answer

Osmosis; water will leave the cell causing it to shrink

Question 9

Which organelle is responsible for packaging and modifying proteins for secretion from the cell?

Accepted Answer

Golgi apparatus

Question 10

During mitosis, which phase is characterized by the alignment of chromosomes along the equator of the cell?

Accepted Answer

Metaphase

Question 11

Which of the following is NOT a function of the plasma membrane?

Accepted Answer

Synthesizing proteins for cellular use

Question 12

A mutation in the gene coding for collagen would most directly affect which tissue type?

Accepted Answer

Connective tissue

Question 13

Which of the following best describes the process of translation in protein synthesis?

Accepted Answer

Ribosomes use mRNA to assemble a polypeptide chain from amino acids

Question 14

Which type of epithelial tissue is best suited for rapid diffusion and is found lining the air sacs of the lungs?

Accepted Answer

Simple squamous epithelium

Question 15

Which organelle contains enzymes that detoxify dangerous free radicals and is abundant in liver cells?

Accepted Answer

Peroxisome

Question 16

A cell in interphase is most likely to be engaged in which activity?

Accepted Answer

Carrying out normal metabolic functions and DNA replication

Question 17

Which of the following is a correct pairing of organelle and its function?

Accepted Answer

Smooth endoplasmic reticulum: Cholesterol and lipid metabolism

Question 18

Which process is responsible for the movement of water across a selectively permeable membrane from an area of low solute concentration to high solute concentration?

Accepted Answer

Osmosis

Question 19

Which of the following best explains why DNA replication is necessary before cell division?

Accepted Answer

To ensure each daughter cell receives a complete set of genetic instructions

Question 20

A researcher observes a tissue sample with cells that are tall and arranged in a single layer. Which type of epithelial tissue is this?

Accepted Answer

Simple columnar epithelium
