No, not really. Diffusion works when molecules move from an area of higher concentration to an area of lower concentration. They move independently of one another. So even if you have a high level of NaCl, the glucose concentration will diffuse in the same manner.
The rate of transport of glucose is primarily influenced by the concentration gradient of glucose. A steeper concentration gradient typically results in a faster diffusion rate, as glucose molecules move from an area of higher concentration to one of lower concentration. However, other factors such as temperature, membrane permeability, and the presence of transport proteins also play significant roles in the overall diffusion process. Thus, while the concentration gradient is a key factor, it is not the sole determinant of glucose transport rate.
Facilitated diffusion of glucose through carrier proteins is a passive process where glucose molecules move across the cell membrane with the help of specific carrier proteins. These carrier proteins bind to glucose molecules on one side of the membrane and release them on the other side, allowing glucose to move from an area of high concentration to an area of low concentration without requiring energy input from the cell.
thanks to: Bobama 08. question: what transport supplies a cell with glucose? answer: The passive transport supplies a cell with glucose. A passive transport is the diffusion of particles through the proteins. The particles move from an area of high concentration to an area of low concentration. The cell does not need to use any energy to make this happen. Whereas, an active transport is the movement of particles through proteins against the normal direction of diffusion. Particles are moved from an area of low concentration to an area of high concentration. The cell must use energy to make this happen. This energy comes from the molecule ATP, which stores energy in a form that cells can use. Therefore, the passive cell transport supplies a cell with glucose.
Yes, simple diffusion/passive diffusion is the movement of a particle from an area of high concentration to one of lower concentration.
Are called osmosis
There is no exact number assigned to the difference between the higher and lower concentrations. However, the establishment of a concentration differential is essential for both diffusion as well as osmosis.
Basically Co-transport is the movement of molecules such as Glucose and Amino Acids into the epithelial cells lining the small intestine.This can be quite complicated to learn.In this case we'll look at Glucose :)There are three different protein carriers/channelszperiodzFirstly Sodium ions in the epithelium are taken actively out of the epithelium and into the blood by the sodium-potassium pump.This process is active transport as it uses ATP.This in turn causes the sodium ion concentration to lower.So there is a low concentration of sodium ions in the epithelium but a high concentration in the lumen of the small intestine. Therefore the sodium ions in the lumen can now diffuse down the concentration gradient and into the epithelium, however as they do they couple with Glucose molecules in the lumen and drag them into the epithelium with them.The protein channel used is the co-transport protein.There is now a high concentration of Glucose in the epithelium and a low concentration in the blood, therefore by Facilitated difussion the glucose molecules are taken into the blood :) Hope that helps !!
significantly higher in one area compared to another, leading to a steep difference in concentration levels between the two areas. This gradient allows substances to move from areas of high concentration to areas of low concentration through passive transport processes like diffusion or osmosis.
This is referred to as OSMOSIS. When you say "solution of lower concentration" this implies the solute concentration is low, thus water concentration is high. So, osmosis is movement of water from a high concentration of water, to a lower concentration of water, just to be clear.
Well, isn't that a happy little question! With more glucose on one side and less salt on the other, water will tend to move from the side with lower concentration of solutes (salt) to the side with higher concentration of solutes (glucose) to try to balance things out. This process is called osmosis, and it's nature's way of keeping everything in harmony.
