Answer:
The correct answer is - cellular respiration is the process to release energy from food in the form of ATP.
Step-by-step explanation:
Food, as we know, is the only source of energy for the body but it requires to converted from the form of what we eat which is carbohydrates, protein, fat into an energy source that cells and the body can use for various functions. The process that converts food into energy is cellular respiration.
Cellular respiration is a set of complex chemical reactions that convert sugars into energy in the form of ATP which is the only currency of energy cell can use. The reaction has three stages glycolysis converts glucose in pyruvate, Krebs cycle releases carbon in the form of CO2 from pyruvate, and electron transport which is oxygen-dependent reaction.
Cellular respiration can be understood by the following chemical equation:
C6H1206 + 6O2 ====> 6CO2 + 6H2O + ATP
