What are the contractile protein of muscle?
Actin and Myosin
What is composed of myosin protein?
thick filaments
Myofibrils are constructed of overlapping strands of protein polymers?
Actin and Myosin. A conglomeration of actin fibrils and myosin filaments form a myofibril body called a sarcomere.
What is the contractile ring in mitosis made up of?
Microfilaments form the ring in cytokinesis of animal cell division.
what is the role of microfilaments?
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.
What are the two contractile proteins of muscle?
The two types of protein that are in your muscle cells are actin and myosin. What they do is they slide past each other and that makes a muscle cell work.
Which mechanism involves the drawing of actin microfilaments between myosin microfilaments?
The ratchet mechanism
What protein allows muscle cells to expand contract?
There are three types of proteins in the muscle; contractile, regulatory, and structural. Contractile: Myosin and actin. Regulatory: tropomyosin and torponin. Structural: Titin, alpha-actin, Myomesin, Nebulin, and Dystrophin.
Are the two contractile proteins in muscles myosin and actin?
Yes the contractile proteins generate force during contraction and are actin and myosin
What are microfilaments responsible for?
Microfilaments assist with cell movement and also works with another protein called myosin to produce muscle movements, cell division, and cytoplasmic streaming. They also help to hold organelles in place.
What are 3 protein fibers found in cytoskeleton?
1. A network of microtubules mainly in ectoplasm2. cytoplasmic network of microfilaments (actin filaments)3. Intermidiate fillamentsthe main protein of cytoskeleton are tubulin, actin, and myosin.
Contractile elements of muscle cells are?
actin myosin
