What are the differences between sodium-potassium exchange pump and sodium-glucose transporter? Besides I am struggling with understanding the Vesicular Transport (Bulk transport) why it is a form of an active transport? Simple diffusion, facilitated diffusion and osmosis are all passive transport. What are the differences between them and how can be an active form??? And why not concentration gradient is not involving??? Because it utilise transport proteins like receptor mediator endocytosis. It might changes some gradients. Am I misleading some concepts??? Endocytosis and Exocytosis concepts are confusing too. Thanks for reading my question :D I am really confusing of the membrane transport

What is a main difference between active and passive transport? active transport is spontaneous active transport requires an energy input (ATP) passive transport can move molecules against their concentration gradient active transport uses a protein while passive transport does not
In Chapters 11 & 12, the following examples of membrane transport proteins are given. Fill out the table with the correct answer for that particular transport protein. Type of transport protein (channel or carrier/transporter?) K* leak channel glucose transporter bacteriorhodopsin Na-K pump glucose-Na symport Na-H exchanger Performs active or passive transport? Energy source for movement of solute(s) or ion(s) Direction of movement of solute(s) or ion(s) with respect to the electrochemical gradient Na K* Na glucose Na H' Direction of movement of solute(s) or ion(s) with respect to the membrane crossed Na K₁ Na' glucose Na H' Is the protein a uniport, symport, antiport, or none of the above?
How is active transport different from simple diffusion? Both active transport and simple diffusion transport molecules against the concentration gradient. In active transport, molecules are moved down the concentration gradient; on the B contrary, molecules to be transported in simple diffusion are moved against the concentration gradient. In active transport, molecules are transported with the aid of transport proteins; on the © other hand, molecules to be transported in simple diffusion do not need transport proteins. In active transport, molecules that are transported does not need metabolic energy; in contrast, molecules transported in simple diffusion need metabolic energy.
So I know that Dapagliflozin is a inhibitor of the sodium glucose cotransporter so does Dapagliflozin cause glucose to just stay in the cell or does it cause glucose to exit the cell? Also if does cause glucose to exit the cell is this a passive or active process. I would think that it would be passive since the glucose is going from high to low?? So is it faciliated passive diffusion?? Please help I am not sure if I am on the right track or not I could be totally wrong so please correct me.

What is another way to answer this question Describe various examples of active transport. How is active transport different from passive transport? Without saying this: Active transport is when cells move against the flow/ concentration gradient, moving from low concentrations to high concentrations. Because of this, active transport requires ATP to work. Passive transport is different because it doesn't use much energy and moves from high concentration to a low concentration. Some examples of active transport are the Sodium-potassium pump ( the most well known one) where it takes sodium ions and pumps them outside of the membrane to let in potassium ions. Another one in plants is when a plant receives ions from the soil. The soil has a much lower concentration of ions than a plants root does, so ions have to move against the concentration gradient. Endocytosis and exocytosis are also forms of active transport. Where cells engulf its self around large molecules to bring…
Diffusion and osmosis classification Classify the following characteristics based on whether they are describing diffusion, osmosis, or both. Diffusion Results in an Can occur with equal distribution of solute molecules or without a membrane Always involves the movement of water Requires a semi-permeable membrane Osmosis Involves the movement of gases, ions, and small water soluble molecules Passive form of movement that requires no energy Moves from areas of high concentration to low Both Diffusion and Osmosis Responsible for gas exchange in the lungs concentration A 3 of 15 Next > Cation to open the document "Epicinstaller-13.0.0-fortnite-a8e4f12cada646caa706d8be407be69f (3).msi". tv 22
Which of the following statements is correct about passive facilitated diffusion? (select all that apply) V It is a process in which molecules move from a region of lower concentration to one of higher concentration (or up a concentration gradient). O It requires a transport protein. O It requires an expenditure of energy by the cell. O It is a process in which molecules move from a region of higher concentration to a region of lower concentration (or down a concentration gradient). O It involves movement of molecules up a concentration gradient and requires a transport protein.
