Photosynthesis occurs in 2 parts- The light reactions and the Calvin Cycle. The light cycle is dependent on light. Within the chloroplast, are sacs of organelles called thylakoids. (A stacked bundle of these are called Granum.) The Thylakoids membranes contain chlorophyll. The chlorophyll is a pigment that absorbs the light from the sun.now for the steps of the light reactions. 1.)The light absorbed by chlorophyll causes a transfer of electrons and H+ from H20 molecules already present. This causes the H20 to split into molecular 0xygen (02) and a H+ ion. 2.) The O2 is released (we breathe it) and the H+ bonds to NADP+ creating NADPH 3.)ATP is formed through photophosphorylation. (ADP gets a phosphate group added to it creating ATP) 4.) The NADPH and the ATP created here go on to fuel the reactions in the second part of photosynthesis - The Calvin Cycle

Normally reactions that depend on enzymes are strongly temperature-dependent. Are the carbon-assimilating steps dependent on enzymes?
The influence of specific enzymes is strongly dependent on environmental conditions.
What are the two steps in photosynthisis?
Light reactions and the Calvin Benson Cycle.
Is ATP produced in both photosynthesis and respiration?
Yes and No. There are two parts of photosynthesis, the light reactions and Calvin cycle. The light reactions produce ATP and NADPH which the Calvin reactions then use to produce sugars. So yes in respration 32-38 ATP are produced. And yes ATP is made by the light rxns in photosynthesis but is not a final product like the ATP in respiration
What is dark face 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). There are more details to this process which I have covered in another answer: http://wiki.answers.com/Q/What_connects_the_light_dependent_reaction_to_the_light_independent_reaction See also: http://www.phschool.com/science/biology_place/biocoach/photosynth/calvin1.html
What process of photosynthesis can occur even when there is no light?
The Dark Reactions (a.k.a. The Calvin Cycle) can occur without the light. Sometimes they are also called the Light Independent Reactions for that very reason. Light is required during the light reactions because the energy from light (photon) is required to excite electrons. No such energy source is required for the Calvin Cycle because the energy has already been converted into a chemical form (ATP and NADPH) during the light reactions. The energy from ATP and NADPH is used to "drive" the Calvin Cycle (the accumulation of Carbon atoms from Carbon Dioxide). Carbon Dioxide and Rubulose Biphosphate (RuBp) are combined using the enzyme rubisco. The energy from ATP and NADPH is added (in several steps). The final molecule, gyceraldehye-3-phosphate (G3P) is produced. There is a fairly common misconception that glucose is the final product of the Calvin Cycle; but, it is actually G3P. Notice that none of these reactions (those of the Calvin Cycle) required light. And don't forget, plants don't need light for cellular respiration either.
What are two phrases in photosynthesis?

What are the two steps in photosynthisis?
Light reactions and the Calvin Benson Cycle.
What are the steps in light-dependent reaction?
Oxygen turns into six part carbon sugars
Is ATP produced in both photosynthesis and respiration?
Yes and No. There are two parts of photosynthesis, the light reactions and Calvin cycle. The light reactions produce ATP and NADPH which the Calvin reactions then use to produce sugars. So yes in respration 32-38 ATP are produced. And yes ATP is made by the light rxns in photosynthesis but is not a final product like the ATP in respiration

What the functions of NADPH?
An easily understood explanation is: NADPH carries high-energy electrons that were produced by light absorption in chlorophyll to chemical reactions elsewhere in the cell. NADPH is a chemical compound which gives hydrogen atom for the formation of the carbohydrate in the dark reactions of the photosynthesis. Photosynthesis is completed in two steps: Light reactions dark reactions Another explanation: NADPH provides a source of hydrogen for reduction reactions in photosynthesis. In the light independent reactions carbon dioxide is converted into carbohydrate: CO2 --------> CH2O NADPH provides the hydrogen needed for this reaction.
