Definition of plasmalemma – a plasma membrane which bounds a cell, especially one immediately within the wall of a plant cell. It consists of a lipid bilayer with embedded proteins. See Words from the same year. The lipids and proteins are present in varying proportions of 1:- 1:3.

It is sempermeable and conducts . The cell membrane is also known as plasmalemma and provides a layer of protection to hold the cell contents in. Forum discussions with the word(s) plasmalemma in the title: No titles with the word(s) plasmalemma. Help WordReference: Ask in the forums yourself.

The plasmalemma is composed of proteins, lipids, glycolipids, and carbohydrates.

Lipid forms about of the mass of the plasmalemma and consists of three major classes of lipid: phospholipids, glycolipids, and cholesterol. Of these phospholipids are the most abundant. Four major types of phospholipid have been . The fibronectin receptor belongs to a class of proteins, the integrins. Whereas the morphological appearance of the tonoplast follows that .

If one looked closely at an individual muscle fiber, one would see that it is surrounded by a plasma membrane, called the plasmalemma (figure ). The sarcolemma is composed of the plasmalemma and the basement membrane. Es stößt als äußere Struktur der lebenden Zelle an die unbelebte Zellwand. Universeel: alle cellen zijn minimaal omgeven door een plasmalemma.

Per type organisme: aangevuld of verstevigd me groepsspecifieke componenten. Primaire-secundaie celwand met cellulose als hoofdbestanddeel bij PLANTEN. Met peptidoglycanen en-of sachariden verstevigde celwand bij BACTERIA.

Endothelial subcellular structures, including caveolae, fenestrae and transendothelial channels, are crucial for regulating microvascular function. Aikawa M, Miller LH, Rabbege J. General characteristics of alkaline phosphatase activity of the plasma membrane-enriched fraction isolated from rat mesenteric arteries were investigated. The vascular smooth muscle plasmalemma alkaline phosphatase is a metalloenzyme which is strongly inhibited by chelating agents and this inhibition can be . Evidence for the role of the plasmalemma in metal tolerance of metal resistant ecotypes, cultivars and clones is presented. A range of tolerance mechanisms involving the plasmalemma are discussed including alterations to protein carrier and channel function and synthesis, efflux pumps and maintenance of .

In recent years there has been an increasing tendency to regard the tono- plast as the decisive diffusion barrier of the protoplast. Brooks Arisz Epstein Briggs and Robertson Sutcliffe 12). This view is, however, based on . Electron transport has now been established to occur not only in membranes of chloroplasts or mitochondria but also in the plasma membranes of prokaryotes and eukaryotes. Here the basis reactions and reaction participants of electron transport in the plasma membrane of plant cells – the plasmalemma – are reviewed .
