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.


What substances can easily pass through a cell membrane?

Small, non-polar molecules like oxygen, carbon dioxide, and water can easily pass through a cell membrane.


What kind of molecules can easily pass through a cell membrane?

Small, Non-polar molecules. If the molecule is polar, it sticks to both sides of the membrane, and has to go through selective routes. The easiest to get through is the Non-polar (oxygen and carbon).


What types of molecules can easily go through your cell membrane are permeable to the cell membrane?

Substances with a hydrophillic-lipophillic balance are permeable through the cell membrane.


Which of the following molecules would be blocked by a cell membrane?

Large molecules such as proteins and nucleic acids are typically blocked by the cell membrane due to their size and complexity. Small, nonpolar molecules like oxygen and carbon dioxide can easily pass through the cell membrane through simple diffusion.


What substance will diffuse through a membrane?

Substances that are small, nonpolar, and uncharged will diffuse through a membrane easily. This includes gases like oxygen and carbon dioxide, as well as small lipophilic molecules. Larger or charged molecules may require assistance from transport proteins to cross the membrane.


Which substance would most easily pass through a cell membrane?

Small, non-polar molecules like oxygen and carbon dioxide would most easily pass through a cell membrane.


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 substances can pass through the cell membrane?

Substances that can pass through the cell membrane include small molecules like water, oxygen, and carbon dioxide, as well as certain ions and lipid-soluble molecules. Larger molecules and charged ions typically require specific transport proteins to cross the membrane.


How many molecules of carbon dioxide are used to produce one 6 carbon sugar molecule?

Six molecules of carbon dioxide are used to produce one 6-carbon sugar molecule through the process of photosynthesis.


What kinds of molecules pass through a cell membrane most easily?

Small and nonpolar molecules such as oxygen, carbon dioxide, and ethanol pass through a cell membrane most easily, as they can diffuse across the lipid bilayer without the need for transport proteins.
