Cellular respiration is a process where carbohydrates are broken down to release energy for cellular activities and CO2 is released as byproduct.

Animals breath in oxygen and exhale carbon dioxide a byproduct of cellular respiration.

Chemical equation 6 H 12 O 6 + 6 O 2 --> 6 CO 2 + 6 H 2 O + ATP
