what is photosynthesis?
960590
Photosynthesis (photo=light, synthesis=putting together), generally, is the synthesis of sugar from light, carbon dioxide and water, with oxygen as a waste product. It is arguably the most important biochemical pathway known; nearly all life depends on it. It is an extremely complex process, comprised of many coordinated biochemical reactions. It occurs in higher plants, algae, some bacteria, and some protists, organisms collectively referred to as photoautotrophs.

Photosynthesis uses the energy of light to make the sugar, glucose. A simple general equation for photosynthesis follows...\n\n      6 CO2 + 12 H2O  light → C6H12O6 + 6 O2 + 6 H2O\nCarbon Dioxide+Water+Light energy → Glucose+Oxygen+Water\n\nPhotosynthesis occurs in two stages. In the first phase light-dependent reactions or photosynthetic reactions (also called the Light reactions) capture the energy of light and use it to make high-energy molecules. During the second phase, the light-independent reactions (also called the Calvin-Benson Cycle, and formerly known as the Dark Reactions) use the high-energy molecules to capture carbon dioxide (CO2) and make the precursors of glucose.\n\nIn the light-dependent reactions the pigment chlorophyll absorbs light and loses an electron that travels down an electron transport chain producing the high energy molecules NADPH and ATP. The chlorophyll molecule regains its electron by taking one from water, a process that releases oxygen gas.\n\nIn the Light-independent or dark reactions the enzyme RuBisCO captures CO2 from the atmosphere and in a complex process called the Calvin-Benson cycle releases 3-carbon sugars which are later combined to form glucose.\n\nLight to chemical energy---\nThe light energy is converted to chemical energy using the light-dependent reactions. The products of the light dependent reactions are ATP from photophosphorylation and NADPH from photoreduction. Both are then utilized as an energy source for the Light independent reactions.\n\nZ scheme---\nIn plants, light dependent reactions occur in the thylakoid membranes of the chloroplasts and use light energy to synthesize ATP and NADPH. The light dependent reaction has two forms; cyclic and non-cyclic reaction. In the non-cyclic reaction, the photons are captured in the light-harvesting antenna complexes of photosystem II by chlorophyll and other accessory pigments (see diagram at right). When a chlorophyll molecule at the core of the photosystem II reaction center obtains sufficient excitation energy from the adjacent antenna pigments, an electron is transferred to the primary electron-acceptor molecule, Pheophytin, through a process called Photoinduced charge separation. These electrons are shuttled through an electron transport chain, the so called Z-scheme shown in the diagram, that initially functions to generate a chemiosmotic potential across the membrane. An ATP synthase enzyme uses the chemiosmotic potential to make ATP during photophosphorylation while NADPH is a product of the terminal redox reaction in the Z-scheme. The electron enters the Photosystem I molecule. The electron is emitted due to the light absorbed by the photosystem. A second electron carrier accepts the electron, which again is passed down lowering energies of electron acceptors. The energy created by the electron acceptors is used to move hydrogen ions across the thylakoid membrane into the lumen. The electron is used to reduce the co-enzyme NADH, which has functions in the light-independent reaction. The cyclic reaction is similar to that of the non-cyclic, but differs in the form that it only generates ATP and no reduced NADP (NADPH) is created. The cyclic reaction takes place only at photosystem I. Once the electron is displaced from the photosystem, the electron is passed down the electron acceptor molecules and returns back to photosystem I, from where si was emitted; hence the name cyclic reaction.\n\nWater photolysis---\nThe NADPH is the main reducing agent in chloroplasts, providing a source of energetic electrons to other reactions. Its production leaves chlorophyll with a deficit of electrons (oxidized), which must be obtained from some other reducing agent. The excited electrons lost from chlorophyll in photosystem I are replaced from the electron transport chain by plastocyanin. However, since photosystem II includes the first steps of the Z-scheme, an external source of electrons is required to reduce its oxidized chlor

Water \n\nPhotosynthesis uses the energy of light to make the sugar, glucose. A simple general equation for photosynthesis follows.\n\n6 CO2 + 12 H2O + light → C6H12O6 + 6 O2 + 6 H2O\nCarbon Dioxide + Water + Light energy → Glucose + Oxygen + Water

The chloroplast -- it's called photosynthesis.

