What is light independent reaction for kids?
In photosynthesis, a light-independent reaction takes place in plant chloroplasts. In this process, sugars are made from carbon dioxide. The process, known as the Calvin cycle, uses products of the light-dependent reactions (ATP and NADPH) and various enzymes.
How do you define light-dependent reactions?
The light-dependent reactions use light energy to make two molecules needed for the next stage of photosynthesis: the energy storage molecule ATP and the reduced electron carrier NADPH. In plants, the light reactions take place in the thylakoid membranes of organelles called chloroplasts.
What is light reaction in simple words?
“Light reaction is the process of photosynthesis that converts energy from the sun into chemical energy in the form of NADPH and ATP.”
What is light independent reaction in biology?
Light-independent reaction (biology definition): Light-independent reaction is a series of biochemical reactions in photosynthesis not requiring light to proceed, and ultimately produce organic molecules from carbon dioxide.
What is an example of a light dependent reaction?
Calvin cycle Light-dependent Cycle happens in the thylakoid membrane of the chloroplast. In this reaction, by using water, chlorophyll absorbs the energy from the sun and transforms it into chemical energy. Water (H2O) is split and oxygen (O2) comes out as a by-product.
Where do light-dependent reactions occur?
Light-dependent reactions happen in the thylakoid membrane of the chloroplasts and occur in the presence of sunlight. The sunlight is converted to chemical energy during these reactions. The chlorophyll in the plants absorb sunlight and transfers to the photosystem which are responsible for photosynthesis.
What is an example of a light-dependent reaction?
What is the function of light reaction?
The overall function of light-dependent reactions, the first stage of photosynthesis, is to convert solar energy into chemical energy in the form of NADPH and ATP, which are used in light-independent reactions and fuel the assembly of sugar molecules.
What is the other name for light reaction?
The other name of light reaction is photo reaction.
What goes light dependent?
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 do the light independent reactions mean?
Freebase (4.00 / 1 vote)Rate this definition: Light-independent reactions The light-independent reactions of photosynthesis are chemical reactions that convert carbon dioxide and other compounds into glucose. These reactions occur in the stroma, the fluid-filled area of a chloroplast outside of the thylakoid membranes.
What does the word light dependent reactions mean?
A light-dependent reaction or light reaction is a chemical reaction that takes place in the presence of light. It is also known as ‘photolysis,’ meaning occurring in the presence of light. For example, plants use sunlight to prepare their food through photosynthesis, which is discussed in this article.
What are the major steps of light dependent reactions?
a plant converts energy from one form to another from solar energy to potential energy to chemical energy.
What are examples of light dependent reactions?
One very good example of Light Dependent Reaction is Photosynthesis and the product of the primary step of Photosynthesis is Oxygen, NADPH and ATP .
