During these reactions, light energy is used to split water molecules into hydrogen ions and oxygen gas. The hydrogen ions are then used to produce ATP, a molecule that stores energy. The oxygen gas is released into the atmosphere.<\/p>\n<p>The Calvin cycle takes place in the stroma of chloroplasts. During this cycle, carbon dioxide is used to produce glucose. The ATP and NADPH produced during the light-dependent reactions are used to power the Calvin cycle.<\/p>\n<p>The overall reaction for photosynthesis is:<\/p>\n<p>6CO2 + 6H2O + light energy \u00e2\u0086\u0092 C6H12O6 + 6O2<\/p>\n<p>As you can see from the equation, the oxygen gas released during photosynthesis comes from water.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Subscribe on YouTube<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[15],"tags":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v22.2 (Yoast SEO v23.3) - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>O2 released in the process of photosynthesis comes from A.
