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.


The movement of substances through a cell membrane without the use of cell energy?

Passive transport using osmosis and diffusion. Osmosis only applies to the movement of water down a concentration gradient across a selectively permeable membrane. DOH!!!


Is facilitated diffusion type of active transport?

Facilitated diffusion is passive transport as no energy is used, and a protein channel is all that's required. After that it is simple diffusion down a concentration gradient. Anything with the word diffusion in it is passive transport. Diffusion is just the principle of passive transport.


What isit called when a molecule moves across a semipermeable membrane into a region of higher concentration?

When a molecule moves to a higher concentration it needs help of a pump. We call this facilitated diffusion. Osmosis only deals with the movement of water.


Oxygen and carbon dioxide are exchanged in the lungs and through all call membrane an active transport b diffusion c filtration d osmosis?

Oxygen and carbon dioxide are exchanged in the lungs through diffusion. Oxygen moves from the alveoli into the blood, while carbon dioxide moves from the blood into the alveoli, driven by differences in their concentration gradients. This process does not involve active transport, filtration, or osmosis.

What are five transport mechanism where by metabolites nutrient or ions cross the cell membrane?

There are many forms of membrane and cell transport. These are the basic transport mechanisms in a prokaryotic animal cell. Facilitated Diffusion Osmosis Diffusion Exocytosis (this takes two forms; phagocytosis and pinocytosis depending on whether the cell is "eating" or "drinking") Endocytosis Carrier Molecules/Channel Proteins

What is the movement called when a call does not use energy to move particles across the cells membrane?

It is called passive diffusion.


What is the passage of water through call membranes?

simple answer osmosis defined as the diffusion of water from a area of high concentration to a area of low concentration.


What is the movement of water across a semipermeable membrane from an area of high water concentration to an area of low concentration called?

Osmosis


When wilted salary is soaked in water it becomes crisp again due to what?

Osmosis, which is the diffusion of water through the cell membrane from an area of higher concentration to and area of lower concentration. Hope this helps.
