   d) NAD+

   i) The cycle that produces ATP, NADH, and FADH2.
   ii) A process that occurs in muscle cells during anaerobic conditions.
   iii) A coenzyme that carries electrons.
   iv) The stage of respiration where most ATP is produced.

Essay Question

7. Discuss the role of ATP in cellular respiration.
   • Explain how ATP is produced and its importance in cellular activities.

Application/Analysis Questions

8. What factors can affect the rate of cellular respiration in cells?

   • Discuss at least three factors that influence the rate of cellular respiration and explain how they impact the process.

9. Describe how cellular respiration differs in yeast and muscle cells.

   • Compare and contrast the types of respiration occurring in yeast during fermentation and in human muscle cells during heavy exercise.

Practical Application Question

10. Design an experiment to measure the rate of respiration in yeast using a simple setup.
    • Outline the steps you would take and the materials you would use, including how you would measure the rate of respiration.

These questions provide a varied assessment of understanding related to cellular respiration, encompassing definitions, explanations, comparisons, and practical applications.
