Discuss the various functions of membranes and identify the membrane components

Question

Discuss the various functions of membranes and identify the membrane components (i.e. lipids or proteins) that are associated with each function Describe the evidence that is inconsistent with early models of the cell membrane which suggested the presence of protein layers on the extracellular and cytosolic sides of the membrane Describe the key features of the fluid mosaic model Discuss the different ways in which lipids move within membranes, discussing the relative frequency of such movements and ways in which cells regulate thermodynamically unfavorable lipid movements Discuss the various functions of membranes and identify the membrane components (i.e. lipids or proteins) that are associated with each function Describe the evidence that is inconsistent with early models of the cell membrane which suggested the presence of protein layers on the extracellular and cytosolic sides of the membrane Describe the key features of the fluid mosaic model Discuss the different ways in which lipids move within membranes, discussing the relative frequency of such movements and ways in which cells regulate thermodynamically unfavorable lipid movements Discuss the various functions of membranes and identify the membrane components (i.e. lipids or proteins) that are associated with each function Describe the evidence that is inconsistent with early models of the cell membrane which suggested the presence of protein layers on the extracellular and cytosolic sides of the membrane Describe the key features of the fluid mosaic model Discuss the different ways in which lipids move within membranes, discussing the relative frequency of such movements and ways in which cells regulate thermodynamically unfavorable lipid movements

Explanation / Answer

Biological membrane are helpful to maintain structure of cell and play function of transport of molecule.

Membrane like plasma membrane is made up of phospholipids. The model of fluid mosaic plasma membrane gives detail structure and functional activity of membrane.

According to this modal the protein molecule are embeded in lipid bilayer which is looking like floating bubbles.

In this membrane intrinsic and exterinsic protein are present and channel protein also present which are help in signaling and transporting.

Many experimental evidence are performed and found by some experiment one of them is Robertson unit membrane model experiment.
