Accepted Answer

Mitochondria

Question 4

Which of the following best describes the structure of a nucleosome?

Accepted Answer

A segment of DNA wrapped around a core of histone proteins

Question 5

Which of the following is a non-membrane bound organelle?

Accepted Answer

Ribosome

Question 6

Which of the following statements about cell membranes is correct?

Accepted Answer

Cell membranes are dynamic and fluid, allowing lateral movement of lipids and proteins.

Question 7

Which of the following is the major electrogenic pump in animal cells?

Accepted Answer

Sodium-potassium pump

Question 8

Which process removes a phosphate group from ATP to release energy?

Accepted Answer

Hydrolysis

Question 9

During cellular respiration, which molecules act as electron carriers?

Accepted Answer

NADH and FADH$$_2$$

Question 10

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

Accepted Answer

Protein synthesis and modification for export or insertion into membranes

Question 11

A plant cell is placed in a hypertonic solution. What will most likely happen to the cell?

Accepted Answer

It will lose water and undergo plasmolysis.

Question 12

Which of the following is the primary location for photosynthesis in plants?

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

Accepted Answer

Chlorophyll a

Question 14

Which of the following best describes the difference between phagocytosis and autophagy?

Accepted Answer

Phagocytosis engulfs external particles, while autophagy digests internal cell components.

Question 15

Which of the following equations correctly represents the overall process of photosynthesis?

Accepted Answer

Question 17

Which of the following is a defining feature of life regarding metabolism?

Accepted Answer

The ability to carry out enzyme-catalyzed metabolic reactions.

Question 18

Which of the following best describes the difference between catabolic and anabolic pathways?

Accepted Answer

Catabolic pathways break down complex molecules to release energy, while anabolic pathways build complex molecules using energy.

Question 19

In the context of photosynthesis, what is the final product of the Calvin Cycle, and how many of these molecules are needed to make one glucose molecule?

Accepted Answer
