A patient has had a serious accident and lost a lot of blood. In an attempt to replenish body fluids, distilled water, equal to the volume of blood lost, is transferred directly into one of his veins. The patient’s red blood cells will swell because the blood fluid is hypotonic compared to the cells.

Example: Plants use the mechanism of sucrose/H+ cotransport to load sucrose produced by photosynthesis into specialized cells in the veins of leaves. Transport proteins can move sucrose into the cell against the concentration gradient only if it travels with the H+ ion.

What will be the most probable result of this transfusion? The patient’s red blood cells will swell and possibly burst because the blood has become hypotonic compared to the cells.

Question: Glycoproteins And Glycolipids Of Animal Cell Membranes Are Most Important For Maintaining The Integrity Of A Fluid Mosaic Membrane Active Transport Of Molecules Against Their Concentration Gradients The Ability Of Cells To Recognize Other Cells Facilitated Diffusion Of Molecules Down Their Concentration …

Transportation. Membrane proteins can allow hydrophilic molecules to pass through the cell membrane. Transport membrane proteins come in many forms, and some require energy to change shape and actively move molecules and other substances across the cell membrane. They do this by releasing ATP to use as an energy source …

The proteins in the plasma membrane typically help the cell interact with its environment. Many proteins can move within the plasma membrane through a process called membrane diffusion. This concept of membrane-bound proteins that can travel within the membrane is called the fluid-mosaic model of the cell membrane.

Why is it important that there are different types of proteins in plasma membranes for the transport of materials into and out of a cell? The proteins allow a cell to select what compound will be transported, meeting the needs of the cell and not bringing in anything else.

The correct answer is E) store cellular nutrients. Cell membrane proteins cannot store cellular nutrients as they are far too small and located in an inconvenient location to actually distribute these nutrients throughout the cell.

Glycolipids :Glycolipids are found on the surface of the cell membranes. Cholesterol in plasma membrane play a role in structure and function of plasma membrane. Therefore, it has been clear from the above discussion that Lignin is not present in the cell membrane. Hence, option C is the correct answer.

All that’s true but protein also serves another critical function in the body: It helps power your immune system, stoking the cells that you need to fight off infection, both bacterial and viral, and keep your guard up against illness of all kinds.

In general, your body fights disease by keeping things out of your body that are foreign. Your primary defense against pathogenic germs are physical barriers like your skin. You also produce pathogen-destroying chemicals, like lysozyme, found on parts of your body without skin, including your tears and mucus membranes.

A person with a weak immune system may be more prone to frequent infections. White blood cells, antibodies, and other components, including organs and lymph nodes, make up the body’s immune system. Many disorders can weaken the immune system and cause a person to become immunocompromised.
