Biology F211 Cells Part 2
Biological membranes - fluid boundaries
Roles of membranes
Separating cell contents from the outside environment
Separating cell components from the cell cyoplasm
Cell recognition and signalling
Holding the components of some metabolic pathways in place
Regulating the transport of materials into or out of cells
A phospholipid molecule has a hydrophillic head and a hydrophobic tail
These properties come from the way charges are distributed across the molecule
If phospholipid molecules are completely surrounded by water, a bilayer can form
The basic structural component of all biological membranes
Specialisation of cell surface membranes
Plasma membranes of the cells in a growing shoot contain receptors that allow them to detect the molecules that regulate growth
Muscle cell membranes contain a large number of channels that allow rapid uptake of glucose to provide energy for muscle contraction
The internal membranes of chloroplasts contain chlorophyll and other molecules needed for photosynthesis
The plasma membranes of white blood cells contain special proteins that enable the cell to recognise foreign cells and particles
All membranes are permeable to water molecules because water molecules can diffuse through the bilayer
The fluid mosaic model
Communication and cell signalling
Crossing membranes 1 - passive processes
Crossing membranes 2 - active processes
Water is a special case
