The neuron's cell membrane permits some substances to pass through but not others this is because the membrane is?

One of the characteristics of a cell membrane is that it is semi-permeable. As such, it is able to limit what can get into and out of the cell.

What does the outer membrane do?
It is made of phospholipids just as the cell membrane is. There are some differences in the type of proteins embedded in each membrane. Mitochondria have their own DNA and are thought to be another organism that became taken up by a larger cell. Both have benefitted by the relationship.
What happens if the plasma membrane does not work?
Plasma/cell membrane do have a lot of functions. It provides protection and barrier. It identifies and allows certain molecules to go in and out of the cell. Sort of security guard... If plasma membrane stopped working, well, anything can go in and out of the cell, without permisson. Because of this, the cell would be prone to foreign substances. There would be also no balance in the nutrients in the cell.
What process permits absorption of glucose into cells?

What is the advantage of a cell that has a large surface to volume ratio?
The cell might have difficulty supplying nutrients and expelling enough waste products. By remaining small, cells have a higher ratio of surface area to volume and can sustain themselves more easily.
Epithelium that stretches and relaxes?
Transitional Epithelium permits expansion and recoil after stretching without damage. It's found in the urinary bladder, renal pelvis, and ureters. It's called transitional because the appearance of the epithelium changes as stretching occurs.
What is a membrane protein that allows specific charged molecules to pass through from one side of the membrane to another?
A membrane protein that permits the passage of specific substances is selectively permeable. They allow the solvent as specific solutes to pass through.

Why is the plasma membrane called a selectively permeable membrane?
The Plasma Membrane is a selectively permeable membrane as it only allows entry and exit of some selected molecules into and out of the Cells. It also prevents movement of some other materials, therefore the plasma membrane is called a selectively permeable membrane.
What do you understand by terms semi permeable?
A semi-permeable membrane is a membrane that allows certain substances to pass through while preventing others from crossing. It selectively permits the passage of molecules based on size and charge. This property is crucial in biological processes such as osmosis and filtration.
What is a plasma membrane?
A plasm membrane is a permeable memrane located within the cell wall. It serves many functions for the cell, including energy generation and transport of chemicals.
Why a high ratio of surface area to volume benefits a cell?
A high surface area to volume ratio allows the diffusion of water, nutrients, and wastes be more efficient. A higher surface area permits more substances through the cell membrane, and makes the diffusion process more effective and efficient. Hope this helped :)
What contributes to economic and political differences in the states because it permits each state freedom?
permits each state freedom.
Do you have to get your permits first before you get your permits?
Absolutely. You also have to get permits to get your permits to get your permits. That's bureaucracy eh.

What is the area between two neurons?
Area between two neurons is called a synapse.In the nervous system, a synapse is a structure that permits a neuron to pass an electrical or chemical signal to another cell.neurons are cells that are specialized to pass signals to individual target cells, and synapses are the means by which they do so.
Functions of plasma memberane?
Plasma membrane permits the entry and exit of some materials in the cells. Therefore, the plasma membrane is called a selective permeable membrane. Functions of plasma membrane : 1) Diffusion 2) Osmosis 3) Mediated transport
What is a membrane that only allows certain materials to pass through?
A membrane that permits the passage of only certain molecules is called a semi-permeable membrane. In its simplest form, this separation process is based on molecular size. Smaller molecules pass through and larger ones are retained. In most biochemical processes, a concentration gradient drives the movement of molecules through the membrane.
