Can nonpolar molecules cross the cell membrane?
Yes, nonpolar molecules can cross the cell membrane through simple diffusion.
How do you explain the phrase like dissolves like in terms of polar and nonpolar substances?
Polar substances dissolve other polar substances, and nonpolar substances dissolve other nonpolar substances. A polar substance cannot dissolve a polar substance and a nonpolar substance cannot dissolve a polar substance.
What are emulsions?
A polar and a nonpolar substance being made miscible together by another substance that has both polar and nonpolar characteristics.
What in diffusion biology?
Diffusion is the process that occurs when a certain concentrated volume of material moves to a less concentrated state. Facilitated diffusion is different and is done with the help of pumps actively transporting materials across the cell membrane to create the equilibrium on both sides of the membrane. ža specific type of passive transport žthe movement of particles from an area of high concentration to an area of low concentration ždissolved particles that are small or nonpolar can diffuse through the cell membrane ždiffusion is used to reach equilibrium –equilibrium: a condition in which the concentration of a substance is equal throughout a space
Which part of the cell membrane is nonpolar and prevent the cell from dissolving?
Nonpolar fatty acid chains are nonpolar and prevent the cell from dissolving.
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.
What is soluble in a nonpolar substance?
Typically nonpolar substances are soluble in other nonpolar substances. Like disolves like...
How do nonpolar regions of a membrane proteins cause proteins to be held in the membrane?
IB sucks
Why do small nonpolar molecules cross a membrane?
Small nonpolar molecules can cross a membrane easily because they are able to pass through the lipid bilayer of the membrane due to their size and lack of charge, allowing them to move freely across the membrane.
Hydrophobic interactions of the tails of phospholipids can produce a. a cytoskeleton. b. a protein membrane. c. a nonpolar membrane. d. a lipid bilayer. e. hydrolysis of the fatty acid?
a lipid bilayer
Is salad oil polar?
Yes, salad oil is a nonpolar substance because it is composed mainly of lipids, which are nonpolar molecules. This means that salad oil will not mix well with water, a polar substance.
What type of substance will dissolve in a nonpolar substance?
A non-polar substance will dissolve in a non-polar substance. Like dissolves like.
