Q: In addition to glucose, what gas is used during cellular respiration?


Read this paragraph and choose the correct option from the provided answers:

Cellular respiration uses oxygen in addition to glucose. It releases carbon dioxide and water as waste products. Cellular respiration actually "burns" glucose for energy. However, it doesn't produce light or intense heat like burning a candle or log. Instead, it releases the energy slowly, in many small steps. The energy is used to form dozens of molecules of ATP.

oxygen
