What is a passive process in diffusion?
Diffusion. Diffusion is a passive process of transport. A single substance tends to move from an area of high concentration to an area of low concentration until the concentration is equal across the space.

Diffusion. Diffusion is a passive process of transport. A single substance tends to move from an area of high concentration to an area of low concentration until the concentration is equal across the space.

Furthermore, what is the process of passive transport?Passive transport is a naturally occurring phenomenon and does not require the cell to expend energy to accomplish the movement. In passive transport, substances move from an area of higher concentration to an area of lower concentration in a process called diffusion.Secondly, is oxygen diffusion a passive process? Facilitated diffusion. Some molecules, such as carbon dioxide and oxygen, can diffuse across the plasma membrane directly, but others need help to cross its hydrophobic core. A concentration gradient exists for these molecules, so they have the potential to diffuse into (or out of) the cell by moving down it. Also question is, what is diffusion active or passive? While active transport requires energy and work, passive transport does not. There are several different types of this easy movement of molecules. It could be as simple as molecules moving freely such as osmosis or diffusion. Sometimes, proteins are used to help move molecules more quickly.Which process provides the energy for passive diffusion?In active processes the cell provides the metabolic energy (ATP) that drives the transport process to move the substance across the membrane. Diffusion is the tendency of molecules or ions to scatter evenly throughout the environment. Molecules are said to diffuse along or down their concentration gradient.
