Question

Does cellular respiration require a net input of energy or result in a net release of energy? Use mathematical evidence to support your response.

a) Net input of energy, as C6H12O6 + 6O2 → 6CO2 + 6H2O + ATP
b) Net release of energy, as C6H12O6 + 6O2 → 6CO2 + 6H2O + ATP
c) Net input of energy, as 6CO2 + 6H2O → C6H12O6 + 6O2 + ATP
d) Net release of energy, as 6CO2 + 6H2O → C6H12O6 + 6O2 + ATP

Answer 1

Cellular respiration results in a net release of energy. The process converts carbohydrates and oxygen into carbon dioxide, water, and ATP.

Step-by-step explanation:

Cellular respiration refers to a set of chemical reactions that convert carbohydrates and oxygen into carbon dioxide, water, and ATP. The overall equation for cellular respiration is C6H12O6 + 6O2 → 6CO2 + 6H2O + ATP.

Hence, cellular respiration results in a net release of energy. The process occurs in three stages: glycolysis, the Krebs cycle, and the electron transport chain.
