Facilitated diffusion does not use vesicles; it involves the movement of molecules across a cell membrane through specific transport proteins. This process allows substances, such as glucose or ions, to passively move down their concentration gradient without requiring energy. In contrast, vesicular transport, such as endocytosis or exocytosis, involves the formation of vesicles to move larger substances into or out of the cell.
What else can I help you with?
What is is called when vesicles are used to move substances out of the cell?
The process that requires transport vesicles to transfer material out of a cell is called exocytosis.
Does diffusion require help from vesicles?
No, diffusion does not require help from vesicles. Diffusion is the movement of particles from an area of high concentration to an area of low concentration, driven by concentration gradients. Vesicles, on the other hand, are membrane-bound structures that transport materials within cells through processes like endocytosis and exocytosis.
Is endocytosis an example of diffusion?
Endocytosis is NOT an example of diffusion. It is an example of active transport whereas diffusion is a type of passive transport. The difference lies in the fact that diffusion does not require energy to take place, and endocytosis does.
Are vesicles involved in passive transport explain?
Vesicles are primarily associated with active transport processes, such as endocytosis and exocytosis, where they facilitate the movement of substances across cell membranes against their concentration gradients. Passive transport, on the other hand, involves the movement of molecules down their concentration gradients without the need for energy, typically through diffusion or facilitated diffusion. While vesicles are not directly involved in passive transport, they can transport substances that may ultimately diffuse passively once inside the cell or released outside. Thus, vesicles are not a mechanism of passive transport themselves.
Does Transcytosis combine diffusion and active transport?
Transcytosis is a cellular process that involves the transport of molecules across a cell via vesicles. It combines aspects of both endocytosis (a form of active transport) and exocytosis, allowing substances to move from one side of the cell to the other. While the vesicle transport requires energy (active transport), the actual movement of molecules within the vesicles can also involve diffusion. Thus, transcytosis incorporates both active transport and diffusion in its mechanism.
Does diffusion use vesicles?
No, diffusion does not use vesicles. Diffusion is a passive process in which molecules move from an area of higher concentration to an area of lower concentration without the use of vesicles. Vesicles are used in active transport processes like endocytosis and exocytosis.

What is a process by which cells release their contents?
Exocytosis is the process by which cells release their contents in form of vesicles. This may also happen due to diffusion.
Why is endocytosis use for?
it is used for vesicles
Does exocytosis use vesicles?
Yes.

What is the use of carrier proteins for diffusion?
facilitated diffusion.
Does facilitated diffusion require the use of energy?
Facilitated diffusion does not require the use of energy.
In which process does the cell use a vesicles to move molecule out?
Exocytosis
How do cnidarians breathe?
They use diffusion to get air through there body walls.
