"Tight junctions perform two distinct functions: they seal the space between cells to restrict paracellular flow and they fence off plasma membrane domains to prevent the mixing of apical and basolateral membrane proteins" is true or false.
Sodium-potassium pumps move ___________________ ions _______________ of the cell and _____________________ ions ___________________ the cell. This causes the inside of the cell to have what type of charge? __________________________.
Fibroblasts are motile cells that “creep” about in the connective tissue of the body where they play a number of roles, including secretion of the extracellular matrix and initiating certain wound healing events. These cells do not usually have microvilli nor do they express the actin-binding protein villin; both of these properties are characteristic of certain epithelial cells, such as those lining the intestine and kidneys. Remarkably enough, however, if one artificially engineers fibroblast cells to produce the villin protein, microvilli form on the fibroblasts. Given what you know about the function of villin, why might this striking change in cell morphology occur?
The plasma membrane is composed of a phospholipid bilayer with embedded protein. What is one of the functions of the embedded protein.
Tissue injury can result in either regeneration or healing. Explain the similarities and differences between these responses, highlighting the significance of the Extracellular Matrix
Muscle cells require a lot of energy to operate normally. Thus, muscle cells likely contain a high number of: [Select the best answer. ] mitochondria lysosomes vacuoles nuclei transport vesicles smooth endoplasmic reticulum rough endoplasmic reticulum golgi complexes ribosomes
Because the plasma membrane is selectively permeable, nothing can diffuse through the bilayer. True or False

(draw a schematic figure) Describe micelles and liposomes (if needed, draw a figure). The plasma membrane is ___________permeable. Describe how an active transport works (with an example _________ channel). In the Na+/K+ channel, how many ions move across the membrane?
There are specific regions within the cell membrane known as cell membrane domains. Discuss cell membrane domains, their formation, and highlight their importance in cellular functions. You should use examples to elaborate.
Which of the following statements related to intercellular junctions is false? Cadherins are important cell-cell adhesion proteins. A cadherin-mediated junction involves many cadherin molecules to achieve strong adhesion. The cytoplasmic domain of cadherins interacts with actin or intermediate filament cytoskeleton through adaptor proteins. Because tight junctions seal the membrane of adjacent epithelial cells, transmembrane proteins in the apical portion of the plasma membrane cannot move to the basal lateral domain or vice versa. Proteins can diffuse through an open gap junction.
