Since this is electolysis.... Find a table of the standard reduction potentials, if you're in a general chem class or something there should be one in the back of your book. The more positive your standard reduction is for a particular reaction, the stronger of an oxidizing agent or oxidant it is. The more negative the standard reduction the stronger it is as a reducing agent or reductant. If you have two cations in solution at the cathode the one being reduced is the strongest oxidant or the one with the more positive standard reduction. The reverse is true at the anode. So the key is FIND A TABLE OF STANDARD REDUCTION POTENTIALS

As a Libertarian I view any form of income tax as robbery. We need to move to a national sales tax that excludes the essentials like food and clothing. If return the government to its original purpose there would be little need of the trillions of dollars the US government uses.

Pah, I have a several hundred dollars worth of biology textbooks and other reading just laying around my desk. With all the frickin money that I've spent why would I use google?

Your posts make me think of you as "VERY" energetic person. I imagine your practically bouncing off the walls. If you really do chew coca leaves that would explain a lot.

yep, I especially like: http://img.photobucket.com/albums/v222/beamin/me1.jpg

Good enough

exactly why I stick to meat, keeps ya young.

This explains a lot.......

budullewraagh: You look pretty old for being the same age as my younger sister.....

I like the long lasting effects of caffeine, helps in the wee hours of the morning when I finally decide to study for my quantitative analysis test thats only few hours away. damn I hate quant...

It does both, and theres also a 3rd method, cant remember it though.

Actually I think it was visking tubing that we used. Isnt cellophane tape impermeable to air?

http://www.forbes.com/newsletter/2004/11/01/cz_sg_1101soapbox.html From 1994 to 2004 its been about $300 million total.

Could this be it? http://www.aip.org/pnu/2003/split/648-1.html Or maybe your thinking of some hydrogen isotopes like deuterium and tritium, in which case the mass would be more.

Semi-permeable means that there are openings small enough for the water molecules to cross, but not larger substances like carbohydrates. A blown up version wouldnt be semipermeable because other substances go pass through. There are semi-permeable materials out there, cant think of any off the top of my head. We used some sort of material in a Biol lab once to demonstrate the concept but its been to long to remember what it was. No, a sponge has pores that allow water to be retained, but its not a semi-permeable material.

Plants dont move? Yes they do, many plants are capable of reacting to stimuli within seconds. Leaves regularly move in relation to the sun. Probably the most dramatic examples of plant movements is the venus fly trap. Cell walls may be more rigid than cell membranes, but dont take that to mean that its immobile. The cell wall is actually quite elastic.

Ahh, I dont have any pictures of me on my computer, otherwise maybe...... DandyGurl: All I have to say is, if thats you then, DAMN!

Im addicted to caffeine.

The reason you may end up with only 36 or so is that 2 ATP can be lost in transporting pyruvate. Im going to nitpick. Respiration includes fermantation. Fermantation is involved with Anearobic respiration. In aerobic respiration (what you're thinking of) there are two processes going on. The first is called the Krebs Cycle, the second is oxidative phosphorylation, more commonly known as the electron transport chain.

Endosymbiosis, the theory that says that plastids such as mitochondria and chloraplasts are actually the decendents of bacteria that entered into a symbiotic relationship with other cells. Several weeks ago my plant physiology professor made an interesting prediction. The roots of legumes form symbiotic relationships with nitrogen fixing bacteria calle rhizobium. The process of how the root cells and rhizobium actually form their relationship requires that the bacteria infect the root cells. The prediction made by my professor was the possibility of these bacteria one day becoming just as much a part of the plant as mitochondria. So what we have is a possible case for future endosymbiosis. What do you guys think? For more information on the process of how rhizobium and legumes interact go here: http://www.ls.huji.ac.il/~nurit/photosyn/Nitrogen/Rhizobium-legumeassociation.htm

38 ATP is the maximum yield possible and so is only an estimate.

4 ATP are produced by glycolysis, but glycolysis requires an input of 2 ATP so your net increase is only 2ATP. The process als produces 2 NADH, which are later used in the oxidative phosphorylation to form ATP. A total of 2 ATP are produced. The Krebs cycle produces 6NADH and 2 FADH2 which are then used in oxidative phosphorylation to produce ATP. Those 8 NADH and 2 FADH2 are then used in oxidative phosphorylation to produce around 34 ATP for a grand total of 38 ATP. However ATP is also used in various processes like tranporting molecules, so your net yield of ATP is usually lower, more like 36 or something. You have a gross of 4 and a net of 2 ATP from glycolysis. Fermentation doesnt produce any ATP so you only get a total of 2 ATP from the entire process. The reason fermentation occurs is that in order for glyclysis to work you need NAD+ which is reduced to NADH during glycolysis. Fermentation replenshises the supply of NAD+ so that glycolysis can continue.

Absolutely beautiful!

Be careful, I know a lot of places monitor the amount of certain household chems that people buy. If you buy to much they may think your cooking up some meth.

Osmosis isnt that important in the movement of CO2. Think about it. Osmosis is the diffusion of water across a semi-permeable membrane, but we are not concerned about water here, we are concerned about how CO2 is diffused into the cell, not how water moves. That is, as long as we're still talking about Carbon assimilation. And another thing: Not true. Ribulose Biphophate (RuBP), the molecule that reacts with CO2, also reacts with O2. Since O2 enters the stomata with CO2 it is also reacts with RuBP and gets assimilated into the plant cell. I think the ratio is somewhere around 1-3 for O2-CO2.
