Peripheral membrane proteins do not interact with the non-polar region of the cell membrane. Instead, they are bound to the cell membrane through interactions between the polar region of the phospholipids and the polar region of the protein. Many peripheral membrane proteins bind to integral membran...
Specific epithelial cell location depends on the type. For example: Simple squamous: These cells form a thin, single layer that creates a membrane. They are found in the walls of your capillaries, along the linings of the alveoli in yourlungs, and in the linings of the pericardium. ...
The cell membrane is sometimes also referred to as the plasma membrane. Cell membranes are based on a framework of fat-based molecules called phospholipids, which physically prevent water-loving, or hydrophilic, substances from entering or escaping the cell. These membranes are also studded with ...
How does trimebutine work?Trimebutine acts directly on smooth muscle by preventing the influx of extracellular calcium ions into smooth muscle cells and the release of calcium from intracellular calcium stores. This results in depolarization of the cell membrane and decreases peristalsis (the wave-like...
In this lesson, we'll discuss the structure of the cell membrane and how this influences diffusion. Then, we'll give three examples of substances...
