  • 2. 

    At the end of cellular respiration, a cell can yield a net total of 38 ATP molecules per glucose molecule.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    Did you get the answer incorrect? Hint - Glycolysis is a step that consumes and produces ATP whilst the remaining two steps produce ATP. Was this considered in your calculation?

    Rate this question:

  • 3. 

    Which isn't an end product of glycolysis?

    • 2 Carbon Dioxide Molecules

    • 2 ATP

    • 2 Pyruvate Molecules

    • 2 NADH

    Correct Answer
    A. 2 Carbon Dioxide Molecules
    Explanation
    Did you get the answer incorrect? Hint - The picture below shows an overview of Glycolysis. Also refer to the 'Glycolysis' page on the website.

    Rate this question:

  • 4. 

    What is the basic chemical formula for cellular respiration?

    • C6H12O6 + 6O2 → 6CO2 + 6H2O + ATP

    • C6H12O6 + 6CO2 → 6H2O + 6O2 + ATP

    • 6H2O + 6O2 + ATP → 6CO2 + C6H12O6

    Correct Answer
    A. C6H12O6 + 6O2 → 6CO2 + 6H2O + ATP
    Explanation
    Did you get the answer incorrect? Hint - Cellular respiration refers to what cells do to break up sugars. Also refer to the 'Cellular Respiration' page on the website.

    Rate this question:

  • 5. 

    Which of the following metabolic processes generates the most ATP?

    • Oxidative Phosphorylation

    • Glycolysis

    • Tricarboxylic Acid Cycle

    • Oxidation

    • Reduction

    Correct Answer
    A. Oxidative Phosphorylation
    Explanation
    Did you get the answer incorrect? Hint - What are the three metabolic processes in cellular respiration and of these which ones consume, produce ATP.

    Rate this question:

  • 6. 

    The tricarboxylic acid cycle occurs within the mitochondria of a cell. Which best describes the site of the tricarboxylic acid cycle inside the mitochondria?

    • Outer Mitochondrial Membrane

    • Inner Mitochondrial Membrane

    • Mitochondrial Matrix

    Correct Answer
    A. Mitochondrial Matrix
    Explanation
    Did you get the answer incorrect? Hint - Look at the picture below. Also refer to the 'Tricarboxylic Acid Cycle' page of the website.

    Rate this question:

  • 7. 

    Most ATP produced by oxidative phosphorylation is generated from the oxidation of NADH and ____________.

    Correct Answer
    FADH2
    Explanation
    Most ATP produced by oxidative phosphorylation is generated from the oxidation of NADH and FADH2. During oxidative phosphorylation, electrons from NADH and FADH2 are transferred through the electron transport chain, which generates a proton gradient across the inner mitochondrial membrane. This proton gradient is then used by ATP synthase to produce ATP. NADH and FADH2 are both electron carriers that donate electrons to the electron transport chain, but NADH generates more ATP than FADH2 because it enters the electron transport chain at an earlier stage, resulting in more proton pumping and ATP synthesis.

    Rate this question:

  • 8. 

    Upon entering the mitochondria, pyruvate is converted to _____________ to be used in the tricarboxylic acid cycle.

    Correct Answer
    acetyl coenzyme A
    acetyl CoA
    Acetyl CoA
    Explanation
    Did you get the answer incorrect? Hint - Refer to the 'Tricarboxylic Acid Cycle' page on the website.

    Rate this question:

  • 9. 

    What are the three main stages of cellular respiration?

    • Glycolysis, Oxidation and Tricarboxylic Acid Cycle.

    • Cellular Respiration, Oxidation and Reduction.

    • Glycolysis, Tricarboxylic Acid Cycle and Oxidative Phosphorylation.

    • Glycolysis, the Krebs Cycle, and Electron Transport Chain.

    Correct Answer(s)
    A. Glycolysis, Tricarboxylic Acid Cycle and Oxidative Phosphorylation.
    A. Glycolysis, the Krebs Cycle, and Electron Transport Chain.
    Explanation
    Did you get the answer incorrect? Hint - The first stage of cellular respiration sees the breakdown of glucose, the second stage sees pyruvic acid and NADH used to make ATP and stage 3 sees NADH and FADH2 oxidised forming an H+ electron. Also refer to the 'Cellular Respiration' page on the website.
