Question

cells produce carbon dioxide waste in what chemical process? all of these photosynthesis cellular respiration gas exchange

Explanation:

• Photosynthesis: Plants use carbon dioxide to make glucose, so it does not produce carbon dioxide as a waste.
• Gas exchange: It is the process of exchanging gases (like oxygen and carbon dioxide) between an organism and its environment, not a process that produces carbon dioxide waste in cells.
• Cellular respiration: In cellular respiration, cells break down glucose (and other molecules) to produce energy (ATP), and carbon dioxide is a waste product of this process (the equation is \( C_6H_{12}O_6 + 6O_2

ightarrow 6CO_2 + 6H_2O + \text{energy} \)).

• "All of these" is incorrect because photosynthesis and gas exchange do not produce carbon dioxide as a waste in the way the question asks (at the cellular chemical process level for waste production).

Answer:

Cellular respiration (the option with "Cellular respiration" text)
