Question

SEP Construct Explanations: Food contains chemical potential energy that the body uses. How do you think that the body gains this energy? Propose an explanation.

Answer 1

Answer:

Through oxidation of food materials

Explanation:

When living organisms eat, they ingest complex organic food materials. As these food materials enter the body, the process of digestion begins.

Enzymes in the body, located at different parts of the gastrointestinal tract see to the breakdown of these complex food materials ingested. The oxidation of these complex food materials lead to the release of the chemical potential energy stored in them.
