membrane carbohydrates are used for the selection of cells to make tissues, and the rejection of foreign cells (like in your blood).
Cells recognize each other by binding to surface molecules, often carbohydrates, on the plasma membrane.
Membrane carbohydrates may be covalently bonded to lipids of more commonly proteins (forming glycoproteins).
Carbohydrates on the external side of the plasma membrane vary among species, individuals, and even cell types in an individual

What is a model used to explain the components and properties of a plasma membrane?
The fluid mosaic model is commonly used to explain the structure and function of the plasma membrane. It describes the membrane as a fluid lipid bilayer with embedded proteins that can move laterally, giving the membrane its dynamic nature. The model helps illustrate how the plasma membrane controls the passage of substances into and out of the cell.
Explain the structure of the fluid mosaic model?
The cell membrane is made up of a variety of molecules including phospholipids, proteins, sugars, and other various building blocks. Fluid mosaic refers to the ability of these elements to shift about the cell membrane, which is ever-changing. Much of the ability to shift comes from the unsaturated lipid chains in the cell membrane, which have kinked structures that prevent the phospholipids of which they are a part from packing tightly together. The fluidity of the membrane is essential for some small molecule transfer between the inside and outside of a cell, as well as the activation of some important pathways which require molecules embedded within the cell membrane to either split or join.
What are two main components of cellular membranes?
Partially permeable , permeable , immpermeable .
What are the limitations of the Davson-Danielli model of membrane structure?
The Davson-Danielli model of membrane structure is limited because it suggests that membranes are made of a simple sandwich-like structure, which does not account for the dynamic nature of cell membranes and the presence of integral membrane proteins. This model also fails to explain how membranes can selectively allow certain substances to pass through while blocking others.
What physical property of the dialysis tubing might explain its differential permeability?
Dialysis tubing is an impermeable membrane/containment vessel that is stratified with microscopic holes which restrict certain molecules or particles from diffusing through them. This leads dialysis tubing to serve as a selectively permeable membrane because it selectively prevents certain molecules from crossing the membrane based on the size of the molecules. (Typically water and glucose will diffuse through, whereas starch and potassium iodide will not.
Explain in detail the process of digestion and abosortion of carbohydrates?
explain digestion of carbohydrates
What model is used to explain the componets and properties of plasma membrane?
The Fluid Mosaic Model is used to explain the components and properties of the plasma membrane. This model describes the plasma membrane as a dynamic structure composed of a lipid bilayer with embedded proteins that can move and interact within the membrane.
Explain the meaning the first shall be last.?
Those who are given much recognition on earth will be of less importance in heaven. and those who are given least recognition will have greater recognition in heaven.
What are the main nutrients found in bread explain?
vitamin carbohydrates proteins
Welcome address for recognition day?
A welcome address for a recognition day would first greet the people that were in attendance. After that it would explain the reason for the recognitions.
Explain how carbohydrates relate to the food pyramid?
Carbohydrates relate to the food pyramid because they give us energy to do work. Carbohydrates are in grains, pasta, bread, wheat and oats listed in the pyramid.

Explain the function of the cell membrane?
The plasma membrane separates the cell from its' surrounding environment and is arranged in a bilayer sheet of phospholipids. It is a mosaic of molecules in a fluid. That is, the molecules are able to float around slowly (like islands in the sea). The cholesterol molecules are scattered among the phospholipids to allow the membrane to function properly at body temperature. Most of the bilayer is hydrophobic; therefore water or water-soluble molecules do not pass through easily. A cell controls what moves through the membrane by means of membrane proteins embedded in the phospholipid bilayer. Some membrane proteins have carbohydrates attached to them, forming glycoproteins that act as identification markers.
What is cell membrane explain in urdu?
plasma membrane is the outer most boundary of animal cell.it is chemically composed of lipids and proteins.it is selectively permeable allow certain materials to move in and out.fluid mosaic modle explain its structure.
The is a model used to explain the components and properties of a plasma membrane?
Fluid-mosaic model
Explain how a tree and fox get carbohydrates to use for energy?
Trees and other plants reserve a small fraction of oxygen produced from photosynthesis to convert their carbohydrates into energy. This differs from animals who eat food to obtain carbohydrates.
What foods from the four food groups or the food pyramid would provide a balanced meal. explain?
starch fat and carbohydrates
