Why there are 12 molecules of water used in photosynthesis?
Water is important for photosynthesis because it the source of hydrogen for the sugars created through photosynthesis. The simple sugars created through photosynthesis have six carbon atoms, 12 hydrogen atoms and six oxygen atoms per molecule.
Why is water used in photosynthesis experiment?
During the process of photosynthesis, six molecules of carbon dioxide and six molecules of water react in the presence of sunlight to form one glucose molecule and six molecules of oxygen. The role of water is to release oxygen (O) from the water molecule into the atmosphere in the form of oxygen gas (O2).
How many water molecules are involved in photosynthetic equation?
6 water
Overall equation for photosynthesis 6 water water molecules are oxidized, and become the source of electrons for carbon dioxide reduction. 6 molecules of carbon dioxide are required, one for each carbon atom in glucose. 6 molecules of oxygen are produced as a by product of water oxidation.
Can you name some other parts where do you think photosynthesis may occur?
Leaves are the primary organs that carry out photosynthesis. There are other plant parts also, which perform photosynthesis such as modified stem, roots, etc. E.g. assimilatory roots contain chlorophyll and perform photosynthesis. They are aerial adventitious roots present in plants such as Trapa and Tinospora.
What happens to water in photosynthesis?
During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. This transforms the water into oxygen and the carbon dioxide into glucose. The plant then releases the oxygen back into the air, and stores energy within the glucose molecules.
Why do we need 12 molecules of water to make glucose?
To answer why 12 molecules of water are required, here is the explanation. Products of light reaction required in dark reactions to form one molecule of glucose are 12 molecules of NADPH and 18 molecules of ATP. Forming 2 molecules of NADPH from NADP+ , 2 molecules of water are required so that demand of 4 electrons and protons can be satisfied.
Why 1212molecules of H2O used as substrate?
12molecules of h2o used as substrate because in 12h2o there are 24 atoms of hydrogen and it has to split to form12 atoms of hydrogen in sugar and 12 atoms in water. The Terms and Conditions of our website have changed.
How many molecules of water are required to produce 12 molecules NADPH?
Two molecules of water split to form1 molecule of oxygen and the respective number of electrons and hydrogen ions are also formed as shown in the reaction given below. Now for producing 12 molecules of NADPH , total 12 molecules of water are required. Why are classification systems changing every now and then?
What is required for photosynthesis to occur in plants?
Some simple experiments you may have done in the earlier classes have shown that chlorophyll (green pigment of the leaf), light and CO 2 are required for photosynthesis to occur .
