Q: Which equation best represents aerobic cellular respiration in animal cells?

$$\text{C}_6\text{H}_{12}\text{O}_6 + 6\text{O}_2 \rightarrow 6\text{CO}_2 + 6\text{H}_2\text{O} + \text{ATP}$$

Q: Which of the following is NOT a product of photosynthesis?

Carbon dioxide ($$\text{CO}_2)$$

Question 1

Which of the following best describes the function of the cell membrane in biological transport?

Accepted Answer

It selectively allows certain molecules to pass while blocking others, maintaining homeostasis.

Question 2

A student places a plant cell in a solution with a higher solute concentration than the cell's cytoplasm. What is most likely to happen to the cell?

Accepted Answer

The cell will lose water and the cytoplasm will shrink away from the cell wall, a process called plasmolysis.

Question 3

Which factor would most likely increase the rate of diffusion across a cell membrane?

Accepted Answer

Increasing the temperature of the environment.

Question 4

Which equation best represents aerobic cellular respiration in animal cells?

Accepted Answer

$$	ext{C}_6	ext{H}_{12}	ext{O}_6 + 6	ext{O}_2 ightarrow 6	ext{CO}_2 + 6	ext{H}_2	ext{O} + 	ext{ATP}$$

Question 5

Which of the following is NOT a product of photosynthesis?

Accepted Answer

Carbon dioxide ($$	ext{CO}_2)$$

Question 6

Which pigment is primarily responsible for absorbing light energy during photosynthesis in plants?

Accepted Answer

Chlorophyll a

Question 7

A yeast cell is placed in an anaerobic environment. Which product is most likely to be produced during cellular respiration?

Accepted Answer

Ethanol

Question 8

Which of the following best describes the role of guard cells in plant leaves?

Accepted Answer

They regulate the opening and closing of stomata to control gas exchange.

Question 9

Which stage of mitosis is characterized by the alignment of chromosomes along the center of the cell?

Accepted Answer

Metaphase

Question 10

A student observes animal cells placed in a hypotonic solution. What is the most likely outcome?

Accepted Answer

The cells will burst due to excessive water intake.

Question 11

Which of the following best describes the effect of pH on enzyme activity?

Accepted Answer

Each enzyme has an optimal pH, and activity decreases above or below this value.

Question 12

Which of the following is a major difference between aerobic and anaerobic cellular respiration?

Accepted Answer

Aerobic respiration produces more ATP than anaerobic respiration.

Question 13

Which structure in plant leaves is directly involved in gas exchange?

Accepted Answer

Stomata

Question 14

A molecule with a large size and a strong negative charge is less likely to diffuse across a cell membrane. Which principle explains this observation?

Accepted Answer

Diffusion rate decreases with increasing molecule size and charge.

Question 15

Which of the following is a reactant in the photosynthesis equation?

Accepted Answer

Carbon dioxide ($$	ext{CO}_2)$$

Question 16

During which phase of the cell cycle does DNA replication occur?

Accepted Answer

Interphase

Question 17

A student measures the rate of diffusion of a dye in water at two different temperatures. At 25°C, the dye diffuses at a rate of $$2 	ext{cm}^2/	ext{min}$$, and at 35°C, it diffuses at $$4 	ext{cm}^2/	ext{min}. $$Which factor is most responsible for this change?

Accepted Answer

The temperature increased, causing molecules to move faster.

Question 18

Which of the following best explains why plant cells do not burst when placed in a hypotonic solution?

Accepted Answer

Plant cells have a rigid cell wall that prevents bursting.
