Aerobic Respiration Trivia Quiz - Quiz

This quiz contains questions relating to cellular respiration. It specifically focuses on aerobic respiration and the biological mechanisms that go into producing energy that living things use to function. The content for this quiz can be found in the Princeton Review book from pages 57 - 62.


Questions and Answers
  • 1. 

    In order to produce a molecule of Adenosine Triphosphate, oxygen must be present.

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    Adenosine Triphosphate (ATP) is a product of cellular respiration. There are two forms of respiration; aerobic (when oxygen is present) and anaerobic (when oxygen is not present).
    AER (think air...air contains oxygen)
    AN (means not)...so....NOT AER means no oxygen

      Adenosine triphosphate

    • D.

      Glucose

    Correct Answer
    D. Glucose
    Explanation
    Glucose is a reactant in the chemical equation for cellular respiration.

    Rate this question:

  • 3. 

    List the four main stages of aerobic respiration: (number them in your answer) 1. 2. 3. 4.

  • 4. 

    How many carbon atoms make up 1 molecule of glucose?

    • A.

      3

    • B.

      4

    • C.

      5

    • D.

      6

    Correct Answer
    D. 6
    Explanation
    Glucose is a simple sugar with the molecular formula C6H12O6. This means that each molecule of glucose contains 6 carbon atoms. Therefore, the correct answer is 6.

  • 5. 

    The book uses the expression "you have to spend money to earn money" in regards to ATP production during glycolysis.  Describe how glycolysis "spends" in order to "make".

  • 6. 

    Which of the following regarding glycolysis are true:

    • A.

      It occurs in the matrix of the mitochondria

    • B.

      It occurs in the cytoplasm of the cell

    • C.

      It does not happen inside of the mitochondria

    • D.

      4 net ATP's are produced

    • E.

      4 ATP's are produced

    • F.

      Glucose is broken down into two 3 carbon sugars

    • G.

      Glucose is broken down into three 2 carbon sugars

    • H.

      2 NADH molecules are produced

    Correct Answer(s)
    B. It occurs in the cytoplasm of the cell
    C. It does not happen inside of the mitochondria
    E. 4 ATP's are produced
    F. Glucose is broken down into two 3 carbon sugars
    H. 2 NADH molecules are produced
    Explanation
    Glycolysis is a metabolic pathway that occurs in the cytoplasm of the cell, not in the matrix of the mitochondria. It is the first step in cellular respiration and breaks down glucose into two 3 carbon sugars called pyruvate. During glycolysis, 4 ATP molecules are produced, but 2 ATP molecules are used in the process, resulting in a net production of 2 ATPs. Additionally, 2 NADH molecules are produced as a result of glycolysis.

    Rate this question:

  • 7. 

    Glycolysis is an anaerobic process

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    Glycolysis is indeed an anaerobic process. It is the first step in cellular respiration, where glucose is broken down into pyruvate molecules. This process occurs in the cytoplasm of cells and does not require oxygen. In the absence of oxygen, pyruvate can then undergo fermentation to produce energy in the form of ATP. Therefore, it is correct to say that glycolysis is an anaerobic process.

    Rate this question:

  • 8. 

    When oxygen is present, a pyruate (pyruvic acid) enters the second stage of aerobic respiration, which is the formation of Acetyl coenzyme A.  Which of the following is true about that process?

    • A.

      Carbon dioxide is a product

    • B.

      Oxygen is a reactant

    • C.

      2 more NADH's are formed

    • D.

      Acetyl coenzyme A is a 3 carbon sugar

    • E.

      Acetyl coenzyme A is a 2 carbon sugar

    Correct Answer(s)
    A. Carbon dioxide is a product
    C. 2 more NADH's are formed
    E. Acetyl coenzyme A is a 2 carbon sugar
    Explanation
    In the second stage of aerobic respiration, pyruvate is converted into Acetyl coenzyme A. This process involves the release of carbon dioxide as a byproduct. Additionally, two more molecules of NADH are formed during this process. Acetyl coenzyme A is a molecule consisting of two carbon atoms, making it a 2 carbon sugar.

    Rate this question:

  • 9. 

    The Krebs cycle is the third step of cellular respiration.  it is also known as the citric acid cycle because as soon as acetyle coenzyme A enters the cycle it undergoes a chemical reaction that creates a citric acid molecule which then moves on to the next stage of reactions. Citric Acid contains 6 carbon molecules.  EXPLAIN how the 2 carbon sugar gets turned into a 6 carbon sugar again.

  • 10. 

    The kreb cycle is where most of the ATP in aerobic respiration is formed?

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    only 1 ATP IS FORMED

    Rate this question:

  • 11. 

    So if you only make 2 ATP per glucose molecule (1 for each turn - remember that  for each turn you are only using half of the glucose) what is the point of the kreb cycle????

  • 12. 

    Look at figure 1 on page 59:  Where are the proteins that make up the electron transport chain located?

    • A.

      Inner membrane

    • B.

      Outer membrane

    • C.

      Matrix

    • D.

      Intermembrane space

    Correct Answer
    A. Inner membrane
    Explanation
    The proteins that make up the electron transport chain are located in the inner membrane. This is because the inner membrane of the mitochondria is where the majority of cellular respiration takes place, including the electron transport chain. The inner membrane is highly folded, forming structures called cristae, which provide a large surface area for the proteins involved in the electron transport chain to carry out their functions.

    Rate this question:

  • 13. 

    Oxygen plays a vital role in the electron transport chain because it is the ___________________  electron acceptor.

    Correct Answer
    final
    Explanation
    Oxygen plays a vital role in the electron transport chain because it is the final electron acceptor. In the electron transport chain, electrons are passed along a series of protein complexes and coenzymes, releasing energy. This energy is used to pump protons across the inner mitochondrial membrane, creating a proton gradient. Oxygen is the final acceptor of these electrons, combining with protons to form water. This process is essential for the production of ATP, the main energy currency of cells. Without oxygen as the final electron acceptor, the electron transport chain would be unable to continue, leading to a halt in ATP production.
