What requires the use of energy and the help of transport proteins to move a molecule across the cell membrane?
Facilitated diffusion
What requires the use of energy and help of transport proteins to move a molecule across a cell membrane?
Facilitated diffusion
What is the molecule that requires energy to pass through the cell membrane?
The molecule that requires energy to pass through the cell membrane is typically an ion or a large polar molecule, such as glucose, which moves against its concentration gradient. This process is known as active transport and involves the use of ATP or other energy sources to facilitate the movement of these substances through specific transport proteins in the membrane. Examples include sodium-potassium pumps and glucose transporters.
What form of passive transport always requires membrane-bound proteins?
Facilitated diffusion
Does active transport require a membrane?
Yes, active transport requires a membrane because it involves the movement of molecules or ions against their concentration gradient, which requires energy expenditure. This process is facilitated by specific transport proteins embedded within the membrane.

Facilitated diffusion
Which type of transport requires assistance from membrane proteins?
Active transport requires assistance from membrane proteins. These proteins, such as ion pumps and carrier proteins, help move molecules against their concentration gradient, requiring energy input to drive the process.

What process requires energy to bring molecule across the cell membrane?
active transport
What type of transport requires energy move a molecule?
Active transport requires energy to move a molecule.
A type of passive transport across a cell membrane that requires special carriers is?
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.
What is A large glucose molecule requires facilitated diffusion but an oxygen molecule referring to?
A large glucose molecule requires facilitated diffusion because it is too big to pass through the cell membrane without assistance from transport proteins. In contrast, an oxygen molecule is small enough to diffuse freely across the cell membrane through simple diffusion due to its size and hydrophobic nature.
Does osmosis require membrane proteins?
No, osmosis is a special type of diffusion in which a water molecule is able to passively transport through a membrane without a protein. Although it is polar, it's extremely small size makes this possible
