Why Leaves Change Color
http://na.fs.fed.us/fhp/pubs/leaves/leaves.shtm Competition: low
Where can I see autumn color in the United States? You can find autumn color in parks and woodlands, in the cities, countryside, and mountains - anywhere you find deciduous broadleaved trees, the ones that drop their leaves in the autumn. New England is rightly famous for the spectacular autumn colors painted on the trees of its mountains and countryside, but the Adirondack, Appalachian, Smoky, and Rocky Mountains are also clad with colorful displays

Some fires are set by humans by accident or for agricultural purposes, but many are natural phenomena caused by the right combination of dry timber, hot weather and lightning. Plants could not produce these molecules without carbon dioxide, and they could not absorb carbon dioxide from the air without the help of specialized cells on and within their leaves

This ATP is used in conjunction with the NADPH made by photosynthesis to drive a large number of biosynthetic reactions in the chloroplast stroma, including the all-important carbon-fixation cycle, which creates carbohydrate from CO2. There are many intermediates between glyceraldehyde 3-phosphate and ribulose 5-phosphate, but (more...)A total of 3 molecules of ATP and 2 molecules of NADPH are consumed for each CO2 molecule converted into carbohydrate

Even though these pigments absorb light at shorter wave lengths, the photons are transferred to the active centers which have an absorption spectrum at longer wave lengths. Blackman, Calvin, Arnon, Emerson, Park, Sanpeitro, Govindjee, Ellis, Parker, are the notables among the stalwarts who have made significant contributions in understanding the structure and functional aspects of Photosynthesis

These high-energy electrons will be used in the Calvin Cycle to reduce CO2 to make sugars The H+ is pumped into the thylakoid membrane to generate an H+ gradient (i.e. Each arrow in the diagram above actually represents a reaction like this one: Each element in the pathway is reduced by the electrons, and turns right around to reduce its neighbor in the pathway by giving it the electrons, thus becoming reoxidized and ready for the next electrons to pass through the photosystem H+ Pumping

Every time you eat meat, you are taking food out of the mouths of 9 other people, who could be fed with the plant material that was fed to the animal you are eating. This community may serve as an exchange pool (although for some chemicals like carbon, bound in a sequoia for a thousand years, it may seem more like a reservoir), and also serve to move chemicals from one stage of the cycle to another

Each of these cultures can be subjected to a different drug, thus enabling doctors to find the right drug sooner, while it may still be of help, and without needlessly subjecting the person to many kinds of toxic chemicals. The nuclear envelope has totally disintegrated and the polar fibers have reached the centromeres of the chromosomes and have begun interacting with them

This modification allows for a greater amount of carbon dioxide to be converted to carbohydrate during the day than would be otherwise converted given the conditions CAM plants generally grow in. After a photon of light strikes a P700 molecule, the resulting excited electron is passed along to an iron-sulphur molecule Fe-S which in turn passes it to another acceptor molecule ferrodoxin, (Fd)

They are light dependent in that they need the energy given off by the sun to "excite" the electrons in order to move down the electron transfer chain, which ultimately prepares them to be used by NADP+ to form NADPH to assist in the light independent cycle.

A new nuclear membrane, using the membrane vesicles of the parent cell's old nuclear membrane, forms around each set of separated daughter chromosomes (though the membrane does not enclose the centrosomes) The nucleoli reappear, too.

The capture of carbon dioxide by PEP is mediated by the enzyme PEP carboxylase, which has a stronger affinity for carbon dioxide than does RuBP carboxylase When carbon dioxide levels decline below the threshold for RuBP carboxylase, RuBP is catalyzed with oxygen instead of carbon dioxide. Many Prokaryotes have only one photosystem, Photosystem II (so numbered because, while it was most likely the first to evolve, it was the second one discovered)

The oxaloacetate is converted to other 4-carbon intermediates that are transported to cells active in photosynthesis, where CO2 is released by decarboxylation.

In C3 plants, CO2 is fixed to RuBP to form a 6 carbon compound by the enzyme rubisco.When the concentration of CO2 is low, oxygen will bind to the active site of rubisco.

So the only real difference between C3 and C4 photosynthesis is that between the light-dependent and Calvin-Benson cycle, there is an additional step where carbon is transported to the interior of the leaf. When the sun (and the temperature) rises, the plants close their stomata to conserve water and begin using the carbon stored in their vacuoles in the Calvin-Benson cycle
Calvin Cycle

So while the "traditional" product of photosynthesis is a sugar, we have to keep in mind that a sugar is a versatile material in the biochemical context of a plant cell! More of that below.

Some of this G3P is used to regenerate the RuBP to continue the cycle, but some is available for molecular synthesis and is used to make fructose diphosphate.
