What else can I help you with?
Do large cells move across the cell membrane quickly?
A large cell will never move across an intact cell 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 hormone does NOT require a messenger to move it across the cell membrane?
adh
Can substances move in and out of the cell membrane?
Yes, how else could the cell live. Cell membranes have structures (holes) in them to allow things to move in and out. These holes are special structures in the membrane and they "control" what goes across the membrane. I have made a link below to a diagram of the cell membrane to show some of these structures.
What type of molecule can be used as a tunnel to move compounds across the cell membrane?
Carrier proteins are a type of molecule that can be used as a tunnel to move compounds across the cell membrane. These proteins bind to specific molecules and undergo conformational changes to transport them across the membrane. This process is known as facilitated diffusion.
Do large cells move across the cell membrane quickly?
A large cell will never move across an intact cell membrane.
What does diffusion do in a cell?
Move things across the cell membrane.
Which one moves faster across the cell membrane the large or the small?
Small particles move faster across the membrane.
What does a carrier protein do in the process of transporting molecules across a cell membrane?
A carrier protein helps transport molecules across a cell membrane by binding to specific molecules and changing shape to move them across the membrane.
What 2 materials move across the cell membrane?
waste and nutrients
What uses a protein to move a molecule across a membrane without energy?
Facilitated diffusion uses proteins to move a molecule across the cell membrane without energy.
If the inside and outside of a cell are both isotonic does water still move across the cell membrane?
no
How do large cells move across the cell membrane?
There cannot be large cells inside a cell.
How does cell membrane structure work to move molecules across the membrane passively and actively?
Cheese toast
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 hormone does NOT require a messenger to move it across the cell membrane?
adh
What requires no energy to move things across the cell membrane?
