Cellular Respiration Unit Plan (11 days)

Assessment Statements:

Glycolysis

3.7.2

State that, in cell respiration, glucose in the cytoplasm is broken down by glycolysis into pyruvate, with a small yield of ATP.

 

8.1.2

Outline the process of glycolysis, including phosphorylation, lysis, oxidation and ATP formation.

 

 

Aerobic Respiration

3.7.1

Define cell respiration.

 

3.7.4

Explain that, during aerobic cell respiration, pyruvate can be broken down in the mitochondrion into carbon dioxide and water with a large yield of ATP.

 

8.1.1

State that oxidation involves the loss of electrons from an element, whereas reduction involves a gain of electrons; and that oxidation frequently involves gaining oxygen or losing hydrogen, whereas reduction frequently involves losing oxygen or gaining hydrogen.

 

8.1.3

Draw and label a diagram showing the structure of a mitochondrion as seen in electron micrographs.

 

8.1.4

Explain aerobic respiration, including the link reaction, the Krebs cycle, the role of NADH + H+, the electron transport chain and the role of oxygen.

 

8.1.5

Explain oxidative phosphorylation in terms of chemiosmosis.

 

8.1.6

Explain the relationship between the structure of the mitochondrion and its function.

 

 

Fermentation

3.7.3

Explain that, during anaerobic cell respiration, pyruvate can be converted in the cytoplasm into lactate, or ethanol and carbon dioxide, with no further yield of ATP.

What You Need to Know

  1. Explain the purpose served by molecules of ATP reacting first with glucose and then with fructose-6-phosphate in the early part of glycolysis. 

  2. Explain how four ATP molecules are made for every two used during glycolysis.

  3. State the events that happen during acetyl-coenzyme A formation and explain how the process of acetyl-CoA formation relates to glycolysis and the Krebs Cycle.

  4. State what happens to the CO2 produced during acetyl-CoA formation and the Krebs Cycle.

  5. Explain what happens to the NADH produced during acetyl-CoA formation and the Krebs Cycle.

  6. Calculate the number of ATP moleculesproduced during the Krebs cycle for each glucose molecule that enters gylcolysis.

  7. Summarize the basic ideas of the chemiosmotic theory.

  8. Describe the process of electron transport phosphorylation.

  9. Account for the next yield of 36 ATP molecules produced through aerobic respiration.
