Is the movement of molecules across a membrane down the concentration gradient a passive or active process?

The movement of molecules across a membrane down the concentration gradient is a passive process.


How does the process of diffusion move molecules from a low concentration to a high concentration, and is this movement considered active or passive?

Diffusion is the movement of molecules from an area of high concentration to an area of low concentration. This process does not require energy input and is considered passive transport.


Diffusion is the movement of a substance?

Diffusion is the movement of a substance from an area of high concentration to an area of low concentration, driven by the random motion of molecules. It is a passive process that does not require energy input.


Movement of molecules from high high to low concentration?

This process is called diffusion. Diffusion occurs spontaneously in order to establish equilibrium, where the concentration of molecules is the same throughout a system. This movement is driven by the natural tendency of molecules to move from areas of high concentration to areas of low concentration.


What is the natural tendency of molecules to spread from an area high concentration to an area of low concentration?

Diffusion is the movement of molecules from a high concentration to a low concentration without using ATP (energy). A related term: Osmosis is the movement of water molecules from a high concentration to a low concentration without using ATP (energy). In contrast, active transport is the movement of molecules from a low concentration to a high concentration but DOES use ATP (energy).

What is the movement of sucrose molecules called?

The movement of sucrose molecules is called diffusion, which is the process of molecules spreading out from an area of high concentration to an area of low concentration. This movement occurs until equilibrium is reached.


Diffusion is the process of movement of molecules under a concentration gradient?

Yes


What is the term for the movement of molecules from an area of lower concentration to an area of higher concentration?

If it is the movement of molecules then it is diffusion. If it the movement of water then it is osmosis


What is the process of molecules from an area of high concentration to low?

Diffusion describes the spread of molecules through random motion from regions of higher concentration to regions of lower concentration.


What process is the movement of molecules down a concentration gradient until equilibrium is reached?

The movement of molecules down a concentration gradient until equilibrium is reached is called diffusion. This process occurs when molecules naturally move from an area of higher concentration to an area of lower concentration, driven by their kinetic energy. Diffusion continues until the concentration of molecules is uniform throughout the space, achieving equilibrium where there is no net movement of molecules in any direction.
