What is the oxygen produced in photosynthesis used for?
Plants actually hold on to a small amount of the oxygen they produced in photosynthesis and use that oxygen to break down carbohydrates to give them energy.
Is oxygen produced or used in photosynthesis?
Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar.
How is the oxygen produced during photosynthesis?
During the light reactions, an electron is stripped from a water molecule freeing the oxygen and hydrogen atoms. The free oxygen atom combines with another free oxygen atom to produce oxygen gas which is then released.
What happens to the oxygen that is released during photosynthesis?
The oxygen released during photosynthesis is from the water. The plants will absorb water as well as carbon dioxide during photosynthesis. Later these water molecules are converted into oxygen and sugar. The oxygen is then released into the atmosphere whereas the sugar molecules are stored for energy.
How is oxygen produced during photosynthesis quizlet?
The oxygen released during photosynthesis comes from the splitting of water during the light-dependent reaction. Light ”excites” electrons in pigment molecules, and light provides the energy to split water molecules, providing more electrons as well as hydrogen ions.
What stage of photosynthesis is oxygen produced?
The Light Reactions
The Light Reactions The energy is then temporarily transferred to two molecules, ATP and NADPH, which are used in the second stage of photosynthesis. ATP and NADPH are generated by two electron transport chains. During the light reactions, water is used and oxygen is produced.
How is oxygen produced?
The most common commercial method for producing oxygen is the separation of air using either a cryogenic distillation process or a vacuum swing adsorption process. Nitrogen and argon are also produced by separating them from air. This method is called electrolysis and produces very pure hydrogen and oxygen.
