What else can I help you with?
The process where a nonpolar molecule can just passively get across a membrane is called?
facilitated diffusion
What uses a protein to move a molecule across a cell membrane without using energy?
Facilitated diffusion uses proteins to move a molecule across the cell membrane without energy.
What is it called when a cell membrane closes around a molecule to allow the molecule to enter the cell?
selectively permiable membrane (you might want to double check that though...)
What is it called when transport proteins to help large molecules like glucose across the cell membrane?
Facilitated diffusion is the process by which transport proteins help large molecules like glucose cross the cell membrane. These proteins create a channel or carrier mechanism that allows the molecule to move across the membrane along its concentration gradient.
Why cant glucose be able to move across a cell membrane by simple diffusion?
Glucose is a large and polar molecule, which makes it difficult to pass through the hydrophobic interior of the cell membrane. As a result, glucose requires specific transporter proteins to facilitate its movement across the membrane.
What is the movement of small molecule across a cell membrane up its concentration gradient called?
eflux
The process where a nonpolar molecule can just passively get across a membrane is called?
facilitated diffusion
What is it called when molecule moves across a membrane through a protein channel without using energy?
Passive Transport
What is it called when a molecule moves across a membrane through a protein channel without using energy '?
Passive Transport
What is it called when a molecule moved across a membrane through a protein channel without using energy?
Passive Transport
What is it called a molecule moves across a membrane through a protein channel without using energy?
Passive Transport
When a protein helps a molecule across the membrane is?
the processe is called osmosis Try again, this time use the term "facilitated transport" since a protein molecule is helping.
A special molecule that uses energy to push molecules through a membrane of a cell is called?
The special molecule is called ATP, which stands for adenosine triphosphate. ATP provides the necessary energy to power transport proteins in the cell membrane to move molecules across it.
What is the transport of water across the cell membrane called?
Movement of water across a membrane is called OSMOSIS.
What is it called when part of the cell membrane closes around a molecule to allow the molecule to enter it?
This is called endocytosis.
What uses a protein to move a molecule across a cell membrane without using energy?
Facilitated diffusion uses proteins to move a molecule across the cell membrane without energy.
What is it called when part of a cell membrane closes around the molecule to allow the molecule to enter the cell?
This is called endocytosis.
