Small ionsSome previous streaming potential and EMF measurements on human stratum corneum in vitro (J. Control. Release 32 (1994) 249) are explained in terms of a simple physical model based on the intercellular pathway for passive transport of small inorganic ions. These are assumed to diffuse...
Passive transport definition is the movement of ions or particles from an area of high concentration to an area of low concentration. This can be recognized when raisins are put in a bowl of pure water. The raisins will swell as water moves from high concentration (water) to low concentration...
What process brings food into the cells during active transport? What is the means of transport for large molecules and ions? Why is it important for cells to be able to use both active and passive transport to transport molecules across the cell membrane?
Ion Transport can be Active or Passive The definitions of active and passive transport are thermodynamic. Passive transport occurs in the direction expected for the existing driving force, which in the case of ions involves the chemical gradient (given by the difference in concentration between the ...
Diffusion of ions across a membrane depends on what?What are the steps in the process of diffusion and osmosis?Which type of transport requires the most energy use by cells? a. Diffusion b. Passive transport c. Phagocytosis d. None of the above...

Passive:An Passive transport, also known as passive diffusion, is the process by which molecules or ions move across a cell membrane along their concentration gradient, from an area of higher concentration to an area of lower concentration, without the need for cellular energy expenditure. ...
Passive Transport: Passive transfer means the flow of molecules or ions across a semi-permeable membrane without energy input. It is a ubiquitous process in biology. Passive transport can include simple diffusion or facilitated diffusion. Answer and Explanation: ...

People can see passive transport at work outside the body as well as within it. For example, diffusion is commonly used for techniques like making agar plates to research microorganisms. The researcher can deliver antibiotics to one area of the plate and rely on them to diffuse throughout the...
