Final answer:
The statement about neutrophils using actin polymerization and actin-myosin contractions for movement is true. This process mirrors the action of microfilaments in cell motility and muscle contraction in eukaryotes, facilitated by the dynamic polymerization and depolymerization of actin.
Step-by-step explanation:
The statement that neutrophils move via actin polymerization and actin-myosin contractions is True. Neutrophils are a type of phagocytic cell that utilize pseudopodia, formed by the polymerization of actin filaments, to move and engulf particles. This process is akin to the function of microfilaments in various eukaryotic cells. Actin filaments interact with motor proteins, such as myosin, allowing for cellular movement. For example, in muscle cells, actin and myosin interaction is fundamental for muscle contraction, operating under the sliding filament model.
More broadly, the dynamic nature of actin microfilaments enables them to polymerize and depolymerize in response to cellular signals, playing a critical role in cell motility and other cellular activities needing motion, such as cell division and cytoplasmic streaming.
