5. Actin filaments are incapable of lasting the entire lifetime of the cell.

a) True

b) False

Solution

False

Explanation :- Actin exist in two form inside cell- G actin or globular actin and F actin or filamentous action. G actin polymerize and form a chainlike structure to form F actin. ATP driven polymerization is a continuous process. Inside cell the concentration of G actin and F actin always change due to this process. This process goes on till the death of the cell. So, it can be said that Actin filaments are incapable of lasting the entire lifetime of the cell actin filaments are capable of lasting the entire lifetime of the cell.
