If the concentration of free subunits is C, under which condition does the growth of a cytoskeletal filament proceed spontaneously? A) C 1/kₒn B) C kₒn/kₒff D) C kₒff/kₒn E) C Cc×kₒn/kₒff

Question

If the concentration of free subunits is C, under which condition does the growth of a cytoskeletal filament proceed spontaneously?
A) C > 1/kₒn
B) C < 1/kₒff
C) C > kₒn/kₒff
D) C > kₒff/kₒn
E) C > Cc×kₒn/kₒff

Quizplus · Accepted Answer

Cc = kₒff/kₒn. At concentrations of monomers C > Cc, the free-energy change for polymerization is negative and growth can proceed spontaneously.
