WebbRT @Steely_Jan: is even possible: it is a perfectly balanced & self-sufficient ecosystem. … Webb25 apr. 2015 · Water is the source of the oxygen released in green plant photosynthesis (not CO 2) In the reduction of CO 2, six carbon-carbon and six carbon-hydrogen bonds are 'made' (thus accounting for the requirement of 12 reducing equivalents). The reduction of 6 CO 2 produces six water molecules as a by-product.

WebbRT @Steely_Jan: is even possible: it is a perfectly balanced & self-sufficient ecosystem. The bacteria in the compost eats the dead plants & breaks down the oxygen released by the plants, turning it into carbon dioxide, which is needed for photosynthesis.

6.6: Photosynthesis - Biology LibreTexts
Photosynthetic oxygen evolution is the fundamental process by which oxygen is generated in the earth's biosphere. The reaction is part of the light-dependent reactions of photosynthesis in cyanobacteria and the chloroplasts of green algae and plants. It utilizes the energy of light to split a water molecule into its protons and electrons for photosynthesis. Free oxygen, generated as a by-product of this reaction, is released into the atmosphere. WebbThe oxygen so released is used in the respiration process to break down complex … WebbThe evolution of photosynthesis refers to the origin and subsequent evolution of ...
