The first stage of cellular respiration is glycolysis, which literally means 'sugar splitting.' When glucose, a 6-carbon sugar, is broken down during glycolysis, what product forms?

• 2 molecules of lactic acid, C3H6O3

• 3 molecules of ethanol, C2H5OH

• 2 molecules of pyruvic acid, C3H4O3

• 6 molecules of carbon dioxide, CO2

How do high-energy electrons from glycolysis and the Krebs cycle contribute to the formation of ATP from ADP in the electron transport chain?

• a. High-energy electrons interact with pyruvic acid to create a phosphate bond with ADP, forming ATP.

• b. High-energy electrons pass through the electron transport chain to supply the needed energy to synthesize ATP from ADP.

• c. High-energy electrons supply a negative charge which causes the citric acid to oxidize, forming a phosphate group to bond with ADP.

• d. High-energy electrons increase the temperature of ADP so it readily reacts with a phosphate group to form ATP.

What is the correct equation for cellular respiration?

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

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

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