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.
What process requires membrane proteins but not energy?
Facilitated diffusion is a process that relies on membrane proteins to transport molecules across the cell membrane without the need for energy input. These proteins act as channels or carriers to facilitate the movement of molecules from an area of high concentration to an area of low concentration.
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.
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.
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.

In osmosis What molecule does not move across the membrane?
In osmosis, large molecules like proteins and polysaccharides do not move across the membrane. Only smaller molecules such as water and ions can pass through the membrane during osmosis.
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.

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.
Is osmosis a movement of proteins?
No, in osmosis water molecules move from higher water concentration to a lower concentration through a semi-permeable membrane. Proteins are much smaller matter.
Does osmosis or facilitated diffusion require the presence of membrane channels?
Facilitated diffusion requires the presence of membrane channels or transporters to move molecules across the membrane. Osmosis, on the other hand, does not require membrane channels as it involves the passive movement of water molecules through the lipid bilayer of the membrane.
Does diffusion require integral proteins in the cell membrane?
no
What molecules during osmosis does not move across the membrane One example?
Large molecules such as proteins are typically unable to move across the membrane during osmosis. One example is starch molecules, which are too large to pass through the membrane pores.
What process do water molecules cross the cell membrane?
Water molecules cross the cell membrane through a process called osmosis, which is driven by the concentration gradient of water inside and outside the cell. Aquaporin proteins on the cell membrane facilitate the movement of water molecules into and out of the cell.
