Explain facilitated diffusion of glucose using different glucose concentrations & different numbers of glucose
84687
Facilitated diffusion can be thought as regular diffusion with something helping it.  Glucose is too big to fit through the cell membrane so it must be helped across the cell membrance via a channel or transport protein.  It is still considered diffusion because it requires no net energy expended by the cell for the glocose to more into the cell.  This is because molecules are in constant motion which makes them naturally want to spread out.  They want to move from a hight concentration(a large number per given volume) to a low concentration.  For instance perfum moving through a room is diffusion.  In the bottel the perfum is at a high concentration but when you spray it you increase the volume it is in therefor the perfum molecules will move and spread apart.  In a cell the concentration of glucose outside the cell is higher than inside so therefor the glucose wants to move in.  It just needs some help because it is too big to move throught the tiny holes in the membrane.  Its like opening two doors to a building to allow a big cart of material through.  Hope this helps!

I think you can extract glucose from a saturated solution by lowing the solution temperature. The excess solute will crystallize from the solution at the lower temperature. You can filter the mixture to collect the crystallize glucose.\n\nor\n\n You can use the procedure for making rock candy from a sugar and water solution. To extract the glucose from the solution.

if the glucose concentration (and osmotic level) is too high, the microorganism that does the respiration cannot exist or metabolize. like a concentrated syrup or honey. it is simply too concentrated to allow microbial growth, get it?

Substances could move across the cell membrane by either passive or active transport. Passive transport happens with kinetic energy and along a concentration gradient (difference in concentration of a substance).Passive transport includes diffusion, osmosis and facilitated diffusion. Oxygen and carbon dioxide are examples of substances that diffuse.Water will go through by osmosis and glucose is a substance that uses facilitated diffusion.\nActive transport needs energy in the form of ATP and happens against a concentration gradient. Active transport includes endocytosis and exocytosis.It involves the passage in or out of larger molecules.

maltose it is glucose+glucose

movement of molecules is primarily the only similarity. With active transport molecules move from an area of lesser concentration to an area of greater concentration, this requires energy.  Diffusion is also the movement of molecules but they move from an area of grater concentration to an area of lesser concentration; occurs because molecules have free energy, like the diffusion of o2 &co2 in the lungs

Given that a certain type of molecule is small enough to permeate through the cell membrane, the most important factor influencing the rate of diffusion is the concentration gradient.  This is simply the difference in concentration levels of the substance between the outside and the inside of the cell.  The larger the difference in concentrations, the greater the rate of diffusion.

Seems that many factors can vary how much glucose can be in a potato.\n\nPlease see the attached link for a detailed article that is sure to more than answer all your questions concerning glucose in potato's.\n\n\n\nhttp://www.findarticles.com/p/articles/mi_qa4069/is_200409/ai_n9443290

The solute CaBr2 contains 3 ions, which are all separated when it dissolves in water.\nGlucose, although it is a big molecule, is only one particle. Therefore CaBr2 provides three times the lowering of freezing point that glucose does\nBoth substances are freely soluble because the particles have a good attraction to water. But the solution of CaBr2 will not freeze at -5C because it has 6.00M of ions in it (3 x 2.0M).

The transport will be proportional to the concentration.  Higher concentration faster extraction.

Ideally, if the glucose bag is permeable to glucose (i.e. glucose can diffuse in and out of the bag), then water can also do the same - remember that water is much smaller than glucose.  What you'll end up with is a very diluted glucose in your entire beaker and bag; so yes, they will reach equilibrium.\n\nThe second beaker, with the protein, is ambiguous.  You say that the protein cannot diffuse through the bag, but we are not aware if the water is able to do so itself.  If the water can diffuse in and out of the bag, then the bag will expand until it bursts.

The combustion of glucose is as follows:\n\nC6H12O6 + 6O2 --> 6CO2 + 6H2O\n\nSo, the mole ratio is 1 mol glucose per 6 mols O2.

Most solutes (sugar in this case) have limited solubility (ability to dissolve) in most solvents (water in this case). This solubility varies with temperature - the hotter the solution, the higher the solubility. As mentioned in an earlier answer, this means more energy must be added to dissolve more solute. On the other hand, if energy is taken out of a solution, the solute will usually  come out of the solution, depending on the concentration.\n\nThis physical law that governs this is the 2nd law of thermodyamics.
