Accepted Answer

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

Question 3

A scientist observes a cell with a cell wall, chloroplasts, and a large central vacuole. Which type of cell is most likely being observed?

Accepted Answer

Plant cell

Question 4

Which of the following statements about enzymes is correct?

Accepted Answer

Enzymes lower the activation energy required for a reaction to occur.

Question 5

Which of the following best explains why ATP is important for cellular function?

Accepted Answer

ATP provides energy for cellular processes by releasing a phosphate group.

Question 6

A cell is placed in a solution and swells until it bursts. What type of solution was the cell placed in?

Accepted Answer

Hypotonic

Question 7

Which of the following is a correct description of facilitated diffusion?

Accepted Answer

Movement of molecules through a membrane via transport proteins, without energy input.

Question 8

Which organelle is primarily responsible for producing ATP in eukaryotic cells?

Accepted Answer

Mitochondrion

Question 9

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

Accepted Answer

Metaphase

Question 10

Which of the following best describes the 'fluid mosaic model' of the cell membrane?

Accepted Answer

A flexible bilayer of phospholipids with proteins and other molecules embedded throughout.

Question 11

Which process is responsible for the movement of water across a selectively permeable membrane?

Accepted Answer

Osmosis

Question 12

Which of the following is NOT a function of the extracellular matrix in animal cells?

Accepted Answer

Storing genetic information

Question 13

Which of the following best describes the difference between active and passive transport?

Accepted Answer

Active transport requires energy and moves substances against their concentration gradient, while passive transport does not require energy and moves substances down their concentration gradient.

Question 14

Which of the following is a correct equation for cellular respiration?

Accepted Answer

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

Question 15

A patient is diagnosed with a genetic disorder that affects the lysosomes in their cells. Which cellular process is most likely impaired?

Accepted Answer

Digestion of cellular waste and macromolecules

Question 16

Which of the following best explains why chemotherapy can result in hair loss?

Accepted Answer

Chemotherapy targets rapidly dividing cells, including hair follicle cells.

Question 17

Which of the following is a function of glycoproteins in the cell membrane?

Accepted Answer

Cell recognition and signaling

Question 18

Which of the following best describes the role of cholesterol in the cell membrane?

Accepted Answer

Cholesterol increases membrane fluidity at low temperatures and decreases it at high temperatures.

Question 19

Which of the following statements about meiosis is correct?

Accepted Answer

Meiosis results in gametes with half the chromosome number of the parent cell.

Question 20

Which of the following best explains the difference between hypothesis-based science and discovery science?

Accepted Answer

Discovery science involves making observations and collecting data, while hypothesis-based science involves testing predictions through experiments.
