Membrane Mechanics of Endocytosis in Cells with Turgor - Fig 1

<p>Left: schematic representation of endocytosis. The membrane is connected mechanically to the actin network through sla2. Actin is polymerizing close to the basal membrane, thus generating an upwards (pulling) force <i>f</i>_<i>a</i>. This force overcomes the rigidity <i>κ</i>, tension <i>σ</i> and the turgor pressure Π that all oppose invaginations. Right: four experimental membrane profiles at different stages, measured in an electron-microscopy study [<a href="http://www.ploscompbiol.org/article/info:doi/10.1371/journal.pcbi.1004538#pcbi.1004538.ref008" target="_blank">8</a>]. Scale bar: 20<i>nm</i>.
