Well, the materials pass through go in one end, and the ion channels open and let them pass through, but only with solutes

A type of transport in which water moves across a membrane and down its concentration gradient is?
"Active Transport" is the answer given but if it is the passive movement then no energy is required so isn't it facilitated diffusion?
What transport protein allows ions to pass through the cell membrane?
Ion Channels allows ions to pass through the cell membrane.
In the membrane of a cell channels serve as what?
In the membrane of a cell, channels serve as passageways.
What are examples of diffusion in the human body?
Diffusion occurs in the human body in a variety of ways. Examples of diffusion are through respiration, ion movement and the diffusion of nutrients in the kidney and small intestine.
What is a gated channel?
It is a channel through a membrane that can be opened or closed by chemical or electrical events.
Is diffusion through ion channels a form of active transport?
Facilitated diffusion, or diffusion through ion channels, is not a form of active transport. It is a spontaneous passive transport.
How is facilitated diffusion similar to diffusion ion channels?
They are both types of passsive transportation.
Is facilitated diffusion ion channels an active or passive transport?
passive
Why do you think movement of ions through ion channels is generally a slower process that diffusion?
Let's take something obvious. Where would a crowd of persons move faster? Where there is absolutely nothing to prevent their passage or where there is an open gate? The same thing applies to the movement of ions. Movement of ions through ion channels is a slower process because (with a more scientific approach!) their movement is determined by the number of these ion channels whereas for diffusion, there is absolutely nothing to prevent the passage of the molecules.

Can any ion pass through the ion channels?
yes it can
What transport protein allows ions to pass through the cell membrane?
Ion Channels allows ions to pass through the cell membrane.
How does sodium ion molecule move into the cell through cell membrane?
Through diffusion.
A calcium ion channel will allow?
Only calcium ion channels to pass through it.
In the membrane of a cell channels serve as what?
In the membrane of a cell, channels serve as passageways.
What is the physical mechanism leading to the electrical impulse action potential in an axon?
It is called depolarization and happens when sodium and/or calcium ions enter the cell rapidly through their respective voltage-dependent ion channels or potassium ions stop leaving the cell through their ion channels or chloride ions stop entering the cell through their ion channels.
