Question 2

Which equation correctly represents the overall process of photosynthesis?

Accepted Answer

$$6 	ext{CO}_2 + 6 	ext{H}_2	ext{O} + 	ext{Energy (sun)} ightarrow 	ext{C}_6	ext{H}_{12}	ext{O}_6 + 6 	ext{O}_2$$

Question 3

Which macromolecule is primarily responsible for storing and transmitting genetic information?

Accepted Answer

Nucleic acids

Question 4

A marathon runner relies on which macromolecule for immediate energy during a race?

Accepted Answer

Carbohydrates

Question 5

Which stage of cellular respiration produces the most ATP?

Accepted Answer

Electron Transport Chain

Question 6

Which of the following statements about lipids is correct?

Accepted Answer

Lipids are not soluble in water and serve as long-term energy storage.

Question 7

During vigorous exercise, muscle cells may switch to which process to generate ATP in the absence of oxygen?

Accepted Answer

Lactic acid fermentation

Question 8

Which of the following is a correct description of a monomer and a polymer?

Accepted Answer

A monomer is a single unit; a polymer is a chain of many monomers.

Question 9

Which organelle is the site of photosynthesis in plant cells?

Accepted Answer

Chloroplast

Question 10

What is the main function of proteins in living organisms?

Accepted Answer

Transport substances, catalyze reactions, provide structure and support

Question 11

Which of the following best describes the relationship between photosynthesis and cellular respiration?

Accepted Answer

Photosynthesis stores energy in glucose, while cellular respiration releases energy from glucose.

Question 12

Which of the following is the correct sequence of events in aerobic cellular respiration?

Accepted Answer

Glycolysis → Krebs Cycle → Electron Transport Chain

Question 13

Which of the following is a product of the light-dependent reactions of photosynthesis?

Accepted Answer

Oxygen ($$	ext{O}_2)$$

Question 14

Which of the following best explains why lipids are important for insulation in animals?

Accepted Answer

Lipids are poor conductors of heat, helping to maintain body temperature.

Question 15

Which of the following is a function of nucleic acids in living organisms?

Accepted Answer

Storing and transmitting genetic information

Question 19

Which of the following best describes the main difference between aerobic respiration and fermentation?

Accepted Answer

Aerobic respiration requires oxygen and produces more ATP than fermentation.

Question 20

Which of the following is a real-life example of lactic acid fermentation?
