Why are 12 water molecules 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. The source of carbon is carbon dioxide gas from the air.
Can you explain why twelve molecules of water as substrate are used in the equation given below?
Answers. The process of photosynthesis for the fixation of 6 carbon dioxide molecules will always release 6 oxygen molecules and as we know that the oxygen is evolved from water, therefore for the evolution of 6 molecules of oxygen we definitely require 12 molecules of water.
What is the water molecule used for in the photosynthesis reaction?
In the process of photosynthesis, water provides the electron that binds the hydrogen atom (of a water molecule) to the carbon (of carbon dioxide) to give sugar (glucose).
How many water molecules are used in one cycle of photosynthesis?
6 water water molecules
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.
Why do water molecules split during photosynthesis?
Water is absolute requirement for photosynthesis to occur. During Light reactions of Photosynthesis, the chlorophyll will be activated by light. Water molecule is split to release H+ ions and also oxygen.
What is the role of water in photosynthesis Class 10?
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 molecules are needed for photosynthesis?
The process of photosynthesis is commonly written as: 6CO2 + 6H2O → C6H12O6 + 6O2. This means that the reactants, six carbon dioxide molecules and six water molecules, are converted by light energy captured by chlorophyll (implied by the arrow) into a sugar molecule and six oxygen molecules, the products.
How is water used in photosynthesis quizlet?
What role does water play in photosynthesis? Water provides the electrons and hydrogen ions needed to power the light-dependent and light-independent phases of photosynthesis. NADPH plays a big role in the light-independent reaction when it is used, along with ATP, to produce high energy sugars.
