What are the different types of passive transport?

1. facilitative diffusion-transport proteins provide a pathway for certain molecules to pass 2. osmosis-the passive transport of water across a selectively permeable membrane 3. diffusion- the net movement of the particles of a substance from where they are more concentrated to where they are less concentrated. (out of a sophomore Biology book)... hope this helps <3


What are three ways molecules can cross the cell membrane?

Molecules can cross the cell membrane through simple diffusion, facilitated diffusion via transporter proteins, and active transport using energy to move molecules against their concentration gradient.


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 are the 2 mechanisms involved when nutrient enter the bloodstream?

The two main mechanisms involved when nutrients enter the bloodstream are passive diffusion and active transport. Passive diffusion allows small molecules to move across the cell membrane from an area of high concentration to low concentration, while active transport requires energy to move molecules against a concentration gradient.


What is the importance of passive and active transport to the cell?

It is passive because it does not require energy when moving molecules. It is passive because it does not require energy when moving molecules. There is both active and passive transport. If it is going against the concentration gradient it is active transport. If it is not acting against the concentration gradient it is passive transport.

What is the meaning of the passive transport?

The inter-membranous transport occurs in two ways: 1) Active Transport: occurs against the concentration gradient, Expenditure of energy occurs. 2) Passive transport: Refers to phenomena wherein transfer occurs along the concentration gradient i.e. from high concentration to low concentration, without any expenditure of energy.

What is the active transport and passive transport?

The requirements of passive transport through the cell membrane (phospholipid bilayer) of an animal cell are that the molecule is non-polar or small enough to pass by the non-polar phospholipid tails. This is because, for there to be passive transport, no energy must be used to transport the molecule from outside of the cell to inside.
