Water molecules
It comes from the splitting of water molecules.
Photosynthesis produces oxygen gas (O2) as a by-product. The oxygen comes from the splitting of water molecules at Photosystem II.
When oxygen is released as a result of photosynthesis, it is a by product of what?reducing NADP+chemiosmosisthe electron transfer system of photosystem Isplitting the water moleculesthe electron transfer system of photosystem IIsplitting the water molecules
The supply of electrons in photosynthesis comes from water.
Oxygen is one of the products of photosynthesis.
Oxygen is one of the by-products of photosynthesis. It comes from the breakdown of water molecules in plants during photosynthesis.
Plants produce oxygen when exposed to light. They do this by the process of photosynthesis. The oxygen comes from the splitting of water molecules to produce hydrogen ions and the oxygen is expelled as a waste product.
It comes from an underwater plant performing photosynthesis
The oxygen produced during photosynthesis comes directly from light from the sun. Oxygen is made by the plants interaction with carbon dioxide, water, and light energy.
Most but perhaps not all began when tiny organisms known as cyanobacteria, or blue-green algae (in the seas and oceans) began conducting photosynthesis: using sunlight, water and carbon dioxide to produce carbohydrates and oxygen.In fact, all the plants on Earth incorporate symbiotic cyanobacteria (known as chloroplasts) to do their photosynthesis for them today.
True
Water (H2O) is breaken down to hydrogen(H) and oxygen (O2)..
