The starting molecule for the Krebs cycle is

• glucose.
• pyruvic acid.

Cellular respiration releases energy by breaking down

• food molecules.
• ATP

Which of the following is the correct sequence of events in cellular respiration?

• glycolysis ® Krebs cycle ® electron transport
• glycolysis ® fermentation ® Krebs cycle
• Krebs cycle ® electron transport ® glycolysis

How do organisms get the energy they need?

• by breathing oxygen into the lungs and combining it with carbon dioxide
• by breaking down food molecules gradually and capturing their chemical energy
• by using the sun’s energy to break down food molecules and form chemicals

What is the function of NADP+?

• It absorbs light
• It is an electron carrier
• It is a light-reflecting pigment
• It acts as long-term energy storage

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

Where does cellular respiration takes place?

• chloraplast
• nucleus
• mitochondria
