Honors Cellular Respiration Notes

Multiple Choice

Why is cellular respiration significant for living organisms?

• It helps organisms break down glucose and create ATP, which is essential for energy.

• It allows organisms to breathe oxygen directly into their cells.

• It enables organisms to store glucose without using energy.

• It helps organisms produce carbon dioxide as a waste product.

How does cellular respiration compare to photosynthesis?

Multiple Choice

Which of the following statements best describes the relationship between photosynthesis and cellular respiration?

• Photosynthesis produces glucose and oxygen, which are used in cellular respiration to produce energy.

• Cellular respiration produces glucose and oxygen, which are used in photosynthesis to produce energy.

• Photosynthesis and cellular respiration occur in the same organelle.

• Photosynthesis and cellular respiration do not share any products or reactants.
