Cofilin:
A)cleaves actin by binding the ATP-actin in the filament.
B)cleaves actin by twisting adjacent F-actin monomers in the filament.
C)recruits G-actin monomers to the elongating F-actin microfilament.
D)promotes exchange of ADP for ATP on G actin.

Question

Quizplus · Accepted Answer

Cofilin works by binding to F-actin monomers and twisting them, causing the actin filament to break and destabilize. This allows for faster turnover of actin filaments and aids in cell movement and shape changes. It does not recruit G-actin monomers or promote exchange of ADP for ATP on G-actin.
