Question 1

Which of the following best describes the difference between anabolism and catabolism in cellular metabolism?

Accepted Answer

Anabolism builds complex molecules from simpler ones, requiring energy; catabolism breaks down molecules to release energy.

Question 2

During hydrolysis, which molecule is added to break a chemical bond, and what is the general equation for this reaction?

Accepted Answer

Water; $$AB + H_2O \rightarrow A + B$$

Question 3

Which statement about enzymes is correct?

Accepted Answer

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

Question 4

What is the primary role of ATP in cellular processes?

Accepted Answer

To provide energy for cellular activities.

Question 5

Which of the following is an example of a coenzyme and its function?

Accepted Answer

NAD+; transfers electrons during cellular respiration.

Question 6

During aerobic respiration, which molecule acts as the final electron acceptor?

Accepted Answer

Oxygen ($$O_2)$$

Question 7

Which equation correctly represents the overall process of cellular respiration?

Accepted Answer

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

Question 8

Which statement best describes the difference between aerobic and anaerobic respiration?

Accepted Answer

Aerobic respiration produces more ATP than anaerobic respiration.

Question 9

What is the function of NAD+ and FAD in energy transfer during cellular respiration?

Accepted Answer

They transfer electrons to the electron transport chain.

Question 10

Which process involves the synthesis of a new strand of DNA from an existing template?

Accepted Answer

Replication

Question 11

Which type of RNA carries amino acids to the ribosome during protein synthesis?

Accepted Answer

tRNA

Question 12

Which tissue type is characterized by tightly packed cells forming layers and is found lining body surfaces?

Accepted Answer

Question 16

Which membrane type lines body cavities that do NOT open to the outside and reduces friction between organs?

Accepted Answer

Serous membrane

Question 17

A patient is diagnosed with a genetic disorder affecting the codons in their DNA. Which process is most directly impacted?

Accepted Answer

Translation

Question 18

Which of the following best describes the function of mucous membranes?

Accepted Answer

They line cavities and tubes that open to the outside of the body.

Question 19

Which tissue type is responsible for rapid communication and control in the body?

Accepted Answer

Nervous tissue

Question 20

A marathon runner relies on which process to generate the majority of their ATP during the race?

Accepted Answer

Aerobic respiration
