What part of phospholipid molecule would reject the polar molecule glucose?
The non-polar part (the hydrophobic tail of the phospholipid)
Do lipid molecules need phospholipid translocators to pass through cell membrane?
Lipid molecules are what make up the cellular membrane. Lipids are mostly composed of phospholipids creating a phospholipid bilayer. Each phospholipid has a polar head and a non polar tail. There are two layers of phospholipids composing the bilayer with non polar tails facing towards eachother. Each layer is known as a leaflet. The phospholipid translocators are designated to 'flip-flop' the phospholipids between each leaflet to increase fluidity of the membrane.
How does polar phospholipid form a bilayer?
A lipid bilayer forms spontaneously whenever a collection of phospholipids is placed in water. This is because the amphipathic lipids (lipids having both polar and nonpolar regions) double up and put hydrophilic ends toward the outside and inside of the cell, whereas the hydrophobic tails are held in between the heads. A phospholipid is comprised of 1 polar head and two non-polar (fatty-acid) tails o<>o The polar region is comprised of a phosophate group (water-soluble) The non-polar region is comprised of fatty acids (water-insoluble)
What is a bilayer?
A lipid bilayer is a double layer membrane formed from phospholipids. Phospholipids are composed of a polar head group and non-polar fatty acid tails. The arrangement of the phospholipids makes the cell membrane permeable.
Is soap polar or non-polar?
Soap is actually both. It is similar to a phospholipid in that it has a polar head and a nonpolar tail.
Is there a part of a phospholipid bilayer that is polar?
The tails, the part that doesn't contain phosphorus, are non polar and they are hydrophobic (afraid of water).
The part of a membrane protein that extends through the phospholipid bilayer is primarily composed of amino acids that are?
non-polar
A molecule with a polar head and two non polar tails?
Lipids, man!Could be the phospholipid bilayer of a cell membrane to be more specific.phospholipidSoap and detergent molecules have a polar head and nonpolar tail to help dissolve an dwash off dirt and oil.
What part of phospholipid molecule would reject the polar molecule glucose?
The non-polar part (the hydrophobic tail of the phospholipid)
What part of a phospholipid is polar and non-polar?
The phospholipid bilayer in cell membranes is both polar and nonpolar. The heads, which face the outside and inside of the cell, are polar. Thus they form hydrogen bonds with the water outside of the cell and the cytoplasm inside the cell. They are called "hydrophilic," which means they love water. The tails are on the inside of the bilayer and are nonpolar. They are hydrophobic, which literally means they are scared of water.
What part of a phospholipid is non polar?
The head (or top) of a phospholipid is polar and the carbon chain tail is non-polar.

The water soluble portion of a phospholipid is the polar head which generally consists of a glycerol molecule linked to a phosphate group?
No, you do not have that quite correct. A Phospholipid molecule has one end that is hydrophilic (is attracted to water) while the other end is hydrophobic (is repelled water but is attracted to fats).
Why are fat soluble molecules the only molecules that permeate across a cell membrane?
Because small non polar molecules are the ones able to cross due to the fact that the membrane consists of a phospholipid bilayer where the middle is composed on non polar tails
What has a polar head and non polar tail in a cell?
The phospholipid bilayer, otherwise known as the cell membrane contains many structures such as these. The individual units you speak of are called phopholipids, and are usually desribed as having a hydrophilic (polar) head group and a hydrophobic (non-polar) tail group. Hope this helps
