SLSC 398 Lecture Notes - Lecture 2: Polyphosphate, Glycan, Cell Membrane
Document Summary
Cell membrane, cell wall structure, and embedded proteins are what determines what goes in and out of the cell. Glycans: 2 alternating sugars, nam and nag. Porins - each subunit is an aqueous channel, it allows passage of smallish dissolved molecules across the outer membrane. Cell membrane = cytoplasmic membrane, and plasma membrane. Selectively permeable: control movement of molecules into and out of cytoplasm. It is driven by protein motive force. Most proteins impart rotational motion of basal structure and connected hook and lament. Flagella can rotate clockwise and counter clockwise. Gas vesicles - it is a thin protein shell excludes water: gas can accumulate.
