Active transport

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
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 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.
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
What does facilitated diffusion requires?
Facilitated diffusion requires the presence of specific carrier proteins embedded in the cell membrane to help transport molecules across the membrane. These carrier proteins assist in the movement of molecules down their concentration gradient without requiring energy input from the cell.
What ways of moving molecules across a membrane requires energy?
Active transport requires energy to move molecules across a membrane against their concentration gradient. This process is facilitated by specific carrier proteins embedded in the membrane that use energy, usually in the form of ATP, to transport molecules.
