Which specific types of lipids would be most enriched on the plasma membrane of neurons and absorptive epithelial cells
be specific please/ detail
Plasma membranes of neuron and epithelial cells enriched with phospholipids.The phospolipids are bipolar in nature.one end of the molecule contains phospherous is polar and hydrophilic(head).The opposite of or tail end is a two fatty acid chain that is non polar and hydrophobic.The tail is directed toward the middle of the membrane and away from the fluid.The heads are found contact with extra and intra cellular fluid.Proteins involved in intracellular signalling can be targeted to plasma membrane and organelles through phospholipid binding domains.thus the phospholipid act as the key in initiating cellular processes

The plasma membrane is composed of both lipids and proteins. The relative concentration of each in the plasma membrane is partly regulated by the A. chromosomes, which dictate the types and number of membrane molecules that are generated B. Golgi complex, which functions in sorting molecules destined for the membrane C. rough endoplasmic reticulum, which functions in the translation of mRNA into membrane proteins D. vacuoles, which transport molecules to the plasma membrane
Question 1. Different types of cells have different types of integral membrane proteins. What would you expect to reside in the plasma membrane of an epithelial cell that might be absent from that of an erythrocyte? How do such differences relate to the activities of these cells? Question 2. In an experiment, let us say you plan to use liposomes in an attempt to deliver drugs to fat or muscle cells. Is there a method in which you might be...
Which of the following is NOT a property of membrane lipids Select one: a. The two leaflets of the plasma membrane have different lipid composition b. Most fatty acids attached to lipids have a length of 16 to 22 carbon atoms c. The plasma membrane is composed of a mixture of glycerolipids, sphingolipids and cholesterol. d. Phospholipids prefer to form micelles e. Cholesterol increases the order of fatty acid side chains
1.A Which of the following substances is made of lipids? enzymes O plasma membrane sugars O DNA
All mammalian cells maintain the resting membrane potential across the plasma membrane. Neurons and muscle cells are capable of generating the action potential to communicate with each other. Below is a diagram showing a temporal change of the membrane potential in axon. Explain how such membrane potential is generated and/or maintained in each stage (1-3). Make sure to identify key membrane proteins and the movement of ion(s) through these membrane proteins in each stage. Calculate the membrane potential at the...
QUESTION 25 Lipids have been shown to move in the membrane. Which statement most accurately describes this movement? Lateral movement of lipids within the same leaflet of the membrane occurs, but is less common, and flip-flop of lipids to the opposite leaflet of the membrane is common Both lateral movement of lipids within the same leaflet of the membrane and flip-flop of lipids to the opposite leaflet of the membrane occur commonly. Lateral movement of lipids within the same leaflet...
1. where would you find the receptor for PTH? on the plasma membrane of target cells on the plasma membrane of all cells in the nucleus of target cells in the cytosol of target cells 2. Where in the parathyroid gland is PTH produced? parafollicular cells or C-cells principal cells oxyphils follicular cells 3. Which hormone is the antagonist to PTH and functions to lower blood calcium levels? calcitriol glucagon calcitonin estrogen
