What happens to the oxygen gas released in 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.
Where is o2 generated during the light reactions?
thylakoid space
Oxygen and hydrogen ions are also formed from the splitting of water. To replace the electron in the reaction center, a molecule of water is split. This splitting releases an electron and results in the formation of oxygen (O2) and hydrogen ions (H+) in the thylakoid space.
Does the light reaction produce oxygen?
During the light reactions, water is used and oxygen is produced. These reactions can only occur during daylight as the process needs sunlight to begin.
What happens to oxygen that is produced?
Green plants use some of the oxygen they produce for their own life processes. But they release most of the oxygen produced during photosynthesis into the air as a waste product. They release the carbon dioxide into the air as a waste product. Plants help animals and animals help plants.
At what point in photosynthesis is oxygen released?
The oxygen released during photosynthesis comes from the splitting of water during the light-dependent reaction. 3. Remember, the electrons lost from the reaction center in photosystem II must be replaced. The splitting of water serves to replace these lost electrons.
What gas is formed from the action of light and oxygen?
Oxygen atoms are created during the light process of photosynthesis, and two oxygen atoms then combine to form oxygen gas.
Where does light reaction occur?
The light reaction takes place in the thylakoid discs. There, water (H20) is oxidized, and oxygen (O2) is released. The electrons freed up from water are transfered to ATP and NADPH. The dark reaction occurs outside of the thylakoids.
What is the significance of light reaction?
The main purpose of the light reaction is to generate organic energy molecules such as ATP and NADPH which are needed for the subsequent dark reaction. Chlorophyll absorbs the red and blue segment of the white light and photosynthesis occurs most efficiently at these wavelengths.
What happens to oxygen produced by light dependent reactions?
Which of the following explains what happens to oxygen produced by the light-dependent reactions? A. It is used in the Calvin Cycle B. It is released into the atmosphere C. It combines with NADPH to produce water D. It is recycled as a reactant in another light-dependent reaction B.
How is oxygen gas produced during photosynthesis?
Oxygen atoms are created during the light process of photosynthesis, and two oxygen atoms then combine to form oxygen gas.
Which is the primary purpose of light reactions in photosynthesis?
1 Light Reactions. The primary purpose of the light reactions in photosynthesis is to generate energy 2 Cyclic and Noncyclic Photophosphorylation. 3 Chloroplasts. In photosynthetic eukaryotes such as algae and plants, 4 Photosystems. Photosystems are complex structures of involving pigments located within
How does the formation of oxygen take place?
Oxygen Formation. As electrons are stripped from water molecules, the water is broken into component atoms. The oxygen atoms from two water molecules combine to form diatomic oxygen (O2). The hydrogen atoms, which are single protons missing their electrons, aid the creation of the proton gradient within the space enclosed by the thylakoid membrane.
