Question

How do living organisms obtain energy from digested food?

Answer 1

The energy stored in food is released by the chemical oxidation of food. The energyliberated is the used to phosphorylate adenosine diphosphate molecules to adenosine triphosphate molecules (these are the molecules that store up theenergy that is used by the cells to drive its functions.

Answer 2

Animals obtain energy from the food they consume, using that energy to maintain body temperature and perform other metabolic functions. Glucose, found in the food animals eat, is broken down during the process of cellular respiration into an energy source called ATP. When excess ATP and glucose are present, the liver converts them into a molecule called glycogen, which is stored for later use.
