No. Water molecules can fit in between the different components of the cell membrane, such as in between the phosholipid bilayers.
The same works for some noncharged molecules.
There is no point in using proteins if the molecules are small enough to fit between the cracks in the cell.
What else can I help you with?
Does osmosis require a membrane-bound carrier for transport?
No, osmosis does not require a membrane-bound carrier for transport. Osmosis is the passive movement of water molecules across a selectively permeable membrane from an area of lower solute concentration to an area of higher solute concentration. The process occurs spontaneously and does not require carrier proteins.
Does osmosis involve the use of proteins in its process?
Yes, osmosis does not involve the use of proteins in its process. Osmosis is the movement of water molecules across a selectively permeable membrane from an area of higher concentration to an area of lower concentration. This process does not require the use of proteins.
Does osmosis involve the use of transport proteins?
No, osmosis does not involve the use of transport proteins. Osmosis is the movement of water molecules across a selectively permeable membrane from an area of higher concentration to an area of lower concentration. Transport proteins are not involved in this process.
Which form of transport across the cell membrane does not require energy but a carrier protein?
Facilitated diffusion does not require energy but relies on carrier proteins to transport molecules across the cell membrane. The carrier proteins assist in the movement of specific molecules down their concentration gradient.
What are the protein molecules in a cell membrane that assist in cell transport?
Protein molecules are responsible for membrane transport. In passive transport diffusion is the phenomenon in which molecules flow naturally from areas of high concentration to lower concentrations.

facilitated diffusion.

Protein molecules are responsible for membrane transport. In passive transport diffusion is the phenomenon in which molecules flow naturally from areas of high concentration to lower concentrations.
Are aquaporins involved in osmosis or facilitated diffusion?
Aquaporins are involved in osmosis by facilitating the movement of water molecules across cell membranes. They do not participate in facilitated diffusion, which involves the transport of solutes across membranes with the help of carrier proteins.
What 2 transport processes use carrier proteins?
Two transport processes that use carrier proteins are facilitated diffusion and active transport. In facilitated diffusion, carrier proteins help move molecules across the cell membrane down their concentration gradient, while in active transport, carrier proteins help move molecules against their concentration gradient by using energy.
Does osmosis involve transport proteins?
No, osmosis does not involve transport proteins. Osmosis is the passive movement of water across a selectively permeable membrane in response to a concentration gradient. Transport proteins are involved in facilitated diffusion and active transport processes.
What carrier protein takes sugar into a cell with out energy?
osmosis
What type of proteins are used in facilitated diffusion?
Facilitated diffusion involves the use of integral membrane proteins known as carrier proteins or channel proteins to help transport specific molecules across the cell membrane. These proteins provide a pathway for the molecules to cross the lipid bilayer more efficiently than simple diffusion.
Is there another name for carrier proteins?
Yes, carrier proteins are also known as carrier molecules or transport proteins. They facilitate the movement of molecules across cell membranes by binding to specific substances and transporting them across the cell.