Photosynthesis is important to animals because they receive their energy from its products.  \n\nPhotosynthesis uses energy from the sun to convert CO2 & H2O into glucose and O2 & H2O.  Animals then eat the plants to combine the glucose with the O2 to make energy (ATP), H2O and CO2.  Even the animals that don't consume plants eat other animals that do and indirectly receive nutrition from the byproducts of photosynthesis.  Also, they all breathe oxygen created by photosynthetic organisms.

synthesis means "combining" or "bringing together"\n\nLight is energy - it provides the energy that plants need to change the chemical bonds of the chemical molecules that are present in leaves into the sugars that the plant uses (and people use) for energy.  Chlorophyll takes the CO2 out of the air and combines it with water to make glucose.  Chlorophyll also contains other molecules and elements, which is why plants are so healthy to eat.\n\nThe chemical formula for chlorophyll is:\nC55H72MgN4O5

"The raw materials of photosynthesis, water and carbon dioxide, enter the cells of the leaf, and the products of photosynthesis, sugar and oxygen, leave the leaf."\n\nAnswer:  Carbon Dioxide

Yes, during photosynthesis, plants and trees take in carbon dioxide and release oxygen into the atmosphere.  For this reason, planting trees is encouraged !

the equations of cellular respiration and photosynthesis are related because they are the converses of each other. cellular respiration is oxygen and glucose equaling carbon dioxide, water and energy. photosynthesis is when energy, water, and carbon dioxide equal oxygen and glucose. photosynthesis needs cellular respiration and cellular respiration needs photosynthesis.

i actually know this one....photosynthesis is a reaction where sunlight enters the plant and the chloroplast turns it into ATP (energy) and food for plant. co2+h2o+light=c6h12o2+o2 is the equation for photosythesis. carbon dioxide+water+light=glucose+oxygen\n\nrespiration is the exact opposite of photosynthesis. well the equation is except we replace ATP with light. ATP is the kind of energy we use. there are two types of respiration. anaerobic and aerobic. anaerobic doesnt have oxygen to happen...which then makes the muscles produce lactic acid which makes us sore when we excersise too much. and bacteria produces ethly alcohol which is the alcohol u drink. aerobic needs oxygen to carry out. and it produces either 36 or 38 ATPs i dont remember. and the more ATP (energy) u have. the better. hope that answered ur question. and im only in the ninth grade..so proud of myself. :)

well photosynthesis is a good way to start. the water from the roots are pulled by cohesion and then it leaves from the stroma in the plant leaves.

Carbon dioxide, because that is the raw material required for photosynthesis

Oxygen is the byproduct of photosynthesis, which means that trees create oxygen by processing sunlight, water, and carbon dioxide into the simple carbohydrates they need as "food."

1. respiration is for animals, and phtosynthesis is for vegetals, bacteria and algae.\n\n2. We (animals) use respiration because our cells need a process called gas exchange ( we take Oxygen from the air and exchange it in our cells for carbon dioxide)\n\n3. This is possible for us because our cells have organs called mitocondria, while vegetal cells have chloroplasts.\n\n4.Photosynthesis is an important biochemical process in which plants, algae, and some bacteria harness the energy of sunlight to produce food. Ultimately, nearly all living things depend on energy produced from photosynthesis for their nourishment, making it vital to life on Earth. It is also responsible for producing the oxygen that makes up a large portion of the Earth's atmosphere. Organisms that produce energy through photosynthesis are called photoautotrophs. Half of all photosynthesis comes not from plants, but from bacteria and algae.\n\nResìration involves the use of developed organs such as lungs.\n\n5. Photosynthesis produces energy from sun light, while\nrespiration produces energy from the Oxygen present in pur atmospheric air.

photosythesis and aerobic cell respiration are REVERSE equations of each other and would probably be described as the TWO most important chemical equations on the planet, (but all equations are important!). Plants are crucial to aerobic life on earth!\n\nPHOTOSYNTHESIS is a synthesis reaction taking small inorganic molecules to make a larger organic molecule (and inorganic byproduct, oxygen. It occurs in the chloroplast of green plants (with chlorophyll pigment) and some photosynthetic bacteria:\n\nEQUATION in words, not formulas: \n\ncarbon dioxide plus water makes glucose sugar (carbs) and oxygen gas (but it needs the sunproper temp, chlorophyll and proper nutirents in the soil to occur\n\nAEROBIC CELL RESPIRATION is a catabolic-decomposition reaction where a larger organic molecule (glucose) is broken down into smaller inorganic molecules (CO2 and H2O) and occurs in the mitochondria of the cell, plant or animal:\n\nEQUATION IN WORDS, not formulas: \n\nglucose (in the presence of oxygen) converts to carbon dioxide, water, ATP (energy molecule) and heat. This is AEROBIC, not anaerobic.\n\nThus plants are able to "take care of themselves." They can make their own glucose from the sun, but then can do cell respiration from glucose they made from photosynthesis. We can't do photosynthesis, so we have to go eat carbs and are thus called heterotrophs.  It's why plants are called autotroph producers.  Anything that eats plants or animals is called a consumer or heterotroph.

Photosynthesis converts carbon from inorganic to organic states.  Then respiration converts carbon from organic to inorganic states.
