Myosin is a protein primarily found in muscle cells. It plays a key role in muscle contraction by interacting with actin filaments to generate movement. Myosin is also found in other cell types where it has various functions related to cellular movement and transport.

Are myosin filaments located in an A band?
Yes, myosin filaments are found in the A band of a sarcomere, which is a structural unit of a muscle cell. The A band contains both myosin and actin filaments and is located in the middle of the sarcomere.
Is actin and myosin a carbohydrate?
No, actin and myosin are not carbohydrates. They are proteins involved in muscle contraction.
What is a myofibril made up of?
A myofibril is made up of repeating units called sarcomeres. Sarcomeres contain thick and thin filaments that slide past each other during muscle contraction. The protein fibers actin and myosin make up the thin and thick filaments, respectively.
Which event causes cross bridge detachment?
The binding of ATP to the myosin head causes cross bridge detachment by disrupting the binding between myosin and actin. ATP provides the energy necessary for myosin to release from actin and reset for the next contraction cycle.
Do Sarcomeres produce actin and myosin?
Sarcomeres do not produce actin and myosin. Actin and myosin are protein filaments that are found within sarcomeres and are responsible for muscle contraction. Sarcomeres contain organized arrangements of actin and myosin filaments that slide past each other during muscle contraction.
The thick filaments of muscle fibers are composed of what?
Myosin
What are the thick protein filaments in the cell made of?
The thick protein filaments in a cell are primarily made of a protein called myosin. Myosin filaments are involved in muscle contraction and various other cellular processes such as cell motility and cytokinesis.
What are Thick myofilaments are made of?
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)
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 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 Every muscle is made of a particular type of?
Myosin
Is it true that thick filaments are made of a protein called actin?
false, it's made of myosin
What are the proteins are involved in muscle contraction?
Actin and myosin
What protein makes up the thick filaments of myofibrils?
Myosin makes up the THICK filaments, and actin makes up the thin filaments of myofibrils.
