What are actin fibers?
Actin is a contractile protein fibers present in muscles.It occurs in two forms a.monomeric G actin b. polymeric F ACTIN.
Are posix threads user level or kernel level?
POSIX threads are user level threads, because had a interface library and the operating systems don't control his ejecution and does not know
What material are microtubules composed of?
Microtubules are polymers of tubulin. Microfilaments are polymers of actin.
Why does fabric shrink?
Cloth is made of woven together threads, which are made up of cotton fibers. As the fibers are spun into thread, the thread is woven into cloth, the fibers get stretched. The stress of them being stretched is relieved when they are washed.
What does myosin attach to?
During muscle contraction, myosin cross bridges attach to active sites of ACTIN FILAMENTS.
Long threads made of actin are called?
Microfilaments (in cytoskeleton) and thin filaments (in muscle cells) are both polymers of actin.
What is a microfilament?
Being part of the cytoskeleton, microfilaments allow cells to move.
Microfilaments are made from a ball shaped protein called?
Actin
Is bacteria round or made from long threads?
Fungi
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)
What is a myofibril made up of?
Actin, myosin
Muscle cells are made up of?
actin
What are sacromer made up of?
Actin and Myosin
Myofibrils are made primarily of what?
actin and myosin
A unit of muscle that is made of actin and myosin?
Sarcomeres contain myofilaments which consist of actin (thin) and Myosin (thick).
What are microtubes made out of?
Microfilaments are made of protein strands called actin.
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.
