What macromolecule is involved in facilitated diffusion?
Facilitated diffusion involves the transport of molecules across the cell membrane with the help of transport proteins. These transport proteins are typically made up of proteins, which are macromolecules. Therefore, macromolecules involved in facilitated diffusion are proteins.
Which type of transport occurs when a membrane protein binds to a molecule on one side of the cell membrane and then releases it on the other side?
Facilitated diffusion occurs when a membrane protein binds to a molecule on one side of the cell membrane and then releases it on the other side. This type of transport does not require energy and relies on the concentration gradient to move molecules across the membrane.
What used a protein to move a molecule across a cell membrane without energy?
Facilitated diffusion uses proteins to move a molecule across the cell membrane without energy.
What type of transport does a small molecule enter a cell with help from a membrane protein additional energy is needed to complete this process?
Facilitated
What is the process by which substances are moved through the cell membrane by a carrier molecule?
facilitated diffusion or active transport
What does facilitated diffusion?
A transport protein, a large polar molecule, a semi-permeable membrane and a concentration gradient.
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
The movement of molecule down a concentration gradient through transport proteins in the cell membrane is a type of?
facilitated diffusion.
What three major processes of nutrient absorption must be combined with a carrier molecule for transport?
The three major processes of nutrient absorption requiring a carrier molecule for transport are facilitated diffusion, active transport, and cotransport (symport). These processes are essential for the absorption of nutrients such as glucose, amino acids, and ions in the small intestine. The carrier molecules help transport these nutrients across the cell membrane.
What is the difference between facilitated diffusion with the help of a carrier molecule with the help of a transport protein?
Facilitated diffusion is a type of passive transport (does not require energy). It is called facilitated diffusion because it utilises the carrier protein to diffuse through it. Active transport requires energy to pump certain big molecules to cross over and this uses transport protein. Basically, the difference is just the usage of energy.
Is glucose molecule passive or active transport?
Secondary active transport aka facilitated diffusion [depending on your teacher].
