Differentiate light reaction dark?
light reactions in plants takes place in the sun.reactions which occur after the light reactions are dark reactions.
How do the reactions and Calvin cycle work together to build glucose?
The light reactions provide the energy carriers used in the Calvin cycle
What takes place during photosynthesis?
Light energy is converted into chemical energy. Photosynthesis is divided into two reactions (light reaction and light independent reaction) and they work together to make glucose, which can then be used by the cell.
What is the importance of light in photosynthesis?
The equation of photosynthesis is as below:Carbon dioxide + Water ---------> Glucose + OxygenThis reaction takes place in the presence of light and chlorophyll.The process of photosynthesis is completed in two stages:-Light Reactions: When light falls on leaves, it is absorbed by the chlorophyll in the chloroplasts. The solar energy is utilized to split water into oxygen and hydrogen, this process is called photolysis, and oxygen is released during this process. As these reactions take place only in the presence light, they are called light reactions.During light reactions two compounds are formed when solar energy is converted into chemical energy, these are:NADPH (Nicotinamide Adenine Di-nucleotide Phosphate)ATP (Adenosine Tri-Phosphate)NADP already exists in the cells of the leaf. The hydrogen released on the photolysis of water molecule is accepted by this compound and it becomes reduced to form NADPH.NADP (in cell) + H (from water) ---------> NADPHThis reaction takes place in the presence of light and enzymes.The compound ADP (Adenosine Di-Phosphate) is already present in the cells of the leaf and combines with the phosphate group using light energy to form a compound called ATP.ADP + P ---------> ATPThis reaction also takes place in the presence of light and enzymes.These compounds are energy rich and are needed for the dark reactions in photosynthesis.Dark Reactions: Utilizing the energy from ATP and the hydrogen from NADPH, water combines with carbon dioxide to form carbohydrates. Thus, the solar energy is now converted into chemical energy to form glucose. Other organic compounds are further synthesized from this glucose.This stage is also completed in a series of chemical reactions with the help of enzymes . Scientists have discovered an interesting thing about these two stages: only the first requires light, and the second can occur in the dark. So we call these reactions light and dark reactions respectively. Neither light energy nor chlorophyll are required for the dark reactions.Various steps of the dark reactions were studied by a scientist named Melvin Calvin, thus dark reactions are also known as Calvin's Cycle. When scientists performed experiments with chlorella plant, they found the rate of photosynthesis increased in non-continuous supply of light and again if the temperature is raised during dark reactions, the rate increases invariably. This also proved that light reactions are photochemical reactions which involve light, and dark reactions are chemical reaction which do not involve light.
How do photosystem 1 and 2 allow the calvin cycle to work?
No. Photosystems I and II are where light-dependent reactions occur, while the Calvin Cycle is where light-independent reactions occur. Photosynthesis begins with Photosystem II, then Photosystem I, then the products from there go to the Calvin Cycle. (yes photosystem II comes before photosystem I)
How the light and dark reactions work together?
The light reactions provide energy carriers for the dark reactions.
How do light an dark reactions work together?
The light reactions provide energy carriers for the darl reactions.
Differentiate light reaction dark?
light reactions in plants takes place in the sun.reactions which occur after the light reactions are dark reactions.
How do the light and dark Reaction work?
The light reactions provide energy carriers for the dark reactions.
How does light dependent and light independent reaction work together?
The Light Reactions Provide Energy Carriers For The Dark Reactions.
Do the dark reactions occur in the thylakoids?
A dark reaction is done in the Calvin Cycle. Light is not needed at the time of the dark reaction but it also doesn't hinder the reaction if there is light at the time.So in short. Yes.
How do the reactions and Calvin cycle work together to build glucose?

How do the light reactions and Calvin cycle work together to build glucose?
The light reactions provide the energy carriers used in the Calvin cycle
How can endothermic and exothermic reactions work together?
they work together by producing more heat or thermal energy.
Does the Calvin cycle work in the light or the dark?
darkIt works both in light and dark. It does not need light to operate
Which watch work the best in the dark?
Any watch with a glow in the dark or a light up feature will work well in the dark.
