Microfilaments (in cytoskeleton) and thin filaments (in muscle cells) are both polymers of actin.
Microfilaments are made from a protein called actin. Actin filaments are composed of monomers of globular actin proteins, which can polymerize to form long, thin filaments that are a crucial component of the cytoskeleton in cells.
A microfilament is a small filamentous structure found in cells, made up of actin protein subunits. Microfilaments are involved in various cellular processes such as cell movement, cytokinesis, and maintenance of cell shape. They are part of the cytoskeleton, which provides structural support to the cell.
The actin that makes up cytoskeleton fibers are called microfilaments. They are the thinnest filaments of the cytoskeleton a structure found in the cytoplasm of eukaryotic cells.Ê
Yes, myofibrils are made up of repeating units called sarcomeres, which contain protein polymers called actin and myosin. These filaments slide past each other during muscle contraction, allowing for muscle movement. The arrangement of these proteins within the myofibrils gives muscles their striated appearance.
Actin and microtubules are distinct structures within the cell. Actin is a protein that forms thin filaments, while microtubules are made of tubulin proteins and form a network of hollow tubes. Both actin and microtubules play important roles in cell structure and movement.

The ball-shaped protein called actin is the primary component of microfilaments. Actin molecules polymerize to form thin, flexible filaments that are important for cell movement, shape, and division.
Microfilaments are made of protein strands called actin.
false, it's made of myosin

The thin myofilament of skeletal muscles is made of the globular protein called actin.
Muscle fibres contain two myofilaments called actin and myosin
Microfilaments assist with cell movement and are made of a protein called actin. Actin works with another protein called myosin to produce muscle movements, cell division, and cytoplasmic streaming. Microfilaments keep organelles in place within the cell.
The two filaments involved are myosin and actin. Actin: is the framework and slides over the myosin filament when the muscle is shortened. myosin: is a thick filament Also a sacromere: is made up of the actin and myosin. It is the functional unit of a muscle fibre and extends from z line to z line. A muscle contraction: is many sacromeres shortening ( actin sliding over myosin)
Both do have actin and myosin.Within each skeletal muscle fiber are hundreds of lengthwise subdivisions called myofibrils.Myofibrils are made up of bundles of the protein filaments (myofilaments) that are responsible for muscle contraction: thin filaments: made of the protein actin, andthick filaments: made of the protein myosin.These are visible using a microscope.The internal organization of actin and myosin in smooth muscle is different from that in the striated muscles.Smooth muscle cells: are long and slender, are spindle shaped, with a single, central nucleus, have scattered myosin fibers, with more heads per thick filament and have actin filaments attached to dense bodies.These can not be seen using a microscope and that is why they are also called smooth muscle fibers.
