What else can I help you with?
Which molecules difuse through the lipid portion of the plasma membrane?
Only nonpolar (hydrophobic) molecules can pass through the bi-lipid membrane. For example, hormones are nonpolar, and they can pass through the membrane.
Where are you least likely to find water in the plasma membrane?
You are least likely to find water in the hydrophobic interior of the lipid bilayer of the plasma membrane. Water tends to be excluded from this region due to the hydrophobic interactions between the lipid molecules.
What molecules diffuses through the lipid portion of the plasma membrane?
Any hydrophobic ones. eg. steroids
What is the outside layer of a plasma membrane are made up of?
The outside layer of a plasma membrane is made up of a double layer of phospholipid molecules. These molecules have a hydrophilic (water-attracting) head and hydrophobic (water-repelling) tail, creating a lipid bilayer that forms the structure of the membrane.
What substance is most likely to passively diffuse across the plasma membrane by dissolving in the membrane?
Nonpolar molecules like lipid-soluble substances (e.g., steroid hormones, oxygen, and carbon dioxide) are most likely to passively diffuse across the plasma membrane by dissolving in the lipid bilayer. This type of diffusion does not require a specific transport protein and can occur directly through the phospholipid bilayer due to the molecules' hydrophobic nature.
Where in a cell does the production of protein carbohydrate and lipid molecules occur?
Protein= Ribosomes. Carbohydrate= Plasma Membrane Lipid= Lipid Bilayer
What molecules would be most likely to pass through the lipid bilyer of a plasma membrane?
ions and polar molecules
What color tube for lipid panel?
A yellow tube is typically used for lipid panels.

The plasma membrane is a bilayer of lipid molecules with protein molecues embedded True or False?
it depends on what you are referring to. the lipid bilayer is exactly what it says.it is two layers compsed of lipids. lipid molecules have two properties: a hydophobi tail and a hydrophilic head. so when the bi layer is put together, it has the tails facing eachter and the heads out to react with water conditions in the body. the membrane is also embedded with proteins of all dffierent kinds that allows ions to cross and this allows for cell communication
What is a holes in plasma membrane through which molecules pass across capillary wall?
The plasma membrane is made up of a lipid bilayer and some proteins. The transmembrane proteins are the structures which are involved in the transport of molecules in or through the cell.

What is the Plasma membrane lipid that improves the rigidity of the plasma membrane and increases the membrane's impermeability to water?
Cholesterol is the plasma membrane lipid that improves rigidity and reduces permeability to water due to its ability to pack tightly between the phospholipid molecules, increasing membrane stability.
What does plasma mainly contist of?
hormones, sugars, protein, antibodies, vitamins, carbon dioxide
