How does the human impact fit into the phosphate cycle?

Humans affect the phosphorus cycle when farmers put fertilizers with phosphorus in them on their fields.

As Beare85 said, the matter comes in as nutrients or food. Metabolism consists a series of reactions that happens in the body and in cells, taking in food (potato, beef and so on), brakes them down into the smallest biological molecules (particles such as proteins, carbohydrates, fat, and other minerals and vita mines, while storing the energy of those bonds), then uses them as building blocks for their functions. In the body, a lot of the breaking down happens in the digestive system, and is spread through the body in the blood. Cells absorb nitriente mostly as building blocks already. Cells are mostly proteins, lipids (fat) and water. It all comes from food.

The Urea (or the Krebs-Hensliet) cycle outlines the mechanism by which ammonia is finally produced in the final reaction (involving Arginine, if I am right)\n\nAmmonia excretion can also be regarded as excretion of Nitrogen from different intermediates in the body. All of these N containing intermediates converge into the TCA cycle from where they become amino acids through enzymes known as deaminases or transminases. These amino acids converge to a common amino acid (alanine in humans, if i recollect well) which then travels to Kidney and initiates the UREA cycle to finally result in the production of Ammonia

The sourcce of energy for anybody to move, think, or perform any kind of action- whether it is physical or even thinking is the wonderful molecule called ATP- or , Adenosine TriPhosphate. This molecule consists of a base (adenosine) that is attached to a ribose sugar, and three other phosphate groups, hence the name tri-phosphate. Now, when ever the brain detects the intention of motion, or the human preceives that he/she must start moving, as happens in contents or in danger, the brain instructs the body to start breaking down this molecule, ATP, but not completely, only cleaving one phosphate group, so the adenosine triphosphate, is now called adenosine di-phosphate, and a dettached group of phosphate. This cleaving is eesential for body in motion, or brain in thinking since in that link, between the one phosphate group and the rest of the ATP molecule there is a huge energy storage, that can only be "unleashed" if you break that bond. Now, how can you get ATP? this ATP is like your available currency that you use at the grocery store to buy food; but first you must go to the bank and pull out some money. The body does the same thing, only with glucose, starch and fat storage that is dispersed across your body. These storages (bank accounts) start to break down when you start exercising or moving for a long time period thereby producing even more ATP molecules ready to be used by the body. This is the reason why runners tend to drink or ingest really sweet substances since they have a lot of glucose, hence a lot of ATP available. Another reason is, as you exercise more the body starts breaking down the fat storages in the body in order to obtain the necessary amount of ATP to sustain your physical activity, that is why you lose weight when you exercise. I hope it helped. Good Luck.

Most detergents have already reduced phosphate levels to below requested minimums. I think you have a stale worry and need to upgrade your worry list.

In a word: unbalancing. \nNutrient cycles have several stages and are long-term processes. Human action may 1) increase concentration of X nutrient by pollution, fertilization, etc, or 2) decrease concentration of X nutrient by non-sustainable extraction, use and degradation.

Humans have made huge impacts on the physical environment by logging, farming, building, and really just existing. The problem is the rate of change is accelerating as the population grows exponentially and people become industrialised and require more and more. The earth really cannot sustain this growth in all aspects of people greed and need. There is no easy way to slow it let alone stop it.\n\nAs a planet we are doomed! not tomorrow but before this century is out.

It uses up all of the "nutrients" or whatever in the soil.  Crop rotation and planting things like legumes were done to allow the land to recharge between planting cycles.

Sure.  "Studies on the interaction of U(VI) with living cells, spores, heat-killed cells, and decomposed cells of Bacillus sphaericus by time-resolved laser fluorescence spectroscopy show that different phosphate complexes are formed. Using fresh intact cells, the U(VI) is bound to organo-phosphate groups of the bacterial cells. With increasing age of the samples, the cells begin to lyse. During this process, inorganic phosphate is released and a uranyl phosphate precipitate is formed. The characterization of the released phosphate species by Raman spectroscopy and the uranyl phosphate complexes by time-resolved laser-induced fluorescence spectroscopy (TRLFS) has shown that the bacteria release H2PO4- during decomposition which leads to the formation of UO2(H2PO4)2."

Well, it's not easy. Phosphoric acid is H3PO4. Phosphorus is at an oxidation state of +5. If you want it to reduce to plain phosphorus (ox. state of 0), you'll need something to oxidize. If you're not a professional chemist, it'd be much, much, much easier just to buy some phosphorus.

Biological systems have enzymes (and a handful of other reagents) which will use O2 and sugar to make energy--specifically, hexokinase (HK), phosphoglucose isomerase (PGI), phosphofructokinase (PFK), aldolase, triose phosphate isomerase (TIM), glyceraldehyde-3-phosphate dehydrogenase (GAPDH), phosphoglycerate kinase (PGK), phosphoglycerate mutase (PGM), endolase, and pyruvate kinase (PK).  The process undergone is called glycolysis.  The result is that glucose is consumed, making two pyruvate molecules (which in some systems can then enter the Citric Acid Cycle aka Kreb's Cycle) and ADP is turned into ATP, which is an energy source.\n\nAnd after memorizing this and subsequently forgeting all this useless detail some years ago, I nearly ralphed on my book reading this just now.  Bad memories.
