Membrane lipids have fatty acid tails and, like triacylglycerols, their properties are governed by the properties of these tails. Based on what we saw with dietary lipids, which membrane would have more fluid characteristics – the one with more saturated fatty acids or the one with more unsaturated fatty acids? Explain your reasoning. Look at the structure of cholesterol. Cholesterol is a necessary component of biological membranes. What do you think cholesterol would do to the structure of a membrane...
Make a diagram of the fluid mosaic model of the structure of cell membranes. Label: phospholipid molecules, cholesterol, hydrophilic and hydrophobic portions, proteins, and carbohydrates. Describe the structure, arrangement and functions of membrane lipids, membrane proteins and membrane carbohydrates.
Lo 8: Properties of the Plasma Membrane 1) Draw the structure of a phospholipid and label the three parts: Glycerol backbone, fatty acid tails and phosphate head group. Label which regions are hydrophobic and which are hydrophilic. Be able to explain WHY they have the property they do (think of their chemical make up-look it up if you need a reminder). 2) Describe two properties that affect membrane fluidity? Draw a representation of how each property affects membrane fluidity. Explain...
Which specific types of lipids would be most enriched on the plasma membrane of neurons and absorptive epithelial cells be specific please/ detail
Describe the distribution of lipids in a biological membrane. What determines their distribution and why is it maintained?
Describe the different types of lipids and their special characteristics. Give examples where appropriate.
What functions of a membrane would be compromised if the membrane consisted of a phospholipid bilayer without proteins? Give at least 3 specific examples.
18. Describe the fluid mosaic model of the membrane structure. 19. What factors limit membrane protein motility?
3. Many membrane process such as transport or signal transduction depends on the fluidity of lipids membrane. How fatty acids and cholesterol effect the fluidity of the membrane.
2. What are the physical properties that constitute the Membrane, all structures associated with it? 3. What are the proteins and their specific functions within the membrane?
