How are active transport and passive transport different from each other?
Wiki User
∙ 13y ago
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.

Compare active transport to passive transport?
Active transport requires energy, whereas passive transport does not. Passive transport is normally something moving from an area of high concentration to low concentration (with the grain). Active transport is something moving from an area of low concentration to an area of high concentration(against the grain).
How does active transport occur?
Active transport requires two main tools. The first one is a protein that captures the particle from one side - of a cell wall for example - into the other side. and the second thing is energy mostly in the type of ATP. so the protein does the job of moving the particle across the membrane by using energy and that is how active transport is different from passive transport. In passive transport the particles simple diffuse from one side of the membrane into the other because of the difference in the substance's concintration between the two sides.
Give two differences between active transport and passive transport?
Active transport requires energy, passive transport just happens. If there is more of a certain molecule on one side of a membrane than the other, molecules that CAN fit through the membrane will do, so the concentration will even itself out. No work has to be done to achieve this. SO when you breathe in, oxygen just diffuses across from the air into your blood, because there's plenty of it in the air. But if a plant needs to get say magnesium from the soil (which it needs to make chlorophyll) then it is not going to get much by diffusion, because there's not much in the soil and probably more in the plant. It will need to use active transport ie a protein in the cell wall will pick up the substance wanted and flip it into the cell, and this costs the cell some energy.

What is the difference between passive and active transport across the cell membrane?
Wouldn't it be that active transport requires enegry and passive doesn't? Passive transport occurs when the concentration of something on one side of membrane is different from the concentration on the other side. It occurs when that substance can pass through the membrane, and always in the direction of more -> less. No energy is required to make the substance move; in fact, this movement generates energy. This is like rolling a rock down a hill--it just does it on its own. Active transport occurs in the opposite direction, from less -> more. It requires energy for transport. This is like rolling a rock up a hill--you have to push it the entire way! Both involve the transport of a substance across a membrane, and the change in concentrations on different sides of a membrane. Both are also important to the proper functioning of a cell. Active transport requires energy, but passive transport requires none. Active transport requires a special protein to make the transport occur, but passive transport requires none.
How is passive transport different then active transport?
An example of passive transport would be the process of osmosis (water diffusing between a membrane-- from an area of high concentration to an area of low concentration). It is known as passive transport because no energy is needed in order to move the water across the membrane. When no energy is needed to move the substance it is considered passive transport. On the other hand, when energy IS needed to transport molecules or substances across a membrane it is referred to as active transport. An example of this would be a calcium pump located in the lipid bilayer of a plasma membrane which can transport potassium (K+) ions across it. Energy is needed in order to move those potassium ions across the membrane, and therefore is referred to as active transport.
What energy is required for passive transport?
By definition, passive transport on a cellular level requires no energy other than some sort of gradient, whether of the molecule in question, or another whose movement across the membrane can be linked to the one of interest.
What is the differece between passive and active transport?
Active transport is the movement of molecules across a membrane requiring energy to be expanded by the cell. ACTIVE TRANSPORT REQUIRES ENERGY. Passive transport is diffusion across a membrane requiring only random motion of molecules with no energy expanded by the cell. PASSIVE TRANSPORT REQUIRES NO ENERGY.

How are active and passive differ from 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.

What is the difference between active transport and passive transport mean?
Passive transport is a form of transport that does not require an input of energy. Examples include diffusion, osmosis and facilitated diffusion. On the other hand, active transport is a form of transport that requires an input of energy in the form of ATP (adenosine triphosphate). This energy is required for processes such as moving molecules against the concentration gradient.
What is a non example of osmosis?
active and passive transport are two... if you are asking for examples of membrane type transport other than osmosis

What are all the differences between active and passive transport?
Passive transport occurs when the concentration of something on one side of membrane is different from the concentration on the other side. It occurs when that substance can pass through the membrane, and always in the direction of more -> less. No energy is required to make the substance move; in fact, this movement generates energy.
