Cellular Respiration

True or False: Electron carriers are found in the inner mitochondrial membrane

• True
• False

Which of the following is not an end product of the Kreb's cycle?

• FADH₂
• CO₂
• pyruvate
• ATP

What process is found in both aerobic and anaerobic metabolism?

• the Kreb's cycle
• oxidative phosphorylation
• the citric acid cycle
• glycolysis

What are the byproducts of cellular respiration?

• NADH and ATP
• oxygen and heat
• FADH2 and NADH
• CO₂ and H₂O

The overall equation for cellular respiration is:

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

During cellular respiration the energy in glucose

• is carried by electrons
• is used to manufacture glucose
• becomes stored in molecules of water
• is released all at one

Which process produces the most ATP per molecule of glucose?

• lactic acid fermentation
• aerobic respiration
• alcoholic fermentation
• all are about the same

What does NADH do during cellular respiration?

•  it delivers its electron load to the first electron carrier molecule
• it is reduced to form NAD+
• it is chemically converted into ATP
• it acts as the final electron acceptor

What process occurs when sugar is converted into ENERGY (ATP)

• Photosynthesis
• Cellular Respiration

Which step of cellular respiration makes the most ATP?

• Glycolysis
• Krebs Cycle
• Electron Transport Chain
• Light Dependent Reactions
