Matter Unit Test

In 3-5 sentences, describe cellular respiration and identify reactants and products. Explain where the energy comes from and how it
is stored. (4 points)

Answer 1

Cellular respiration is a biological process that cells use to extract energy from organic compounds, such as glucose. The reactants of cellular respiration are glucose and oxygen, while the primary products are carbon dioxide, water, and ATP molecules. Energy is stored in the chemical bonds of ATP molecules and is released when those bonds are broken during cellular processes that require energy. The energy ultimately comes from the sun, as the glucose was produced through photosynthesis using sunlight.
