How is ATP used in photosynthesis? - Quora
For each electron flowing from water to NADP+ (a net change in1.14 volts), two quanta of light are absorbed, one by eachPhotosystem. Each molecule of oxygen released involves the flowof four electrons from two water molecules to two NADP+s andrequires four quanta of sunlight absorbed by each Photosystem toprovide the energy to do this. These are the "Light PhaseReactions" of photosynthesis, which produce two high energychemical products, namely NADPH and ATP.
With stomata open only at night when the temperature is lower and the relative humidity higher, the CAM plants use much less water than either or C4 plants. Some varieties convert to C3 plants at the end of the day when their acid stores are depleted if they have adequate water, and even at other times when water is abundant.
Why is ATP produced in photosynthesis used to synthesize glucose
Light Dependent Reactions
The reactants of cellular respiration are: Oxygen and Glucose (Sugar)
Electron Transport Chain
ATP (Adenosine Triphosphate) is one of the principal chemical compounds that living things use to store and release energy
ADP (Adenosine Diphosphate) is an important organic compound in metabolism and is essential to the flow of energy in cells
3 Phosphate groups
When the chlorophyll molecule is excited by light, the energylevel of an electron in its structure is "boosted to ahigher energy level and this "excited" chlorophyll (nowis called an ) moves rapidly the the reactioncenter of the Photosystem I where it transfers its extra energyto an electron which is then expelled from the reaction centerand is accepted by the first member of a chain of electroncarriers and ultimately reaches NADP+, reducing it to NADPH. Thereaction center has lost an electron and this "electronhole" is filled by by stripping electrons from water whichleaves hydrogen ion (H+) and molecular oxygen (O2). The pathwayof electrons from water to NADP+ has "Z" shape whendiagramed and is refered to as the Z Scheme.
How is ATP used in photosynthesis? | Yahoo Answers
Sugarcane is a champion at photosynthesis under the right conditions and is a prime example of a C4 plant, one which uses C4 photosynthesis. Sugarcane has been recorded at 7% .
Photosynthesis is defined as the formation of carbohydrates inliving plants from water and carbon dioxide (CO2). It is the mostimportant chemical pathway (series of chemical reactions) on ourplanet. Almost all of the biomass on Earth was initially createdby photosynthesis.

Photosynthesis converts these energy- depleted compounds (ADPand NADP+) back to the high energy forms (ATP and NADPH) and theenergy thus produced in this chemical form is utilized to drivethe chemical reactions necessary for synthesis of sugars andother carbon containing compounds (e.g., proteins, fats). Theproduction of high energy ATP and NADPH in plants occurs in whatis known as Light Phase Reactions (Z Scheme) (requiressunlight). The energy releasing reactions which converts themback to energy-depleted ADP and NADP is known as Dark PhaseReactions (Calvin Cycle) (does not require light) in whichthe synthesis of glucose and other carbohydrates occurs.

The CAM plants represent a metabolic strategy adapted to extremely hot and dry environments. They represent about 10% of the plant species and include cacti, orchids, maternity plant, wax plant, pineapple, Spanish moss, and some ferns. The only agriculturally significant CAM plants are the pineapple and an Agave species used to make tequila and as a source of fiber.
What is the function of the chlorophylls in photosynthesis yahoo
The oxidative chemical reactions of respiration releaseenergy, some of which is heat and some of it is captured in theform of high energy compunds such as Adenosine triphosphate (ATP)and Nicotinamide adenide dinucleotide phosphate (NADPH). Thesecompounds have a high energy (unstable) terminal phosphate bondand that terminal phosphate is easily detached with the transferof the energy to drive chemical reactions in the synthesis ofother biomolecules. In this case, the ATP loses one phosphate tobecome the energy-depleted ADP (Adenosine diphosphate)and the NADPH loses one electron to become energy-depleted NADP+.
In photosynthesis ATP is produced in light ..
Most leaves are flat and contain ; their main function is to convert energy from sunlight into chemical energy (food) through photosynthesis.
- the part of the stem of a plant from which a leaf, branch, or aerial root grows; each plant has many nodes.
