Cellular Respiration and Photosynthesis Quiz

Organisms get the energy they need from their food.

Cellular respiration is the process that releases energy from food in the presence of oxygen.

6O2 + C6H12O6 --> 6CO2 + 6H2O + Energy (ATP)

<p>Photosynthesis removes carbon dioxide from the atmosphere, and cellular respiration puts it back. Photosynthesis releases oxygen into the atmosphere, and cellular respiration uses that oxygen to release energy from food.</p> Signup and view all the answers
