No, simple diffusion does not require transport proteins. It is a passive process where molecules move from an area of higher concentration to an area of lower concentration directly through the lipid bilayer of the cell membrane. Transport proteins are involved in facilitated diffusion and active transport.

How does faciliated diffusion differ from simple diffusion?
Facilitated diffusion is a type of passive transport that involves the movement of molecules across a cell membrane with the help of specific transport proteins. In contrast, simple diffusion is also a type of passive transport, but it does not require the presence of transport proteins and relies solely on the concentration gradient for movement of molecules across the membrane.
Does transporting aquaporins proteins require ATP?
No, transporting aquaporin proteins does not require ATP. Aquaporins facilitate the movement of water across cell membranes through passive transport processes, such as osmosis or simple diffusion according to the concentration gradient. ATP is typically not needed for passive transport.
Does passive transport rely on diffusion or energy?
Passive transport relies on diffusion, which is the movement of molecules from an area of high concentration to an area of low concentration. It does not require energy input from the cell.
What types of transport mechanisms through the cell membrane are passive?
Passive transport mechanisms through the cell membrane include simple diffusion, facilitated diffusion, and osmosis. These processes do not require energy input from the cell.
What are the different types of passive transport?
The different types of passive transport include simple diffusion, facilitated diffusion, and osmosis. Simple diffusion is the movement of molecules from an area of higher concentration to an area of lower concentration. Facilitated diffusion involves the use of transport proteins to help molecules move across the cell membrane. Osmosis is specifically the diffusion of water across a selectively permeable membrane.
How does faciliated diffusion differ from simple diffusion?
Facilitated diffusion is a type of passive transport that involves the movement of molecules across a cell membrane with the help of specific transport proteins. In contrast, simple diffusion is also a type of passive transport, but it does not require the presence of transport proteins and relies solely on the concentration gradient for movement of molecules across the membrane.
What are the three transport processes that do not require cell energy?
Passive Transport,Facilitated Diffusion, and Simple Diffusion
How is active transport different than simple and facilitated diffusion?
simple and facilitated diffusion don't require energy and are forms of passive transport. Active transport requires energy
What is falicitated diffusion?
Facilitated diffusion is a type of passive transport where specific molecules are transported across the cell membrane with the help of transport proteins. Unlike simple diffusion, facilitated diffusion requires the presence of these proteins to facilitate the movement of molecules across the membrane.
Does transporting aquaporins proteins require ATP?
No, transporting aquaporin proteins does not require ATP. Aquaporins facilitate the movement of water across cell membranes through passive transport processes, such as osmosis or simple diffusion according to the concentration gradient. ATP is typically not needed for passive transport.
How is faciliated transport similar to simple diffusion?
Facilitated and simple diffusion both transport solutes along a concentration gradient and neither processes require any ATP expenditure.
Does simple diffusion require ATP?
No only active transport requires ATP.
In facilitated diffusion which process does not require energy?
Facilitated diffusion is a form of passive transport that does not require energy input from the cell. Instead, it relies on the assistance of transport proteins to move molecules across the cell membrane.
What are the two types of possive transport?
The two types of passive transport are simple diffusion and facilitated diffusion. Simple diffusion involves the movement of molecules across a cell membrane without the need for a specific protein. Facilitated diffusion, on the other hand, requires the assistance of specific transport proteins to move molecules across the membrane.
Does passive transport rely on diffusion or energy?
Passive transport relies on diffusion, which is the movement of molecules from an area of high concentration to an area of low concentration. It does not require energy input from the cell.
How simple diffusion can be distinguished from facilitated diffusion?
Simple diffusion does not involve the use of transport proteins and relies on the concentration gradient of molecules for movement across the membrane. Facilitated diffusion, on the other hand, requires specific transport proteins to help facilitate the movement of molecules across the membrane, often against their concentration gradient.
How does Facilitated diffusion differs from diffusion in that facilitated diffusion?
Facilitated diffusion involves the use of carrier proteins to move specific molecules across the cell membrane, while simple diffusion does not require proteins and involves the movement of molecules from an area of high concentration to low concentration. Facilitated diffusion is selective and allows for faster transport of specific molecules that may be too large or polar to diffuse freely through the membrane.
