The plasma membrane has a hydrophobic interior due to the two present in each phospholipid found in the phospholipid bilayer of the cell membrane. The plasma membrane allows some molecules to cross but not all. Therefore, the plasma membrane is said to be Molecules that are nonpolar and hydrophobic will cross the membrane with ease by Does this process require energy? When molecules move across the plasma membrane by passive transport, they will move down or with the from an area of concentration to an area of concentration. Polar, hydrophilic molecules and charged ions will move across the plasma membrane by the process of_ This does not require energy, but it does require a A special case of diffusion is known as _which is the movement of water across the plasma membrane. If a cell is placed into a solution that is hypertonic compared to the inside of the cell, the cell would water.

Cellular memberane are mainly constructed of a phospholipid bilayer with emnedden cholesterol and proteins. Tues or False
Lipid bilayers are said to behave like two-dimensional fluids. What does this mean? What drives the movement of lipid molecules and proteins within the bilayer? How can such movement be measured? What factors affect the degree of membrane fluidity
The composition of a cell membrane is not uniform for all types of cells.Some cell membranes are more rigid than others. Rigidity is determinedby a variety of factors, one of which is the structure of the carbon chains in the phospholipids that comprise the membrane. One example of aphospholipid was drawn, and another, having C–C double bonds in its carbon chains, is drawn here. Which phospholipid would be present in the more rigid cell membrane and why?
What type of molecule would easily pass through a pure phospholipid membrane (i.e. a membrane that has no ion channels)? Water Na+ Cl- None of these would easily pass through this membrane
In a typical eukaryotic plasma membrane, _____.A. lipids can move and diffuse through the bilayerB. oligosaccharides face outward, not toward the cytosolC. proteins can move in and out of the bilayerD. all of the above
"Although lipid molecules are free to diffuse in the plane of the bilayer, they cannot flip-flop across the bilayer unless enzyme catalysts called phospholipid translocators are present in the membrane", is true or false.
Glycophorin, a protein in the plasma membraneof the red blood cell, normally exists as a homodimer thatis held together entirely by interactions between its trans-membrane domains. Since transmembrane domains arehydrophobic, how is it that they can associate with oneanother so specifically?
A phospholipid bilayer with equal amounts of saturated and unsaturated fatty acids displays a specific permeability to glucose. What effect will increasing the proportion of unsaturated fatty acids in the bilayer have on the membrane's permeability to glucose?
The fluid mosaic model of membrane structure has been very useful in explaining membrane behavior. However, the description of membrane as proteins floating in a phospholipid sea is oversimplified. Describe some components of membrane that are restricted in their lateral motion.
Electronegativity is the ability for an atom or molecule to attract electrons (see chapter 2). Considering the components of theelectron-transport chain, with protein I being the beginning of the chain and protein IV the end of the chain, which end has thehigher electronegativity? Explain your answe
The cells of plant seeds store oils in the form of droplets enclosed by membranes. Unlike the membranes you learned about in this chapter, the oil droplet membrane consists of a single layer of phospholipids rather than a bilayer. Draw a model for a membrane around an oil droplet. Explain why this arrangement is more stable than a bilayer.
Which of the following statements are acceptable and why? [Whereas all the carbohydrate in the plasma membrane faces outward on the external surface of the cell, all the carbohydrate on internal membranes faces toward the cytosol.] [Although lipid molecules are free to diffuse in the plane of the bilayer, they cannot flip-flop across the bilayer unless enzyme catalysts called phospholipid translocators are present in the membrane.]
