WebThe cell membrane (also known as the plasma membrane ( PM) or cytoplasmic membrane, and historically referred to as the plasmalemma) is a biological membrane that separates and protects the interior of all … Web1 Introduction. Laser-induced periodic surface structures (LIPSS) have been of great interest since they were first reported in 1965, [] as they allow for a direct, quick, and cost effective patterning technique on a wide spectra of materials covering metals, semiconductors, and dielectrics. [LIPSS are classified in two large categories according to the periodicity …

WebChannel proteins provide a hydrophilic channel for polar molecules, such as ions, to travel across the membrane. These are usually involved in facilitated diffusion and osmosis. An example of a channel protein is the potassium ion channel. This channel protein allows the selective passage of potassium ions across the membrane. Web8 nov. 2024 · 1.4: Glycolipids. Last updated.
