Final answer:
The names given are motor proteins and protein monomers, which work together with the cell's cytoskeletal structures, microtubules, and microfilaments, to maintain cell shape and facilitate movement.
Step-by-step explanation:
Actin, dyneins, kinesins, myosin, and tubulin are the names of motor proteins and structural protein monomers; microtubules and microfilaments are the names of components of the cytoskeleton, made of different types of proteins.
Microtubules are composed of tubulin dimers, specifically alpha-tubulin and beta-tubulin, which form hollow tubes important for cell shape and intracellular movement. Microtubules work with motor proteins like dynein and kinesin to transport organelles and vesicles within the cell. They are also crucial for the structure of cilia and flagella, contributing to cell motility.
Microfilaments are thinner than microtubules and consist of actin monomers that form two intertwined strands. They play a significant role in cellular movement, especially muscle contraction, where actin and myosin interact. This infrastructure is essential for maintaining cell shape and enabling cell motility.
