The thick filament is composed of the myosin molecule. The thin filament is composed of the actin molecule. Flexing the head of myosin provides the powerstroke.

What are cytoskeleton filaments built of?
The cytoskeleton is made up of three kinds of protein filaments:Actin filaments (also called microfilaments)Intermediate filaments andMicrotubules
What maintains the cell shape anchors the organelles in place and moves organelles of the cell?
Cytoskeleton
Cilia and flagella are made of protein filaments called?
Cilia and flagella are made of dynins and nexin proteins. Cilia and flagella are made up of microtubules and they are long, wispy tentecles that resemble hair.
Fine branching protein fibers that construct a supportive network?
It is the cytoskeleton. It is made of proteins
Actin makes up cytoskeleton fibers called?
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
The thick filaments of muscle fibers are composed of what?
Myosin
Is it true that thick filaments are made of a protein called actin?
false, it's made of myosin
What are actin and myosin and are they organized iin a muscle?
Thick filaments are made of the protein myosin and thin filaments are made of the protein actin. Myosin and actin filaments are arranged to form and overlapping pattern which gives muscle tissue its striated appearance.
What are cytoskeleton filaments built of?
The cytoskeleton is made up of three kinds of protein filaments:Actin filaments (also called microfilaments)Intermediate filaments andMicrotubules
What makes up a myofibril?
Myofibrils are made up of actin (thin filaments) and myosin (thick filaments).
Does cells have cytoskeletons made of bone?
No, cytoskeletons are made of protein filaments
Cytoplasmic streaming visible in the elodea cells?
Myosin (thick filaments made of protein) attached to organelles in the fluid cytosol (the streaming part of the cytoplasm) drive cytoplasmic streaming by interacting with the carpet of parallel actin filaments present within the cytosol.
Do smooth muscle have thick and thin filament?
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.
What is a muscle made from?
A muscle is made of many cylindrical muscle fibers. The many fibers are bound together with connective tissue. Nerves and blood vessels (arteries and veins) run along the connective tissue.In every muscle fiber, there are thick filaments, made of the protein myosin, and thin filaments, made of the protein actin. The filaments overlap to form the sarcomere, a part of the muscle. Myosin has little heads that attach to actin, and pull on it. This is when the sarcomere contracts, and when all of the sarcomeres of a muscle contract, the entire muscle contracts.

The larger of the two filaments forming a cross-bridge is made of a protein called?
Myosin
What are the two types of myofilaments?
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)
