Simple diffusion goes with a concentration gradient and does not use ATP where active transport uses ATP to go against a concentration gradient.

No it does not..........simple diffusion is nauture


What 3 ways can substances enter and leave a cell?

Substances can move in and out of a cell in several ways. Diffusion is when a substance will distribute itself in or out of a cell until the distribution on both sides of the cell is balanced. Active transport is when a cell transports a substance across the cell membrane that would not normally be able to pass through. Osmosis is the movement of water from areas with few dissolved dissolved substances to areas with high dissolved substances.


Which of these nephron transport processes does not show saturation at high solute values a. coupled cotransport b. facilitated diffusion c. active transport d. simple diffusion?

d. Simple diffusion does not show saturation at high solute values as it is a passive process that is concentration-dependent. The other processes listed can become saturated at high solute values due to limited carrier molecules or transporters available for binding.


Ions diffuse across membranes down their what?

Its an active transport and use sodium channel generally _____ Diffusion is itself a pathway of travel across a cell membrane. Diffusion can be "simple diffusion" which is simply an ion moving across the membrane anywhere, or "fascilitated diffusion", where an ion moves across the membrane in a specific channel. Either way, diffusion involves the movement of that ion along its concentration gradient and requires no energy. Active transport is not the same as diffusion. Active transport requires energy.


What moves products through a cell membrane?

Diffusion, facilitated diffusion, Osmosis and Active Transport. Diffusion moves non-polar molecules across the cell membrane down a concentration gradient. Osmosis moves water across the cell membrane through a channel formed by aquaporins called a protein channel, down the water potential gradient. Active moves the non-polar molecules against the concentration gradient, in contrast to diffusion. Lastly, facilitated diffusion moves polar molecules across the cell membrane through creating protein channels in the cell membrane from specific proteins. ETC, glucose transporters bind to form a protein channel for glucose to diffuse through, after which the proteins disperse. That should be all, hope it was of help!

Passive, it's just a substance moving from higher to lower concentrations.


What are three ways molecules move through a semipermeable membrane?

Three ways molecules move through a semipermeable membrane are simple diffusion, facilitated diffusion, and active transport. In simple diffusion, molecules move from an area of high concentration to low concentration without the need for energy. Facilitated diffusion involves the movement of molecules across the membrane with the help of protein channels or carriers. Active transport requires energy and moves molecules against their concentration gradient.

What process does dialysis use active transport simple diffusion or facilitated diffusion?

If your talking about a high concentration (outside the dialysis bag) to low concentration (inside the dialysis bag), then it's simple diffusion because it does not requires any energy, and not facilitated in any way


What functions might the three types of diffusion serve in a multicellular organism?

Simple diffusion: Allows for the exchange of small, non-polar molecules across cellular membranes, important for nutrient uptake and waste removal. Facilitated diffusion: Facilitates the transport of specific large or charged molecules by utilizing carrier proteins embedded in cellular membranes, crucial for maintaining cellular homeostasis and signaling. Active transport: Uses cellular energy to move molecules against their concentration gradients, enabling the absorption of essential nutrients and the removal of waste products from cells.


What is the defference between active transpors and passive transport?

Active transport requires energy input to move molecules against their concentration gradient, while passive transport moves molecules along their concentration gradient without energy input. Active transport is typically carried out by transport proteins, such as pumps, while passive transport can occur through simple diffusion or facilitated diffusion.
