How do cells transport molecules across a cell membrane?
Molecules can move through the membrane in many ways. If the molecule is hydrophobic (or lipophilic) it can easily pass through the membrane. Other than that, most molecules move through the membrane through channels (which flow towards the molecules concentration gradient) or pumps (which flow against a molecules concentration gradient using energy).
How do you get passed ice tunnel in Snow Line?
Go into the tunnel then go to the flag.
When did Summit Tunnel fire happen?
Summit Tunnel fire happened in 1984.
When It Comes To Facilitated Diffusion What Is The Difference Between Ion Channels?
Solutes are not necessarily ions. Solute transporters and ion channels involve the moving of ions across a cellular membrane. Both a transporter and a channel have the same purpose, but different functions. Ion channels are proteins that open a pore often in the presence of a ligand, or a binding partner, that allows for a free flow of ions through its gap. A transporter is defined much the same, but involves an occluded state, or a state in which the ion is trapped within the protein, and must wait for either side of the protein to open before it can escape. Technically, the difference between a transporter and an ion channel is very ambiguous as both seem to use very similar pathways. However, for clarity sake, channels are proteins which open a clear tunnel for passage. While transporters utilize stepwise changes in protein conformation which trap the ion and then allow it to move down to the other side of the membrane.
What is the tunnel that lava travels to reach the top of the volcano called?
The "tunnel" that magma travels through is called a vent.
How do molecules that are too large to cross the membrance enter into the cell?
If the large molecule won't pass through the membrane by diffusion, it might be dragged through the membrane by "endocytosis".
Does a GRE tunnel allow the use of dynamic routing protocols across the tunnel?
Yes
What is the bridge for by the giant chasm?
so you can go across the tunnel
How do substances like carbon dioxide and water moves in and out of the cell?
Carbon dioxide is a small nonpolar molecule which means that it can easily diffuse through the lipid bilayer of the cell membrane. Carbon dioxide moves from an area of high concentration to an area of low concentration. Diffusion is passive transport (no ATP required). Water is a polar molecule but it is pretty small so it can still dissolve through the lipid bilayer into the cell. The movement of water from an area of lower solute concentration to an area of higher solute concentration across a semipermeable membrane is called osmosis. Aquaporins are small water channels embedded in the lipid bilayer. These protein water channels provide a hydrophilic (polar) tunnel through the lipid bilayer for the fast movement of water across the membrane.. Aquaporins are a form of facilitated diffusion (diffusion with "help"). Osmosis and facilitated diffusion are forms of passive transport.
What is the Euro tunnel?
The Euro tunnel is a like a train which carries transport across the English Channel connecting Britain and France. Sometimes the euro tunnel is called the CHunnel because it is a tunnel going through a channel so....chunnel!
Poptrapica help how do you get across 24 Carrot tunnel?
When you get to the factory and you clim b up, there is a window when your on the roof there is a map of the tunnel youse the map to guide you.
Is there a bridge or tunnel across Cook Strait NZ?
no but it has been under discussion for years
What is found in buckyballs?
Carbon Yes and technology exists to insert compounds inside the tunnel. This is a key area of research for superconductors.

How do you get to Italy from England without flying?
By ferry or channel tunnel across to France and then by road or rail to Italy.
What does Transmountain means?
The word transmountain means that something goes across a mountain. An example would be a tunnel that goes through a mountain, or a bridge that goes across a mountain.
What is an example of a channel protein?
Channel proteins are integral proteins (also transmembrane proteins) which has pores that allow passage of water and hydrophilic solutes through the cell membrane.some are open while others are gates that can be open or close in respond to different stimuli:1. Ligand gate---> in respond to chemical2. Voltage gate---> in respond ot electrical potential across the plasma membrane3. Mechanical gate--> in respond to physical stress on a cell (strech,pressure)
