What does active transport look like?
The only different between passive and active transport is the use of energy. In passive transport, molecules can either diffuse across the membrane, go through an aquaporin or use a passive transporter. In active transport, energy needs to be released, and it is usually because you are trying to transport a molecule or ion up its concentration gradient.
Is osmosis an active transport?
It is a type of passive diffusion, as the water travels along a concentration gradiant. As opposed to active transport, where the substances can pass against a concentration gradiant.
What is it called when particles travel from an area of high concentration to an aera of low concentration?
Through passive transport
Is Na K pump active or passive?
In biology, an ion transporter, also called an ion pump, is a transmembrane protein that moves ions across a plasma membrane against their concentration gradient, in contrast to ion channels, where ions go through passive transport.
How does active trasport differ from passive trasport?
active transport is when cells must move materials in an opposite direction against concentration gradient. it requires energy. passive doesn't require energy. like a balloon , when u blow it up it requires energy and when u left the air go out it doesn't.
What is the difference between active and passive cellular transport?
Active transport requires energy; passive transport does not.
Osmosis is what type of transport?
Diffusion. It's the movement of water through a permeable membrane. And it's always passive.
How does the concentration gradient affect osmosis?
Osmosis is a passive transport process. Therefore it can only go with the concentration gradient.
What is the function of passive transport?
For molecular substances the cell needs such as glucose or proteins to enter the cell.
How are active transport and passive transport different from each other?
The most basic difference between active and passive transport is that active requires energy while passive does not. You would require active transport if the substance is going against the concentration of molecules inside and outside of the membrane or if the substance is particularly large. Passive is more for smaller molecules that go with the concentration of the molecules inside and outside of the membrane.
Seven word that has to do with transport that does not require energy?
I'm going to go with osmosis, which is the passive transport of water across a membrane from higher to lower concentration.

Passive is more for smaller molecules that go with the concentration of the molecules inside and outside of the membrane.
Why is energy needed for transport?
Molecules are moving against a 'concentration' gradient. Active transportation moving from low to high concentration, while passive transportation such as osmosis and diffusion go from high to low concentration.
Why do you call diffusion and osmosis passive transport?
Simply, it is the opposite of active transport. It does not "spend" chemical energy. Since passive transport is diffusion, molecules will move from higher areas of concentrations to lowers areas of concentrations and no outside force is needed (unlike active transport).
Is oxygen a passive transport or an active transport?
They move via passive transport. They move by diffusion. It's only active transport if A) the cell is too big or not fatty enough to move through the membrane and needs help or B) is making the molecules move unnaturally (low to high). Osmosis is also passive transport, but only is used when referring to the movement of water.
