Why is water split during photosynthesis quizlet?
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 is Haber process used for?
The Haber Process is used in the manufacturing of ammonia from nitrogen and hydrogen, and then goes on to explain the reasons for the conditions used in the process. The process combines nitrogen from the air with hydrogen derived mainly from natural gas (methane) into ammonia.
What is Bosch process in chemistry?
The Bosch reaction is a chemical reaction between carbon dioxide and hydrogen that produces elemental carbon (graphite), water, and a 10% return of invested heat. … This reaction requires the introduction of iron as a catalyst and requires a temperature level of 530-730 degrees Celsius.
What is electrolysis of water Byjus?
Electrolysis of water is the chemical reaction in which the decomposition of hydrogen and oxygen gases is carried by passing an electric current. … It involves passing an electric current through the water which results in the decomposition of water into hydrogen and oxygen.
What does electrolyzed mean in chemistry?
electrolysis, process by which electric current is passed through a substance to effect a chemical change. The chemical change is one in which the substance loses or gains an electron (oxidation or reduction).
Which type of reaction is electrolysis of water?
Electrolysis of water is its decomposition to give hydrogen and oxygen gases due to the passage of an electric current.
What is splitting water used for?
Water splitting is an essential reaction in many technological applications, for example in fuel cells, solar energy production, and catalysis.
Why do people split water?
The splitting of water to produce hydrogen and oxygen gases (1−3) via renewable energy sources represents a carbon-free synthesis route to hydrogen gas, which finds use in a number of important applications, such as the hydrotreating of petroleum and biomass, the synthesis of ammonia and methanol, and the generation of …
What are called Assimilatory products?
ATP and NADPH2 are called assimilatory power. They are called so, because they provide the energy requirement for CO2 assimilation during dark reaction of photosynthesis.
What is dimorphic chloroplast?
Dimorphic chloroplasts are the chloroplasts which are concentrated into two types of cells having different size and structure. The dimorphic chloroplast is present in C4 plants because of the presence of special leaf anatomy called Kranz anatomy.
Why ATP is called Assimilatory power?
ATP and NADPH2 are formed during the light reaction of photosynthesis. These are used for the assimilation of CO2 and synthesis of carbohydrates in the Calvin cycle ( dark reaction), so ATP and NADPH2 are known as assimilatory power.
What process splits water molecules and what are the end products of this process?
In a process called photolysis (‘light’ and ‘split’), light energy and catalyst s interact to drive the splitting of water molecules into protons (H+), electrons, and oxygen gas.
What is called stroma?
Stroma, in botany, refers to the colorless fluid surrounding the grana within the chloroplast. Within the stroma are grana (stacks of thylakoid), and the sub-organelles or daughter cells, where photosynthesis is commenced before the chemical changes are completed in the stroma. Photosynthesis occurs in two stages.
