Which of the following statements best describes the selective permeability of the cell membrane.

. Which of the following statements best describes the selective permeability of the cell membrane. The solubility theory of membrane permeability simply describes that a membrane can only be freely permeable to substances that can dissolve in it. We review their content and use your feedback to keep the quality high.

Permeability of cell membrane refers to the ease with which a molecule can pass through a cell membrane. Which statement best explains the effect on membrane permeability of cholesterol andor temperature. Get 1-on-1 help from an expert tutor now.

Passive membrane permeability is the diffusion of drug across tissue barriers and cell membranes. View the full answer. The cell membrane regulates the transport of intracellular substances out of but not into the cell.

The cell membrane regulates the transport of all substances into and out of the cell. A mixture of covalently linked phospholipids and proteins that determines which solutes can cross the membrane and which cannot. Some of this selective property stems from the intrinsic diffusion rates for different molecules across a membrane.

Which term best describes the plasma membranes structure Lipid bilayer Glycocalyx Phospholipids i Glycoproteins Selective permeability. Which of the following diagrams best represents the resting membrane potential of a neuron. The permeability that a membrane have the right to be identified as the passive diffusion price of permeated molecules across the biomembrane.

Passive diffusion of the glucose through the lipid bilayer. The cell membrane. A fluid structure in which phospholipids and proteins move freely between sides of the membrane.

B The cell membrane regulates the transport of specific substances into and out of the cell. The cell membrane is often thought of as this solid protective border surrounding the cell but really it is designed to be less like a wall and more like a gatekeeper. The cell membrane is selectively permeable meaning it only lets certain things in and out.

Transporting molecules across the cell membrane is one of the important functions of the cell membrane. A the rate at which a molecule crosses the membrane B the ability of a molecule to cross the cell membrane C the surface area of a cell and its relationship to the diffusion of water D whether or not a molecule moves across the cell via passive or active mechanisms. Which of the following best describes the permeability of the cell wall.

Thickness flexibility and amount of molecules do not describe permeability. The answer is D. The cell membrane regulates the transport of intracellular.

It all has to do with the size of the materials trying to pass through. The ability of a molecule to pass through a membrane. It is best described as being selectively permeable.

How does selective permeability help maintain homeostasis. Adding cholesterol reduces permeability because its steroid rings fill gaps in the hydrophobic membrane interior. Which of the following statements best describes the concept of permeability.

The cell membrane regulates the transport of specific substances into and out of the cell. The cell membrane regulates the transport of all substances into and out of the cell. Which best describes the permeability of a membrane.

All other options do not make sense. Lipid bilayer is best term to describe plasma me. The ability of only certain molecules to pass across a membrane.

Cotransport of the glucose with a proton or sodium ion that was pumped across the membrane using the energy of ATP hydrolysis. The need for carrier proteins. It is unanimously welcomed that permeability of any specific molecule depends mostly on fee number polarity size and also to some extent to the molar mass of the molecule.

This was the most basic theory posed to explain. The ability to allow materials to cross a membrane Explanation. Movement of glucose into the cell through a glucose channel.

Which of the following statements best describes the selective permeability of the cell membrane. So this means it is picky or selective about. GIT BBB kidney etc typically feature tight intercellular junctions at the epithelial andor vascular endothelial layers which severely restrict paracellular transfer of molecules.

Is the plasma membrane a fluid or a bilayer. It is the rate at which the passive diffusion occurs through the membrane. The ability to allow materials to cross a membrane.

Facilitated diffusion of the glucose using a carrier protein. Two layers of phospholipids with opposite orientations of the phospholipids in each layer with each layer covered on the outside with. The structure of the phospholipid bilayer prevents random things from drifting through the membrane and proteins act like doors letting the right stuff in and out.
