Internal
Organization
of the cell
- Membrane Structure
- Plasma membrane
- Encloses cell, defines
its boundaries and
maintains the essencial
differences between
cytosol and
extracellular
environment
- Eucaryotic cells,
membranes, endoplasmic
reticulum, golgi apparatus,
mitochondria,
membrane-enclosed
- 4 phospholipids
- phosphatidylcholine
- phosphatidylethanolamine
- phosphatidylserine
- Translocation in
apoptotic cell by
two mechanism
- The
phospholipid
translocator is
inactivated
- Scramblase that transfer
phospholipids in both
directions is activared
- The
phospholipid
translocator is
inactivated
- Translocation in
apoptotic cell by
two mechanism
- sphingomyelin
- phosphatidylcholine
- 4 phospholipids
- Encloses cell, defines
its boundaries and
maintains the essencial
differences between
cytosol and
extracellular
environment
- Ion gradients
- Across membrane, activities
of membrane proteins,
synthesize ATP, movement of
selected solute,produce
electrical signals
- Across membrane, activities

- thin film of lipid and
protein molecules held by
noncovalent interactions
- Lipid Bilayer
- Fluid structure,
impermeable barrier to
water-solube molecules
- Lipid
Molecules
- Amphipathics that
have hydrophilic end
and a hydrophobic end
- Phospholipids
- Have a polar head
group and two
hydrophobic
hydrocarbon tails
- phospholipases
- activated by
extracellular
signals to
cleave
phospholipid
