Visit this link (http://openstaxcollege.org/l/diffusion) to see diffusion and how it is propelled by the kinetic energy of molecules in solution. How does temperature affect diffusion rate, and why?
A scientist compares the plasma membrane composition of an animal from the Mediterranean coast with one from the Mojave Desert. Which hypothesis is most likely to be correct? The cells from the Mediterranean coast animal will have more fluid plasma membranes The cells from the Mojave Desert animal will have a higher cholesterol concentration in the plasma membranes The cells’ plasma membranes will be indistinguishable The cells from the Mediterranean coast animal will have a higher glycoprotein content, while the cells from the Mojave Desert animal will have a higher lipoprotein content.
In the fluid mosaic model: plasma membrane proteins orient their hydrophilic sides toward the internal bilayer. phospholipids often flip-flop between the inner and outer layers. the mosaic refers to proteins attached to the underlying cytoskeleton. the fluid refers to the phospholipid bilayer. the mosaic refers to the symmetry of the internal membrane proteins and sterols.
The principal force driving movement in diffusion is______. a. temperature b. particle size c. concentration gradient d. membrane surface area
Our current concept of the plasma membrane is called the fluidmosaic model. Why?
Dane is doing an experiment by using a dialyzing membrane as a model for cell membrane to observe the movement of the substances like glucose in before and after fluids using benedict's test. BEFORE: Fluid in the beaker blue (absence of glucose) Fluid in the bag orange (presence of glucose) AFTER Fluid in the beaker orange (presence of glucose) Fluid in the bag orange (presence of glucose) Was there a movement of glucose across the artificial membrane? Why or why not?
"Which of the following cell processes depend on the movement of membrane components and would not be possible if membranes were rigid, nonfluid structures?" cell movement cell division cell eating (phagocytosis) or cell drinking (pinocytosis) all of the given are not possible with rigid nonfluid structures.
An artificial cell consisting of an aqueous solution enclosed in a selectively permeable membrane (but with no cell wall) is immersed in a beaker containing an aqueous solution. The outside environment concentration consists of 0.01 M glucose and the inside of the cell has a concentration of 5.0 M glucose. The plasma membrane is permeable to water and monosaccharides, but impermeable to the disaccharides. Complete the following for the image below: Is the solution inside the cell isotonic, hypotonic, or hypertonic? Is the glucose going down or against its concentration gradient? Draw solid arrow to indicate the movement of the solute into or out of the cell. Draw a dashed arrow to show the movement of water. Will the artificial cell become lyse, shrivel, or stay the same?
Below are listed molecules with different chemical characteristics. Knowing that all molecules will eventually diffuse across a phospholipid bilayer, select the list that most accurately predicts the relative rates of diffusion of these molecules (fastest to slowest) across a biological membrane. alanine, propanol, sodium, estrogen sodium, propanol, alanine, estrogen estrogen, propanol, sodium, alanine estrogen, propanol, alanine, sodium

The following are the characteristics of the setup depicted below: The left side has a higher concentration of "yellow spheres" than the right side. The blue solution is water, and the yellow spheres dissolve in water (i.e. are osmoles). The dotted orange line is a semi-permeable membrane with characteristics exactly the same as a cell's plasma membrane. Below are TWO "If" statements that are separate questions. IF the yellow spheres are freely permeable across the dotted line, the process of [ Select ] ["facilitated diffusion", "active transport", "simple diffusion", "osmosis"] will occur. Consequently, the volume of water on the left side will [ Select ] ["stay the same", "decrease", "increase"] IF the yellow spheres cannot cross the membrane at all, the process of [ Select ] ["osmosis", "facilitated…
What happens to phospholipid mobility when the cell is treated with agents that disrupt the underlying membrane skeleton? options: Their mobility is unchanged. Their mobility is increased because the fences that normally restrict their diffusion are removed. Their mobility is decreased because the fences that normally restrict their diffusion are removed. Their mobility is increased because the treatment raises the temperature.
