Question

The diagram below shows the relationship between photosynthesis, cellular respiration as well as the organelles in which they occur.


Which statement describes how photosynthesis and cellular respiration are interrelated?

• A. Oxygen is produced during cellular respiration and stored during photosynthesis
• B. Carbon dioxide and water released by cellular respiration are used in photosynthesis
• C. Photosynthesis releases the energy that is stored during the process of cellular respiration
• D. Glucose is used during cellular respiration to produce food that is broken down during photosynthesis

Answer 1

The correct option is B Carbon dioxide and water released by cellular respiration are used in photosynthesis

Carbon dioxide and water released by cellular respiration are used in photosynthesis. Oxygen is produced during photosynthesis and while cellular respiration (aerobic) uses oxygen. Cellular respiration releases the energy in the form of ATP whereas photosynthesis stores energy from sunlight into chemical energy (glucose). Glucose is used during cellular respiration to produce energy while food (glucose) is made during photosynthesis.
