Solutions.
cell membrane correct answers the semipermeable membrane surrounding the cytoplasm of a
cell. Borders between the cell contents and the extracellular fluid
cell membrane separates what? correct answers cell membrane separates living from non-living
surroundings. It is a thin barrier (6-10nm) thick. Controls what goes into and out of the cell.
cell membrane are what? correct answers cell membrane are selectively permeable meaning it
allows some substances to cross more easily than others. Hydrophobic and hydrophilic
Cell membrane is made of correct answers phospholipids
proteins
other macromolecules
Hydrophobic correct answers Water fearing
Hydrophilic correct answers water loving
Macromolecules correct answers large molecules
biological membranes correct answers biological membranes are high organised structures and
highly selective permeability barrier. Almost the whole cell pathology is a result of the damage
the cell
the effect of great variety of medicine is owing the membrane what? correct answers the effect of
great variety of medicines is owing to membrane stabilisation, receptor interaction or trans
membrane transport regulations
physical methods of using cell membranes correct answers electron microscope and x ray
strcture analysis. They're used to investigate structure and main features of the biological
membranes
membrane correct answers Membrane is an organised arrangement of lipids and proteins that
enclose and separates the cell from its surroundings. Membranes define spaces with distinctive
character and function
, Example of Cell Membrane correct answers cytoplasm
nucleus
example of specialised membranes correct answers myelin
photoreceptor
native membrane correct answers Native membranes are completely saved membranes in
structurally and functionally attitude
modified membranes correct answers Modified membranes have a changed structure and
function for in vitro experimental conditions
example of artificial membrane correct answers lipids
proteins
lipid monolayer, bilayer
reconstructed membrane correct answers reconstructed membranes have a self organisation of
fragments from natural membranes or of isolated from lipids and proteins
membrane functions correct answers 1) transport of substances
2) energy transfer
3) identification of molecules and cells
4) generation and amplification of signals
5) restriction and division
energy transport (membran) correct answers photosynthesis
identification of molecules and cells (membrane) correct answers cell to cell organisation
generation and amplification of signals (membrane) correct answers cell excitation and potential
propagation
transport of substances (membrane) correct answers the membrane is highly qualified barrier
with specific transport systems such as pumps and channels
restriction and division (membrane) correct answers compartmentation of the cell dissociate
cytoplasm from the surroundings and determine its individuality
functions of cell membrane correct answers cell to cell communication
signal detection
transport
localise specific functions
boundaries
cell to cell adhesion
common features of biological membranes correct answers 2 molecules of thickness (6-10nm)
