Photosynthesis and Cellular Respiration Quiz

Organic molecules like glucose are broken down during cellular respiration to generate ATP, which powers cellular activities.

O2 is required for cellular respiration to generate ATP, while CO2 produced during respiration serves as a raw material for photosynthesis.

ATP generated through cellular respiration is crucial for providing energy needed to perform various cellular work, essentially powering life processes.
