concentration gradient.
Passive transport is a process in cells where substances move across the cell membrane without requiring energy input. An example of passive transport is the movement of oxygen and carbon dioxide across the cell membrane through simple diffusion.
Water is transported by a passive transport called osmosis. Osmosis is diffusion of water across the membrane.
It's called passive transport for a cell's membrane. (I checked with my science teacher)
Facilitated diffusion is a type of passive transport that requires special carrier proteins to help molecules move across the cell membrane. These carrier proteins assist in the movement of specific molecules that cannot cross the membrane on their own.
No, primary transport involves the active movement of ions or molecules across a membrane against their concentration gradient, using energy typically derived from ATP. In contrast, the passive movement of large particles across the membrane is known as facilitated diffusion, which does not require energy and occurs through specific transport proteins. Thus, primary transport is an active process, while passive movement relies on concentration gradients.
No, passive transport does not require ATP for the movement of molecules across the cell membrane.

Carrier proteins facilitate passive transport of molecules across a membrane by changing its shape, by using ATP, to allow a substance to pass through the membrane.
concentration gradient
Passive transport refers to the movement of molecules across a cell membrane. An example of a sentence would be: "Passive transport does not require energy to work".
Active transport is ATP dependent, whereas passive transport uses only the kinetic energy of the particles for movement across the plasma membrane- mastering A and P homework-
"Passive" mean that it does not require energy, therefore the passive transport of material across the membrane means that it can transport the material (cells or whatever) without the function of energy across the membrane.
Passive transport.
Active Transport is the passage of materials across the membrane through the expenditure of energy. Passive Transport is the passage of materials across the membrane without the expenditure of energy. Bulk Transport is the type of active transport. Diffusion and Osmosis are type of passive transport.
Water is transported by a passive transport called osmosis. Osmosis is diffusion of water across the membrane.
The rate of passive transport is regulated by factors such as the concentration gradient of the solute across the membrane, the surface area available for transport, the permeability of the membrane to the solute, and the temperature of the system. These factors affect the movement of molecules across the membrane without the use of energy.
Carrier proteins facilitate the passive transport of molecules across a membrane by binding to specific molecules on one side of the membrane and changing shape to transport the molecules across to the other side. This process does not require energy and is driven by the concentration gradient of the molecules.
