1. Bioenergetics Exam Framework

Essential Points

📌 Bioenergetics questions commonly test pathway location, inputs and outputs, and ATP or electron-carrier counts together.

📌 The figures 36 or 38 ATP per glucose are theoretical maximum values, whereas the realistic yield is approximately 30–32 ATP because efficiency and NADH transport costs vary.

  • Glycolysis occurs in the cytoplasm, the Krebs cycle occurs in the mitochondrial matrix, and the respiratory electron transport chain occurs across the inner mitochondrial membrane.

What do bioenergetics questions commonly test together?

Pathway location, inputs and outputs, and ATP or electron-carrier counts.

What are the theoretical maximum ATP yields per glucose?

36 or 38 ATP per glucose.

Why is the realistic ATP yield per glucose lower than theoretical values?

Because efficiency and NADH transport costs vary.

Where does glycolysis occur in the cell?

In the cytoplasm.

Where does the Krebs cycle occur?

In the mitochondrial matrix.

Where does the respiratory electron transport chain occur?

Across the inner mitochondrial membrane.
