The light reaction can accomplish three things. Firstly, photoexcitation, basically what occurs in this process is the electron of chlorophyll absorb specific wave lengths of light. Secondly, we have electron transport, which pumps hydrogen to create a gradient that powers the ATP synthesis. And lastly there is chemosmosis, which is the movement of protons through ATP synthase complex that drives the phosphorylation of ATP.
What else can I help you with?
How is ATP produced during the light reaction in photosynthesis?
During the light reaction of photosynthesis, ATP is produced through a process called photophosphorylation. This process involves the conversion of light energy into chemical energy, which is used to add a phosphate group to ADP, forming ATP. This ATP is then used as an energy source for the dark reaction of photosynthesis, where carbon dioxide is converted into glucose.
How does the light harvesting complex contribute to the process of photosynthesis in plants?
The light harvesting complex in plants helps to absorb light energy and transfer it to the reaction center of photosystems, where it is used to drive the process of photosynthesis. This complex consists of pigments that capture light energy and pass it along to the reaction center, where it is converted into chemical energy to produce glucose and oxygen.
What starts light reaction in photosynthesis?
The light reaction in photosynthesis is initiated by the absorption of light by chlorophyll molecules in the thylakoid membranes of chloroplasts. This light energy is then used to split water molecules into oxygen, protons, and electrons, which kickstarts the process of energy production in the form of ATP and NADPH.
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 is dark reaction process?
* the second phase of photosynthesis, that does not require the presence of light, during which ATP releases stored energy that is used to convert carbon dioxide molecules into sugars and other nutrients * The dark reactions of photosynthesis doesn't require the presence of light to photosynthesize. * The second stage of photosynthesis, not requiring light to occur, and during which energy released from ATP drives the production of organic molecules from carbon dioxide. * there are 2 main stages in potosyntesis. the light reaction occurs only in the presence of light while dark reaction happens both when there is light and when it is dark.
What is the the process of plant respiration?
the respiriration is such a oxidative reductive process ... and during plant it have two complex more process consist of seriese of steps DARK reaction and Light reaction.................... dark reaction need no light wheather in day time or night time...................... some how the light reaction are done in the prescence of light ..........during the light reaction the formation of the light reaction is just one ATP Which is responsible for the production of dark reaction .............
Does light reaction process produce nadph?
no
What are the two basic steps to photosynthesis?
The Light Dependent process and then the Light Independent process (known as the Calvin Cycle).
How is light energy process in the light reaction of photosynthesis?
through an electron transport chain
What is the name of the process where the light is utilized to produce ATP?
The process is called photosynthesis. In photosynthesis, light energy is used by plants to convert carbon dioxide and water into glucose (energy) and oxygen.
What is the Light- independent reaction?
In scientific terms the light-independent reaction related to the process of photosynthesis which involves the conversion and reaction of carbon dioxide and other compounds to form Glucose.
Does the process of photosynthesis take place at night too.?
light reaction is not happening. Dark reaction could be.
Through which process is oxygen produced as a byproduct?
light-dependent reaction
What process does adenosine triphosphate occur?
it occurs in light independent reaction!!!
Is absorbing light a chemical reaction?
Light absorption is a physical process; but the effects of the absorption may be chemical.
The proper name for the light independent reaction is?
The proper name for the light-independent reaction is the Calvin Cycle. It is also known as the dark reaction or the carbon fixation process because it does not directly require light to occur.
Name two stages of photosynthesis?
There is the light-dependent stage, where sunlight interacts with choloropyll to set up an electron-transport chain, then there is the chemical stage, where glucose molecules are synthesized from CO2 and H2O.
