Science Assessment ~ Ideas ~ The energy released from food was once energy from the sun that was captured by plants in the chemical process that forms plant matter (from air and water).

Key Idea: Cellular respiration in animals involve chemical reactions during which carbon-containing molecules react with oxygen and produce carbon dioxide and water and release stored energy.

Students are expected to know that:

Food consists of carbon-containing molecules in which carbon atoms are linked to other carbon atoms.
Carbohydrates (including simple sugars and starch), fats, and proteins are molecules that are food.
During cellular respiration, the food molecules and oxygen molecules are broken apart and the atoms are put back together to form carbon dioxide and water.
During cellular respiration, energy is released and used by the animal to carry out life functions.

Boundaries:

Assessment does not include details of the chemical reactions related to cellular respiration.
