Passive transport moves down the concentration gradient, from an area of higher concentration to an area of lower concentration.
facilitated diffusion
Yes, passive transport moves along the concentration gradient, meaning that substances move from an area of higher concentration to an area of lower concentration without the input of energy. Examples of passive transport include diffusion and osmosis.
Transport proteins such as ion channels and carrier proteins are used in both active and passive transport processes. Ion channels move ions down their concentration gradient through passive transport, while carrier proteins can facilitate passive transport by allowing molecules to move along their concentration gradient, or active transport by requiring energy to transport molecules against their concentration gradient.
Yes, movement of a substance down its concentration gradient is considered passive transport because it does not require energy expenditure by the cell. The substance moves from an area of high concentration to an area of low concentration through processes like simple diffusion, facilitated diffusion, or osmosis.
The movement of molecules across a membrane down the concentration gradient is a passive process.
facilitated diffusion
No, constant gradient does not directly relate to passive transport. Passive transport is the movement of molecules across a membrane without the use of cellular energy, while constant gradient refers to a consistent change in concentration over a distance. However, the presence of a constant gradient can facilitate passive transport by driving the movement of molecules down their concentration gradient.

Active transport requires an input of energy and can move substabces against their concentration gradient. Passive transport does not require added energy and can move substances only down their concentration gradient.

ATP (adenosine triphosphate) is used during active transport but not passive transport. Active transport requires energy to move substances against their concentration gradient, while passive transport relies on diffusion to move substances down their concentration gradient without the need for energy.

Cells prefer to use passive transport because it does not require energy input from the cell. Active transport, on the other hand, requires energy in the form of ATP to move molecules against their concentration gradient. Passive transport is more efficient for moving molecules down their concentration gradient.
The random movement of molecules and ions down their concentration gradient (meaning from an area of high concentration to an area of low concentration) is called simple diffusion. Simple diffusion is related to the magnitude of driving force, permeability of the membrane, and surface area.
No. Active transport uses energy to transport specific molecules against a concentration gradient. Passive transport will result in an even distribution of molecules because they allow molecules to move down a concentration gradient.
