Final answer:
Microfilament assembly and disassembly are dependent upon the concentration of actin monomers. These monomers utilize ATP to transition between states, which is critical for cellular processes like motility and muscle contraction.
Microfilament assembly and disassembly are dependent upon the concentration of actin monomers
so the correct answer is Option C
Step-by-step explanation:
The concentration of actin monomers is dependent upon the assembly and disassembly of microfilaments. These monomers bind ATP to polymerize into filamentous actin (F-actin), which then forms the microfilament structures crucial for various cellular processes. ATP hydrolyzes to ADP on the actin monomer, which causes a change in its binding strength and subsequently affects the stability of the filament. The constant turnover of ATP to ADP and vice versa on the actin monomers facilitates the dynamic nature of microfilament assembly and disassembly, essential in cellular motility and muscle contraction.
the correct answer is Option C
