What is the net yield of ATP per glucose molecule in the Krebs Cycle?

• 6 ATP

• 4 ATP

• 2 ATP

• 0 ATP

What is the electron carrier in the electron transport chain?

• ATP

• FADH2

• NADH

• GTP

What is the preparatory step of the Krebs Cycle?

• Oxidation of acetyl CoA into pyruvate

• Conversion of pyruvate into acetyl CoA

• Oxidation of pyruvate into acetyl CoA

• Conversion of acetyl CoA into pyruvate

What is the final product of glycolysis?

• Pyruvate

• Glucose

• ATP

• NADH

Which molecule is the starting substrate for the Krebs Cycle?

• Pyruvate

• Acetyl CoA

• Glucose

• Fructose 6-phosphate

This process releases chemical energy from sugars to make ATP when oxygen is present.

• photosynthesis
• light-independent reaction
• cellular respiration
• light-dependent reaction

This is referred to as the energy currency of the cell

• ADP
• ATP
• Mitochondria
• Nucleus

What is the correct equation for cellular respiration?

• 6O₂ + C₆H₁₂O₆ -> 6CO₂ + 6H₂O + Energy
