How are photosynthesis and cellular respiration opposite in terms of carbon dioxide?
Answer (3)
Photosynthesis is the process by which plants take in (use) Carbon-dioxide and water to make food (starch). Photosynthesis: C_{6}H_{12}O_{6}+O_{2}"> C O 2 + H 2 0 + s u n l i g h t − − − − > C 6 H 12 O 6 + O 2 Cellular respiration is the process in which cells use oxygen to break down starch into energy molecules and give out Carbon-dioxide. Cellular respiration: CO_{2} + H_{2} 0 +energy"> C 6 H 12 O 6 + O 2 − − − − − > C O 2 + H 2 0 + e n er g y **
** So, in Photosynthesis, carbon-dioxide is taken in (used) and in cellular respiration, carbon-dioxide is thrown out (waste product)
Things that use Photosynthesis use carbon dioxide and release oxygen (like plants) Things that use cellular respiration use oxygen and release carbon dioxide (like humans)
Photosynthesis and cellular respiration are opposite processes regarding carbon dioxide: photosynthesis takes in CO₂ to produce glucose and oxygen, while cellular respiration consumes oxygen to break down glucose and releases CO₂ as a byproduct. Together, they form a cycle that supports life on Earth. This interdependence highlights how organisms rely on these vital processes for energy and growth.
