Ftsz is a bacterial cytoskeletal protein that forms a contractile ring involved in bacterial cytokinesis. its function is analog
natita [175]

The function of the FtsZ is analogous to the cleavage furrow of the cells of eukaryotes of an animal. This is a protein encoded by the gene FtsZ in which this protein has the capability of producing a new cell wall that is in between the dividing cells.

The type of contraction in which the muscle fibers do not shorten is called
Korolek [52]

Answer:

Isometric contraction

Explanation:

The length of the muscle is changed during contraction only when the muscle tension during contraction can outstand the resistance exerted by the object to be lifted.  

During isometric contractions, the muscle tension is not sufficient to exceed the resistance of the object. Hence, there is no change in the length of the muscle. The isometric contraction does not bring about any body movements.

after a power stroke, the myosin head must detach from acting before another powerstroke can occur. what causes
kompoz [17]

The myosin head separates from actin as a result of ATP binding. The intrinsic ATPase activity of myosin then transforms ATP into ADP and Pi. The myosin head's angle is altered into a cocked state by the energy generated during ATP hydrolysis. The myosin head is now ready to move in the future.

The myosin protein is in a high-energy conformation when the head is cocked. At the end of the power stroke, the myosin head is in a low-energy position because this energy has been used up during the power stroke. ADP is released following the power stroke, but the cross-bridge is still there and actin and myosin are joined together.

Since ATP is readily available, the cross-bridge cycle can repeat, and muscular contraction can go on as long as ATP is there.
