Accepted Answer

$$C_6H_{12}O_6$ + 6 	ext{O}_2 ightarrow 6 	ext{CO}_2 + 6 	ext{H}_2	ext{O} + 	ext{ATP}$$

Question 2

During which stage of cellular respiration is the majority of ATP produced?

Accepted Answer

Electron Transport Chain

Question 3

Which of the following is the main purpose of photosynthesis?

Accepted Answer

To convert solar energy into chemical energy stored in glucose

Question 4

In the electron transport chain, what is the final electron acceptor?

Accepted Answer

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

Question 5

Which of the following best describes the role of ATP synthase in cellular respiration?

Accepted Answer

It uses the energy from a proton gradient to synthesize ATP from ADP and phosphate

Question 6

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

Accepted Answer

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

Question 7

What is the main function of the Calvin Cycle in photosynthesis?

Accepted Answer

To convert carbon dioxide into glucose

Question 8

Which structure in the mitochondrion is the site of the electron transport chain?

Accepted Answer

Inner mitochondrial membrane

Question 9

Which of the following best explains why fermentation is less efficient than aerobic respiration?

Accepted Answer

Fermentation only includes glycolysis, which produces 2 ATP per glucose

Question 10

Which pigment is primarily responsible for the green color of plants and is essential for photosynthesis?

Accepted Answer

Chlorophyll

Question 11

What is the correct complementary mRNA sequence for the DNA template strand T A C C G T A?

Accepted Answer

A U G G C A U

Question 12

Which of the following best describes the semiconservative nature of DNA replication?

Accepted Answer

Each new DNA molecule consists of one old (parental) strand and one new strand

Question 13

During transcription, what is the role of RNA polymerase?

Accepted Answer

It unwinds the DNA and synthesizes a complementary RNA strand

Question 14

Which of the following is NOT a component of a nucleotide?

Accepted Answer

Amino acid

Question 15

What is the function of tRNA during translation?

Accepted Answer

It carries amino acids to the ribosome and matches them to the mRNA codon

Question 16

Which of the following best describes a missense mutation?

Accepted Answer

A mutation that changes one amino acid to another in the protein

Question 17

Which of the following is a real-life example of an autotroph?

Accepted Answer

A maple tree

Question 18

Which of the following best explains why oxygen is required for aerobic cellular respiration?

Accepted Answer

Oxygen acts as the final electron acceptor in the electron transport chain

Question 19

Which of the following statements about the genetic code is correct?

Accepted Answer

It is universal and shows mRNA codons that specify amino acids

Question 20

A mutation that inserts or deletes a nucleotide in a gene is called a:

Accepted Answer

Frameshift mutation
