In actin filament assembly, the process in which ATP-actin monomers are added to the barbed end of the filament while ADP-actin monomers are concurrently dissociating from the pointed end of the filament is referred to as
A) equilibrium.
B) dynamic instability.
C) treadmilling.
D) recycling.

Question

Quizplus · Accepted Answer

This process is known as treadmilling, where new ATP-actin monomers are added at the barbed end while ADP-actin monomers dissociate from the pointed end, resulting in filament growth at one end and shrinkage at the other. Dynamic instability refers to the overall behavior of actin filaments, including both growth and shrinkage phases. Equilibrium and recycling are not accurate descriptions of this specific process.
