Why are light reactions required for the photosynthetic process?
Wiki User
∙ 9y ago
Chloroplasts convert light energy into chemical energy. The energy of light captured by pigment molecules, called chlorophylls, in chloroplasts is used to generate high-energy electrons with great reducing potential.

What are the two main stages for photosynthesis?
The light dependent stage and the light independent stage.
How is light produced by phosphorescence?
In simple terms, phosphorescence is a process in which energy absorbed by a substance is released relatively slowly in the form of light. This is in some cases the mechanism used for "glow-in-the-dark" materials which are "charged" by exposure to light. Unlike the relatively swift reactions in a common fluorescent tube, phosphorescent materials used for these materials absorb the energy and "store" it for a longer time as the processes required to re-emit the light occur less often. I hope that answers your question!
Why is the sun the most important form of energy to most organisms?
All the green plants and photosynthetic microbes produce their food by photosynthesis procedure and all other organisms placed at higher levels in food chain get the energy from them. Some "Chemo synthetic" bacterium species get energy from chemical reactions,but for that the coordination from photosynthetic reaction is required. So,we can't imagine the living world possible without the sun.
Is medium required to transmit light waves?
No. light waves required no medium for transmission.
What is the difference between nuclear energy and light energy?
Light is electromagnetic energy. Nuclear energy is energy derived from nuclear reactions, and the nuclear reactions could be either fusion or fission reactions. As regards the energy that appears from nuclear reactions, it can take different forms, including the form of electromagnetic energy.
What photosynthetic products created by light reactions are required by dark reactions?
ATP and NADPH2
What is a series of photosynthetic reactions in which carbon dioxide is fixed and reduced in chloroplast?
light-dependant reactions
What is light harvesting?
light harvesting is a set of photosynthetic pigment molecules that absorb light and channel the energy to the photosynthetic reaction centre, where the light reactions of photosynthesis occur.
What are the stage in the process of photosynthesis?
Photosynthesis is performed in two stages:Light reactions (or light-dependent reactions): Energy from sunlight is required.Dark reactions (or light-independent reactions): No sunlight is required. However, energy formed by the light-dependent reactions is needed.
Are photosynthetic pigments a part of the light dependent or light independent reactions?
The light dependent reaction, of course.
What are two stages in the process of of photosynthesis?
Photosynthesis is performed in two stages:Light reactions (or light-dependent reactions): Energy from sunlight is required.Dark reactions (or light-independent reactions): No sunlight is required. However, energy formed by the light-dependent reactions is needed.
What photosynthetic reactions that can be taken out in the absence of light?
The Calvin Cycle. This is why it is sometimes called the "Light independent reaction".
What is a photosynthetic unit?
A photosynthetic unit is a unit that carries out photosynthesis. It would be an organelle of a plant cell, a chloroplast. The cholorphyll the green pigment in the chloroplasts absorb the light and through the light dependent reactions and light independent reactions carbon dioxide and water is converted into glucose
What structures do light-independent reactions of photosynthesis take place?
Light-independent reactions take place outside the thylakoids, in the stroma. The stroma is the fluid part of the chloroplast. The thylakoids are an abundance of saclike photosynthetic membranes.
Light-dependent reactions of photosynthesis?
The light-dependent reactions, or light reactions, are the first stage of photosynthesis. In this process light energy is converted into chemical energy, in the form of the energy-carriers ATP and NADPH. In the light-independent reactions, the formed NADPH and ATP drive the reduction of CO2 to more useful organic compounds, such as glucose.
What is required for the light reactions?
water, and sunlight
What is the function of the photosynthetic system?
To take CO2 from the air and turn it into oxygen that we can breathe. Their are light dependent and independent reactions.
