Biophysique FTM 2 Comprehensive Questions
(Frequently Tested) with Verified Answers Graded
3 components of cytoskeleton - ANSWERactin filaments (microfilaments),
intermediate filaments, and microtubules
functions of cytoskeleton - ANSWERStructural support and stability
Organization
cell division
cell movement
Tracks for motor proteins to move organelles and vesicles within cells
Microtubules function - ANSWERIntracellular transport- helps movement of
vesicle and organelles using motor proteins like kinesin and dyenin.
Cell motility- movement of cilia and flagella via motor proteins; cell
elongation and movement
Mitotic spindle- attachment of chromosomes and their movement during cell
division
Rigid intracellular skeleton- maintains cell shape and polarity
It assembles and disassembles per the cell needs
structure of microtubules - ANSWERnon-branching, rigid, hollow tubes made
of alpha and beta protein subunits.
It is polar -end and +end
, Centrioles structure - ANSWER9 triplets of microtubules arranges around
central axis
each triplet has 1 complete 2 incomplete microtubules fused
centrioles function - ANSWEROrganize the centrosome
formation of basal body which are necessary for cilia and flagella
it helps with centrosome formation and alignment of mitotic spindle during
cell division
Centrosome - ANSWERmicrotubule organizing center
it contains a pair of centrioles (one perpendicular to other)
contains gamma tubulin ring complexes that serve as nucleation sites for
microtubules
Function of centrosome - ANSWEROrganizes microtubules; starts the
microtubules formation- microtubules nucleate/degrade at the - end and
polymerize at + end facing the cell periphery
What organizes polymerization of microtubules - ANSWERMTOC
what is polymerization of microtubules dependent on ? - ANSWERgtp
dependent
Microtubule-associated proteins (MAPs) - ANSWERCross-linking proteins that
stabilize bundles of permanent microtubules (e.g. the microtubules that run
the length of nerve axons) by binding to the sides of the microtubules.
