Do large cells move across the cell membrane quickly?
A large cell will never move across an intact cell membrane.
Does Phagocytosis move substances out of a cell?
Phagocytosis is the process of moving solids across a cell membrane into a cell.
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.
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.
What would happen if materials could not move across the cell membrane?
Isolation. And most materials can NOT move across the cell membrane. (For many things your cells have special proteins within the membrane for transport.)
Which one moves faster across the cell membrane the large or the small?
Small particles move faster across the membrane.
What would happen to a cell if materials could not move across the cell membrane?
it will died
What channel can help move things across the membrane?
Protein channels help move particles across the cell membrane
What 2 materials move across the cell membrane?
waste and nutrients
Does Phagocytosis move substances out of a cell?
Phagocytosis is the process of moving solids across a cell membrane into a cell.
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
