Cell Respiration

Question 1

Explain how breathing and cellular respiration are related.

Answer 1

In Breathing, CO2 & O2 are exchanged between your lungs and the air. In Cellular Respiration cells use the O2 obtained through the breathing to breakdown fuel, releasing CO2 as a waste product.

Question 2

Provide the overall balanced chemical equation for cellular respiration.

Answer 2

C6H12O6 + 6O2 → 6CO2 + 6H2O.

Question 3

Explain how the energy in a glucose molecule is released during cellular
respiration.

Answer 3

During cellular respiration, glucose is broken down in the presence of oxygen to produce carbon dioxide and water. Energy released during the reaction is captured by the energy-carrying molecule ATP (adenosine triphosphate).
