Cell Respiration and Cycles

The conversion of glucose to two molecules of pyruvate is the result of what process?

• the krebs cycle
• glycolysis
• the electron transport chain
• oxidative phosphorylation

The overall equation for cellular respiration is:

• C₆H₁₂O₆ + ATP -> 6CO₂ + 6H₂O + ATP
• CH₂O + O₂ -> CO₂ + 6H₂O + ATP
• C₆H₁₂O₆ + 6O₂ -> 6CO₂ + 6H₂O + ATP
• C₆H₁₂O₆ + 6CO₂ -> 6O₂ + 6H₂O + ATP
