Why can the dark reaction occur in day light hours?
The dark reaction, also known as the Calvin cycle, can occur during daylight hours because it does not directly require light energy to proceed. It uses the ATP and NADPH generated during the light-dependent reactions to fix carbon dioxide and produce sugars. So even though it doesn't rely on light for its energy source, it still benefits from the products of the light-dependent reactions that happen during the day.
Why is the first stage called the light dependent reaction?
it is the first stage because the product of the light dependent reaction is ATP and NADPH+H+ (Nicotinamide Adenine Dinucleotide Phosphate Hydrogen) and these are required in the light independent reaction (calvin-benson cycle) I hope this helps :DDD
What is the name for light independent reactions?
Light-independent reactions are also known as carbon fixation.Are you talking about the Calvin Cycle/Dark Rxn's in chloroplasts?
What happens in the 'dark reaction' of photosynthesis?
Photosynthesis happens in two main stages, called the light-dependent stage and the light-independent stage. The light-independent stage is sometimes called the 'dark' stage. The light-dependent stage can only happen in the light. During this stage light is absorbed and turned into chemical energy (ATP). Oxygen is also produced. The light-independent stage can happen in the light or the dark ie it is independent of light! However, it needs substances made in the light-dependent stage so it cannot happen completely by itself. In the light-independent stage the energy trapped as ATP in the light-dependent stage is used to change carbon dioxide into sugar (glucose). The Calvin cycle converts carbon dioxide to carbohydrate. CO2 --------> (CH2O) This process requires an energy source and a hydrogen source, as well as carbon dioxide. The energy source is ATP. The hydrogen source is NADPH. Both of these substances are produced by the light-dependent reactions. For more details search this site for "calvin cycle", "light dependent" and l"ight independent".

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 another name for the dark reactions of photosynthesis?
Calvin cycle or light independent reaction
What is another name for the light independent reaction?
Light-independent reactions are also known as carbon fixation.Are you talking about the Calvin Cycle/Dark Rxn's in chloroplasts?
What is the proper name for combustion?
The proper name for combustion is a chemical reaction in which a substance reacts rapidly with oxygen, giving off heat and light.
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.

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
What is the proper name for a chemical reaction that gives out heat?
combustion
How did the light reaction get their name?
Because it happens only when light present
Why is the first stage called the light dependent reaction?
it is the first stage because the product of the light dependent reaction is ATP and NADPH+H+ (Nicotinamide Adenine Dinucleotide Phosphate Hydrogen) and these are required in the light independent reaction (calvin-benson cycle) I hope this helps :DDD
What is the name for light independent reactions?

Compare and contrast light dependent and light independent reactions of photosynthesis.?
Light-dependent reactions occur in the thylakoid membrane and require light energy to produce ATP and NADPH. Light-independent reactions (Calvin Cycle) occur in the stroma and use ATP and NADPH to convert CO2 into glucose. Both processes are essential for photosynthesis and occur in chloroplasts.
What is the name for the first and second stage of photosynthesis?
1st-Light reaction 2nd-Dark reaction
