According to the fluid-mosaic model of the plasma membrane, a.protein and phospholipids form a regular, repeating structure. b.the membrane is a rigid structure. c.phospholipids form a double layer, with the polar parts facing each other. d.proteins are free to move within a double layer of phospholipids.
Which of the following describes the fluid mosaic model of the plasma membrane structure? a. The lipid bilayer is solid at body temperature, thus protecting the cell. b. The phospholipid bilayer is embedded with associated proteins, cholesterol and sugars and has a dynamic arrangement. c. The plasma membrane is composed of two layers of proteins embedded with lipids. d. Phospholipids consist of a polar head and a nonpolar tail made of three fatty acid chains
Provide 3 hypotheses about the fluidity and mosaicity of the cell membrane. Write the hypotheses in "IF-THEN" statement form. Example: If the detection tests result in a change of color, appearance, or pH value of the solution, then there is a movement of glucose, starch, NaCl, or H+ ions across the semi-permeable dialyzing membrane bag, and it is a good model.

Substances available which are permeable to the DM include 0.02 M NaCl, 0.03 M glucose, and 0.01 M glucose. The only substance available which is completely impermeable to the DM is the 0.01 M lactose. Using the substances given and materials such as a beaker, stirring rod, and string, draw ONLY ONE set-up that can be demonstrated by Ms. Sassa that will satisfy ALL of the following conditions: a. No solute will exhibit a net diffusion out of the cell. b. Glucose will exhibit a net diffusion into the cell. c. NaCl will exhibit a zero net movement. d. No net movement of lactose from the inside to outside of the cell. Make sure to label properly the substance inside the beaker and inside the DM bag.arrow_forwardDescribe the properties of the three classes of membrane proteins (integral, peripheral, and lipid-anchored) along: A. differences from each other B. variation among themselvesarrow_forward

This type of protein is most likely a(n) a. peripheral membrane protein with additional hydrophobic domains b. integral membrane protein with a transmembrane domain c. a cholesterol-like molecule that is positioned in the phospholipid bilayer d. membrane phospholipid with hydrophilic head group e. soluble enzyme anchored to a scaffolding protein on the cytoplasmic side of the plasma membranearrow_forwardWhat is the primary characteristic of peripheral membrane proteins? A: They cannot be post-translationally modified. B: They span the entire lipid bilayer, sometimes multiple times. C: Detergents or nonpolar solvents are necessary to remove them from the lipid bilayer. D:Weak intermolecular forces keep them attached to the lipid membrane.arrow_forwardFor the following scenarios, determine whether the molecules in the scenario are moving by simple diffusion (S), osmosis (0), facilitated diffusion (F), or active transport (A). a)For water to travel across the cell membrane at a substantial rate, the water molecules travel through protein channels known as aquaporins b)While water molecules are polar, they are also very small. Some water molecules are able to squeeze directly through the phospholipid bilayer due to their small size. C)Charged ions such as Na* travel through a cell membrane against their concentration gradient d)Cells lining the gut need to take in glucose, but at certain times, the concentration of extraceliular glucose is lower than the concentration already stored in the cells. e)At a certain time, glucose is in a high concentration outside of a cell and needs to travel through the membrane into the cell but does so using a glucose transporter protein.arrow_forward
