Question

When Anna eats an apple, the sugars in that apple are broken down into the substance called glucose. Glucose is then burned in her body for energy. One of the body parts that needs this energy is the heart, which beats due to electrical impulses. A byproduct of this glucose breakdown is the heat that warms her body and is later released.

Which identifies the energy transformations that take place in Anna’s body as this process takes place?

Chemical energy is converted to thermal energy and electrical energy.
Electrical energy is converted to chemical energy and thermal energy.

Answer 1

The first statement is correct.

Explanation: The apple’s sugars (chemical energy) are broken down (cellular respiration) and converted into usable energy, part of which becomes electrical energy (the heart’s impulses) and part is released as thermal energy (heat).
