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 molecules across a membrane against their concentration at the expense of ATP energy called?
This process is called active transport.
What proceeds against a concentration gradient?
Molecules can move against concentration gradient by a movement called active transport. Molecules move from an area of low concentration to an area of high concentration by using chemical energy called ATP or an electrochemical gradient--either way, it uses cellular energy.
What is the difference between diffusion and active transport?
Diffusion is the movement of molecules from areas of high concentration to areas of low concentration and active transport is the movement of molecules from an area of low concentration to an area of high concentration
What is active transport and passive transport?
active transport requires the use of energy aka ATP and is usually against the concentration gradient. passive transport does not require energy because it moves in response to the concentration gradient.
What is a Diffusion?
Movement of molecules of a substance from its higher concentration towards its lower concentration by their own kinetic energy is called diffusion.

What is A cell moving particles with the use of energy is called?
Active transport: The movement of particles against the concentration gradient into or out of a cell. Bulk transport:The movement of large molecules into or out of the cell. Both of these require energy
If the movement of molecules requires no energy?
it is called passive transport
Is the movement of ions from an area of greater concentration to one of lesser concentration an example of osmosis?
The movement of ions/molecules from an area of greater concentration to an area of lesser concentration is called diffusion.Osmosis is a type of diffusion, which refers specifically to the movement of the solvent (usually water).

What is the difference between diffusion and active transport?
Diffusion is the movement of molecules from areas of high concentration to areas of low concentration and active transport is the movement of molecules from an area of low concentration to an area of high concentration
What is the random movement of molecules and ions down their concentration gradient called?
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.
What does the passive in passive transport mean?
Passive Transport is the movement of molecules down a concentration gradient from a region of high concentration to a region of low concentration until equilibrium is reached. Some examples are diffusion and osmosis. Basically, it's a movement of molecules across a membrane that doesn't require energy (ATP)
What is the transfer of energy by heat caused by the collision of molecules?
When molecules collide and there is a transfer of energy as heat, this is called conduction. When fluids of different temperatures transfer energy by movement, this is called convection.
