What is light dependent reaction in photosynthesis?
The light-dependent reaction is a photochemical reaction taking place in the thylakoid membranes of chloroplasts, where light energy is transformed into adenosine triphosphate (ATP) and nicotinamide adenine dinucleotide phosphate (NADPH).
What is the stage of light dependent?
Photosynthesis takes place in two stages: the light-dependent reactions and the Calvin cycle. In the light-dependent reactions, which take place at the thylakoid membrane, chlorophyll absorbs energy from sunlight and then converts it into chemical energy with the use of water.
What is the photosynthesis equation?
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.
What is the chemical equation of the light-independent stage?
The light-independent reactions can be summarized as follows: 12 NADPH + 18 ATP + 6 CO2 yields C6H12O6 (glucose) + 12 NADP+ + 18 ADP + 18 Pi + 6 H2O.
What is the equation for light dependent reaction?
The light-dependent reactions convert light energy into chemical energy, producing ATP and NADPH. The light-dependent reactions can be summarized as follows: 12 H2O + 12 NADP+ + 18 ADP + 18 Pi + light and chlorophyll yields 6 O2 + 12 NADPH + 18 ATP.
What is the light-independent stage of photosynthesis?
In the light-independent reactions or Calvin cycle, the energized electrons from the light-dependent reactions provide the energy to form carbohydrates from carbon dioxide molecules. The light-independent reactions are sometimes called the Calvin cycle because of the cyclical nature of the process.
What is the overall equation of the light-dependent reactions?
Why is light dependent reaction important?
The overall purpose of the light-dependent reactions is to convert light energy into chemical energy. This chemical energy will be used by the Calvin cycle to fuel the assembly of sugar molecules. The light-dependent reactions begin in a grouping of pigment molecules and proteins called a photosystem.
What is the chemical equation of light reaction?
2 H2O 02 + 4e- + 4 H. Reduction of NADP. 2 NADP+ + 4e- + 4 H+ 2 NADPH + 2 H. ATP synthesis.
Who proposed photosynthesis equation?
Jan Ingenhousz and his discovery of the photosynthesis equation is celebrated in a Google Doodle. Jan Ingenhousz – the Dutch scientist who discovered the secrets of photosynthesis – is celebrated on what would have been his 287th birthday.
What are the reactants in light-dependent reactions?
Explanation: Light dependent reactions convert solar energy to chemical energy (in the form of ATP and NADPH). Sunlight and H2O are the reactant of the light dependent reaction. The sunlight is captured by photosystem II, and is used to excite electrons.
What are the light-dependent reactions reactants?
What happens in the light-dependent reactions of photosynthesis quizlet?
What happens during the light-dependent reactions? The light-dependent reactions use energy from sunlight to produce oxygen and convert ADP and NADP+ into the energy carriers ATP and NADPH. These reactions also produce oxygen as a by-product.
Where does the light dependent reaction occur?
The light-dependent reactions of photosynthesis take place within the thylakoids. These reactions occur when the pigment chlorophyll, located within the thylakoid membranes, captures energy from the sun (photons) to initiate the breakdown of water molecules.
What is the main product of light-dependent reactions?
The three products of light reaction of photosynthesis are ATP, NADPH and O2.
What is another name for light-dependent reactions?
The light-dependent reactions; The light-independent reactions, or Calvin Cycle.
What are the product of light-dependent reaction?
The products of the light-dependent reactions, ATP and NADPH, are both required for the endergonic light-independent reactions. The light-dependent reactions involve two photosystems called Photosystem I and Photosystem II.
Which is true about light dependent reaction?
Correct answer:
The light dependent reaction converts solar energy to chemical energy, using the photosystem to capture light energy, and ultimately produce ATP and NADPH. Pigment molecules in the photosystem absorb photons of light, which then reach the chlorophyll, exciting electrons in the chlorophyll.
When was photosynthesis equation discovered?
By 1845, the German physician Mayer was first able to write the basic photosynthesis equation for the conversion of light, water and CO2 into chemical energy, organic matter, and released oxygen.
Who is the father of photosynthesis?
Jan Ingenhousz
Jan Ingenhousz, Father of Photosynthesis, Celebrated With Google Doodle. Google celebrated Jan Ingenhousz’s 287th birthday on Dec. 8, 2017.
What is the equation for light-dependent reaction?
What is the equation for light reactions?
2 NADP+ + 4e- + 4 H+ 2 NADPH + 2 H. ATP synthesis. ADP + Pi ATP. When these equations are combined, the overall equation for the light reactions is obtained.
Where are light-dependent reactions?
In light-dependent reactions, the energy from sunlight is absorbed by chlorophyll and converted into chemical energy in the form of electron carrier molecules like ATP and NADPH. Light energy is harnessed in Photosystems I and II, both of which are present in the thylakoid membranes of chloroplasts.
What is the purpose of the light-dependent reaction quizlet?
-The purpose of the light-dependent reactions is to use water and light to produce ATP and NADPH or energy that the cell can use.
What is the function of the light-dependent reactions quizlet?
The overall function of light-dependent reactions is to convert solar energy into chemical energy in the form of NADPH and ATP.
