Oxygen primarily comes from photosynthesis, a process carried out by plants, algae, and certain types of bacteria. During photosynthesis, these organisms use sunlight to convert carbon dioxide and water into glucose and oxygen. This oxygen is released into the atmosphere as a byproduct of this process, which is essential for respiration in animals and many other living organisms.
Approximately 50-85% of the Earth's oxygen comes from marine plants, such as algae. While algae in the ocean play a significant role in oxygen production, the majority of the Earth's oxygen supply actually comes from terrestrial plants and phytoplankton.
The oxygen produced during photosynthesis comes directly from water. In the light-dependent reactions of photosynthesis, water molecules are split to release oxygen as a byproduct. This process is known as photolysis.
Oxygen in oxidative phosphorylation comes from the air we breathe. During the electron transport chain, oxygen acts as the final electron acceptor, combining with protons to form water. This reaction is essential for the generation of ATP, the energy currency of the cell.
The oxygen atoms in the oxygen gas produced by photosynthesis come from water molecules that are split during the light-dependent reactions. The oxygen molecules released are a byproduct of this process.
The oxygen for cellular respiration comes from the air we breathe, which contains about 21% oxygen. During respiration, oxygen is taken up by cells in the body and used in the mitochondria to produce energy in the form of ATP.
Oxygen comes from trees you need oxygen to breath
Very it is everywhere almost like the of oxygen it comes bodies and oxygen comes from trees
oxygen
Glucose comes from the leaves and tree bark they eat. Oxygen comes from the air they breath.
Approximately 50-85% of the Earth's oxygen comes from marine plants, such as algae. While algae in the ocean play a significant role in oxygen production, the majority of the Earth's oxygen supply actually comes from terrestrial plants and phytoplankton.
oxygen is not a compound it is a diatomic (that means the element comes in pairs)
a lot of oxygen! that's where most of it comes from!
Oxygen is one of the products of photosynthesis.
oxygen
We have trees so we can breath and that happens because when we breath in all the oxygen comes inside us and when we breath out all the oxygen comes out of us.
The majority of the Earth's oxygen comes from phytoplankton and terrestrial plants through the process of photosynthesis. Phytoplankton in the oceans are estimated to produce about 50-85% of the world's oxygen.
About 50-80% of the Earth's oxygen comes from algae, with the majority being produced by phytoplankton in the oceans. Algae are vital for oxygen production through photosynthesis, which converts carbon dioxide into oxygen as a byproduct.
