One factor that influence the passage of substances through living membranes are size which small molecules pass faster than large. Others are the charge non polar are faster and concentration gradient molecules that move to regions of lower concentration.

∙ 13y agoThe main factor that influences diffusion of a substance across a cell membrane is the concentration of the diffusing molecule. If it is high on one side and low on another it will diffuse to the area of lower concentration. Another factor that influences diffusion across a cell membrane would be the pore. Is the molecule large enough to fit through the pores of the membrane? Does the molecule have the correct charge with regards to the charge on the inside of the pore to allow it to pass through?

Wiki User
∙ 9y agoThe diffusion of different substances through a membrane depends on the size of the particles of the substance. The smaller the particles, the higher the rate of diffusion.

A material that will not permit the passage of electricity is called what?
It is an insulator.
What is passage of gas through the anus is?
first thats gay
What is the transition word after after that?
There is no way to answer this without more information. A transition word is a word used to connect two parts of a passage or quotation, so to complete your question you need to supply the passage or quotation.
What is the second step when evaluating writing with a general rubric?
Read the passage

Hes discovered the north west passage
Do some membranes have proteins with chanels that allow for the passage of hydrophilic substances?
true
Is this true some membranes have proteins with channels or pores that allow for passage of hydrophilic substances?
yes it's true.
What membranes line the nasal passage?
Mucus
Passage of water through cell membranes?
Osmosis
What does it mean to say most biological membranes are selectively permeable?
Selectively permeability is a property of biological membranes that allows them to regulate the passage of substances across them. In spite of heavy traffic through them, cell membranes are selectively permeable, and substances do not cross the barrier indiscriminately.
How do these gates functions in a similar way to the sell membrane?
Gates and select membranes both act as barriers between two different environments. The main difference between the two is that gates are designed to open and close while select membranes are designed to remain in a single state. This allows for specific control over the environment on either side of the barrier. In terms of functionality gates and select membranes have a number of similarities. Both act as a barrier between two environments and allow for the passage of certain substances while blocking the passage of others. This can be accomplished by the use of filters or by a combination of physical and chemical barriers. In addition both gates and select membranes may be used to isolate a specific area such as a laboratory or manufacturing facility. When it comes to the similarities between gates and select membranes the most notable is their ability to regulate the flow of substances. This is accomplished through the use of filters and other mechanisms that block certain substances while allowing others to pass. This is particularly useful in applications such as pharmaceutical processing where specific compounds need to be kept isolated from one another. Additionally both gates and select membranes can be used to monitor the movement of substances alerting personnel if something is out of the ordinary. Overall gates and select membranes share many similarities when it comes to their ability to regulate the flow of substances between two environments. They both act as a barrier and can be used to filter out specific substances monitor the movement of substances and isolate specific areas. However the main difference between the two is that gates can open and close while select membranes remain in a single state.
What does Selective permeability do?
It allows the passage for certain substances.
What is the passage of carbon dioxide from the air into the leaves?
At the least this passage takes place via diffusion; introduce membranes and we find trans-spiration [from respire].
What factors control passage of molecules in and out of cell?
Transport control factors.
What does the cell membrane do in an animal cell?
Regulates the passage of substances into and out of the cell.
What does cell membranes do in the animal cell?
It selectively regulates the passage of substances into and out of the cell. It is a very important part of a cell.the cell membrane holds all of the stuff inside of the cell. Also it shapes the cell that is how a animal cell is circles and a plant cell is squared.Read more: What_does_the_cell_membrane_of_the_animal_cell_do
What are the membranes of what have tiny pores that allow the passage of water molecules?
Plant leaves. The pores are called stomata.
