What are non motile bacteria?
Non-motile bacteria are ones that cannot move on their own accord. Many kinds of bacteria can move using flagella, axial filaments or can glide by producing slime. But non-motile ones can't move themselves.
What are the types of filaments found in eukaryotes?
The types of filaments found in eukaryotic cells are actin filaments (microfilaments), intermediate filaments, and microtubules. Actin filaments are involved in cell movement and structure, intermediate filaments provide mechanical support to the cell, and microtubules are important for cell division and intracellular transport.
Which of the following become connected by myosin cross-bridges during muscle contraction A) thin filaments and thick filaments B) thin filaments and t-tubules C) thick filaments and titin filame?
Interactions between actin and myosin filaments of the sarcomere are responsible for muscle contractions. The I bands contain only thin (actin) filaments, whereas the A bands contain thick (myosin) filaments.
What is The internal skeleton of a cell is composed of?
Microtubules, Intermediate Filaments, and M icrofilaments
How is the H band distinguished from the other prominent structural features of the sarcomere?
The H band is located at the center of the A band in the sarcomere and is where only thick filaments (myosin) are present, with no overlap with thin filaments (actin). It appears lighter under a microscope due to the organization of filaments. This region shortens during muscle contraction as the myosin filaments slide past the actin filaments towards the M line.
What is the difference between flagella and axial filaments?
* the flagella is a project as strand while the axial filaments are spirochetes. * flagella : move cell by propeller like action , axial filaments : snake-like movement. flagella : present in gram (+)and gram (-) , while the filaments only in gram (-) . both of them have the same function
How does spirochetes move?
A spirochete can move by rotating its axial filaments.
What is a Blepharoplast?
A cylindrical basal body of flagellates that is composed of parallel peripheral rods connected to the axial filaments of flagella or cilia.
What is blepharoplast?
A cylindrical basal body of flagellates that is composed of parallel peripheral rods connected to the axial filaments of flagella or cilia.
Do myosin filaments outnumber actin filaments in skeletal muscles?
No, actin filaments outnumber myosin filaments in skeletal muscles. Actin filaments are thin filaments, while myosin filaments are thick filaments. The arrangement and interplay of these filaments during muscle contractions are essential for movement.
Is the vertebra axial or appendicular?
It is axial.
Myofibrils are composed primarily of two protein filaments called?
thick filaments and thin filaments
What are cytoskeleton filaments?
Cytoskeleton filaments are protein fibers within cells that provide structure, support, and facilitate cell movement. They include microfilaments (actin filaments), microtubules, and intermediate filaments. These filaments help with cell division, cell shape maintenance, and cell signaling.
What are non motile bacteria?
Non-motile bacteria are ones that cannot move on their own accord. Many kinds of bacteria can move using flagella, axial filaments or can glide by producing slime. But non-motile ones can't move themselves.
What are the 3 types of filaments within a muscle and what protein makes up each filament?
The three types of filaments within a muscle are thin filaments, thick filaments, and elastic filaments. Thin filaments are primarily composed of the protein actin, while thick filaments are made up of myosin. Elastic filaments, which help maintain the structure and elasticity of the muscle, are primarily composed of the protein titin. These filaments work together to facilitate muscle contraction and relaxation.
Are there more thick filaments than thin filaments in smooth muscle?
There more thin filaments than thick filaments in smooth muscle. The ratio is of the thin to thick filaments in the smooth muscle is approximately 15:1.
What is axial thrust?
Axial Thrust is a force that is generated in an axial direction which is by definition along the shaft
