Q: Which equation correctly represents the process of aerobic cellular respiration in mitochondria?

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

Question 1

Which statement best describes the difference between prokaryotic and eukaryotic cells?

Accepted Answer

Eukaryotic cells have a nucleus and membrane-bound organelles, while prokaryotic cells do not.

Question 2

According to the Cell Theory, which of the following is NOT a tenet?

Accepted Answer

Cells are the basic unit of structure and function in living things.

Question 3

A scientist observes a cell with a nucleoid region, ribosomes, and a plasma membrane, but no membrane-bound organelles. What type of cell is this most likely to be?

Accepted Answer

Prokaryotic cell

Question 4

Which organelle is primarily responsible for synthesizing proteins that are exported from the cell?

Accepted Answer

Rough Endoplasmic Reticulum

Question 5

A mutation causes a cell to lose its ability to produce turgor pressure. Which structure is most likely affected?

Accepted Answer

Central Vacuole

Question 6

Which of the following best explains why phospholipids form bilayers in water?

Accepted Answer

Phospholipids have hydrophilic heads and hydrophobic tails, causing them to arrange with heads facing water and tails away from water.

Question 7

Which equation correctly represents the process of aerobic cellular respiration in mitochondria?

Accepted Answer

$C_6H_{12}O_6 + 6\ O_2 ightarrow 6\ CO_2 + 6\ H_2O + 	ext{ATP}$

Question 8

A cell is observed to have many chloroplasts, a large central vacuole, and a cell wall. Which type of cell is this?

Accepted Answer

Plant cell

Question 9

Which organelle is responsible for modifying, sorting, and packaging proteins for secretion?

Accepted Answer

Golgi Apparatus

Question 10

Which cytoskeletal element is primarily responsible for cell movement and is made of actin?

Accepted Answer

Microfilaments

Question 11

A cell is unable to degrade and recycle old organelles and proteins. Which organelle is most likely malfunctioning?

Accepted Answer

Lysosome

Question 12

Which of the following is a function of the extracellular matrix in animal cells?

Accepted Answer

Providing structural support and anchoring cells

Question 13

Which process describes the movement of water across a cell membrane from an area of low solute concentration to high solute concentration?

Accepted Answer

Osmosis

Question 14

Which organelle is the site of ribosome synthesis in eukaryotic cells?

Accepted Answer

Nucleolus

Question 15

Which of the following best describes the Endosymbiont Theory?

Accepted Answer

Mitochondria and chloroplasts originated as free-living prokaryotes engulfed by ancestral eukaryotic cells.

Question 16

Which structure is responsible for the movement of chromosomes during cell division?

Accepted Answer

Centrosome

Question 17

Which of the following is NOT a function of the cytoskeleton?

Accepted Answer

Synthesizing proteins

Question 18

Which of the following best describes the role of ribosomes in the cell?

Accepted Answer

Ribosomes are the site of protein synthesis.

Question 19

A cell is observed to have cilia on its surface. What is the primary function of these structures?

Accepted Answer

Motility and movement of substances across the cell surface

Question 20

Which of the following is true about the plasma membrane?

Accepted Answer

It is selectively permeable, allowing only certain substances to pass through.
