Class Examination Report: Cellular Respiration
Executive Summary
Overall, the class shows strong performance on foundational concepts like Glycolysis and the role of ATP Synthase. However, there is a clear knowledge gap regarding the specifics of the Krebs Cycle, particularly its role in generating electron carriers versus direct ATP. Many students also struggled to differentiate the inputs and outputs of the Electron Transport Chain. Future instruction should focus on reinforcing the sequence and specific purpose of the middle stages of respiration.

Section 2: Glycolysis
Section 3: The Krebs Cycle
Section 4: Electron Transport Chain
Section 5: ATP Synthase
Q: What is the primary function of Glycolysis?
ALICE'S ANSWER
To break down glucose into two pyruvate molecules in the cytoplasm.
AI FEEDBACK (10/10)
Correct. You've identified the main substrate, product, and location.
Q: Why are NADH and FADHâ‚‚ important products of the Krebs Cycle?
ALICE'S ANSWER
They are electron carriers that deliver high-energy electrons to the Electron Transport Chain to power ATP production.
AI FEEDBACK (10/10)
Excellent. This shows a clear understanding of their role as intermediaries.
Q: Where in the cell does the Electron Transport Chain reside?
BOB'S ANSWER
It is located in the inner mitochondrial membrane.
AI FEEDBACK (10/10)
Perfectly stated. The specific membrane is key.
Q: What is the primary purpose of the Krebs cycle?
BOB'S ANSWER
To make a lot of ATP for the cell.
AI FEEDBACK (3/10)
This is a common misconception. While some ATP (or GTP) is made, the main function is to produce NADH and FADHâ‚‚, the electron carriers for the final stage.
