What is the definition of protein gate?
A protein gate is a pathway through a protein molecule on the plasma membrane in which ions and small molecules can diffuse in or out of a cell.
Why do oxygen molecules easily diffuse across a cell membrane while protein molecules do not?
Cell membrane is semipermeable and oxygen molecules have size required for easy passqge while Glucose molecules do not have that size required for easy passage.
When a protein channel allows molecules to cross through the cell membrane?
when a protein channel allows molecules to cross through the cell membrane this is called facilitated diffusion. many might mistake this for diffusion which is the process by which molecules tend to move from an area where they are more concentrated to an area where they are less concentrated.
How do you transport proteins in a cell make it easier for certain molecules to diffuse across a membrane?
If there's a transfer protein then its NOT diffusion ... its active transport.
What molecules would easily be able to diffuse through a cell membrane without the help of a transport protein?
Water, any small molecule and lipids.
Transport protein that provides a tubelike opening in the plasma membrane through which particles can diffuse?
Channel Protein.
What is the definition of protein gate?
A protein gate is a pathway through a protein molecule on the plasma membrane in which ions and small molecules can diffuse in or out of a cell.
What protein recognizes certain molecules bringing them across a membrane?
channel or transport or receptor
Why do you have diffusion?
so molecules can use protein channel to cross a cell membrane-cleo
A specific protein that recognizes certain molecules bringing them across the membrane?
Receptor Protein.
Why do oxygen molecules easily diffuse across a cell membrane while protein molecules do not?
Cell membrane is semipermeable and oxygen molecules have size required for easy passqge while Glucose molecules do not have that size required for easy passage.
The proccess by which a protein channel allows molecules to cross the cell membrane is called?
Facilitated diffusion
What is this statement most likely referring to Small nonpolar molecules may pass through this structure but others require a protein channel?
Small non-polar molecules may pass through a a semipermeable membrane but others require a protein channel.
When a protein channel allows molecules to cross through the cell membrane?
when a protein channel allows molecules to cross through the cell membrane this is called facilitated diffusion. many might mistake this for diffusion which is the process by which molecules tend to move from an area where they are more concentrated to an area where they are less concentrated.
How do you transport proteins in a cell make it easier for certain molecules to diffuse across a membrane?
If there's a transfer protein then its NOT diffusion ... its active transport.
What is the fuction of protein channel in the cell membrane?
to either absorb/excrete whole protein molecules that are produced in other/same cell(s).
Which is a factor that determies whether a mole can cross a cell membrane?
Lipid solubility determines if it will diffuse across. The presence of specific protein carrier molecules determines if it will be transported across the membrane.
