What molecules have the most difficult time passing through the cell membrane alcohol or oxygen gas or carbon dioxide gas or sodium ion?
CynthiaLorraineWilli...
Firstly, sodium ions would never get past the membrane without a carrier protein, ions (charged atoms) don't go through the membrane on their own. If the cell has a protein carrier capable of transporting the sodium ion, if there's water in the environment to encapsulate the ion so that it can go through and if the cell has ATP to spend then it shouldn't be too difficult.
Secondly, oxygen and carbon dioxide gas? There shouldn't be gas in your bloodstream to begin with. Non gaseous O2 and CO2 cannot diffuse passively into cells quite easily based on concentration gradients. They're small but apolar molecules.
Alcohol comes in many forms, you have bigger and smaller alcohol molecules. It's polar, and so is the part of the membrane that is facing the outside and inside of the cell, but the middle part is apolar, so any molecule such as alcohol might have a few problems going through there, especially the bigger molecules.

How many moles of carbon dioxide are in 2.22 1023 molecules of carbon dioxide?
2,22 1023 molecules of carbon dioxide is equal to 0,368 moles.
What are the products of ethyl alcohol and carbon dioxide?
Carbon dioxide may be a product of the ethanol fermentation.
Why are carbon dioxide molecules important for metabolism in living things?
Carbon dioxide molecules are very important for photosynthesis
Can carbon dioxide attract carbon dioxide?
When carbon dioxide is a gas, the molecules repel each other. When carbon dioxide is a solid the molecules do attract each other, and bond in a crystalline structure.
If air had a million molecules how many carbon dioxide would be in it?
Air contains 0.93 % Argon In a million molecules of air there would be 1,000,000 x 0.93/100 = 9300 molecules of Argon
What can not cross the semipermeable membrane?
sugar molecules
What are 3 molecules that pass through the lipid bilayer of the cell membrane?
oxygen, carbon dioxide, and water
Which substance could pass through the cell membrane readily?
Small molecules, such as water, oxygen, and carbon dioxide.
When one molecule of glucose undergoes alcohol fermentation what products and how many molecules of each of them account for the 6 carbon atoms?
2 molecules of ethanol and 2 molecules of carbon dioxide
Why can oxygen water and carbon dioxide move through the cell membrane but salt and protein cannot?
That depend on size and the charge.Large molecules and charged molecules cannot move freely
What molecule is able to easily diffuse across the cell's membrane?
Carbon dioxide, oxygen and some nonpolar molecules diffuse easily.
What are 3 substances the can move in and out of the cell?
alcohol, water, oxygen and carbon dioxide can all dissolve through the lipids in the cell membrane.
Which substance may enter a cell membrane by simple diffusion?
Water, certain ions, air and glucose molecules.
What materials crossed the membrane and why did they cross?
Materials that can cross the cell membrane include small non-polar molecules like oxygen and carbon dioxide, as well as small polar molecules like water. These molecules can freely pass through the lipid bilayer of the membrane due to their small size and compatibility with the hydrophobic environment of the lipid tails. However, larger molecules and charged ions require specific protein channels or transporters to cross the membrane.
What does partially permeablele mean?
For a cell membrane, partial permeability means that only certain molecules can pass through like carbon dioxide and oxygen while other molecules such as glucose cannot.
How do the small molecules of oxygen and carbon dioxide move through the cell membrane?
They move via diffusion across a gradient.
An organism lives in a container with very little oxygen It produces ethanol and carbon dioxide as waste products Which process does it use to produce most of its ATP molecules?
The organism uses the process of alcohol fermentation to produce most of its ATP molecules.
