Why is light reaction of photosynthesis essential for the dark reaction to proceed?
why light reaction of photosynthesis is essential before the dark reaction can procced?
Which Photochemical reactions proceed only under the influence of light are called?
Photochemical reactions that only proceed under the influence of light are called photoreactions. This type of reaction involves the absorption of photons to initiate a chemical reaction. The rate and efficiency of photoreactions are typically dependent on the intensity and wavelength of light.
Is combution a reaction?
Yes, combustion is a chemical reaction in which a fuel (such as gasoline) reacts with an oxidizer (such as oxygen) to release energy in the form of heat and light. This reaction typically produces carbon dioxide and water as byproducts.
Does the dark reaction of photosynthesis require direct sun light energy to be proceed?
No, the dark reaction of photosynthesis (also known as the Calvin cycle) does not require direct sunlight energy to proceed. It is dependent on the products of the light reaction (ATP and NADPH) that are formed with the help of sunlight during the light-dependent reactions. These products are then used in the Calvin cycle to convert carbon dioxide into glucose.
When during the light reaction is the water molecule split?
The water molecule is split at the beginning of the light reaction, specifically in photosystem II. This splitting of water releases electrons, protons, and oxygen as byproducts, which are essential for the rest of the light-dependent reactions to occur.
What must a driver do when a yellow light is flashing at an intersection?
When a yellow light is flashing at an intersection, a driver must proceed with caution and be prepared to stop if necessary.
Why is possible for Calvin cycle to occur in the dark?
The Calvin cycle is called the dark cycle because it does not require light to proceed. Unlike light reactions, the Calvin cycle is a light-independent reaction, which means it can and will occur in the dark as well as the light.
Which type of chemical reaction often produces energy in the form of light heat or electricity?
Exothermic reactions often produce energy in the form of heat, light or electricity. These reactions release energy as they proceed, leading to a rise in temperature or the production of light.
Why is the second stage of photosynthesis called light independent reaction?
The light-independent reactions are sometimes referred to as the dark reactions, though that term may be misleading as they do not actually require darkness to proceed. The term "light-independent" is used to emphasize that the reactions occur regardless of the amount of light present as long as the proper substrate compounds are available. Even this term can be criticized, however, as the availability of substrates in plants depends on photosynthesis, so the reactions cannot be said to be entirely "light-independent." Furthermore, the term "dark reactions" may be more accurate in CAM (Crassulacean acid metabolism) plants, which only take up CO2, which is necessary for the reactions to proceed, at night.http://en.wikipedia.org/wiki/Light-independent_reaction
The chemical reaction that occurs when gasoline and air are ignited is called an?
The chemical reaction that occurs when gasoline and air are ignited is called combustion. This process releases energy in the form of heat and light, producing carbon dioxide and water as byproducts.
Is burning trash chemical reaction?
Yes, burning trash is a chemical reaction because it involves the combustion of organic materials releasing heat, light, and various chemical byproducts such as carbon dioxide, water vapor, and ash.
Why is the Dark Reaction sometimes called Light Independent Reaction?
Because the dark reactions are CO2 assimilation's and do not need light energy. They use the ATP and NADPH created from the light reactions to convert CO2 to carbohydrates, so this can happen in the "dark" as long as the light reactions already happened.
