What triggers the binding of myosin to actin?
Calcium ions bind to troponin and change its shape.
What are the proteins are involved in muscle contraction?
Actin and myosin
What substance triggers muscle contractions?
Ca++ ions initiate the movements but actin and myosin hormones regulates it.
What are the names of protein filaments in a muscle fiber?
Actin Filaments
How do proteins actin and myosin interact to make a muscle contract?
Myosin and Actin
What is the name of the regulatory protein?
myosin and actin
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.
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 protein makes up the thick filaments of myofibrils?
Myosin makes up the THICK filaments, and actin makes up the thin filaments of myofibrils.
Does protein make actin and myosin?
Actin and myosin are proteins. Protein is a broad category of molecules.
What other protein is involved in skeletal muscle contraction?
Myosin and actin
What is actin or myosin-containing structure?
actin and myosin are myofillaments that make up myofibrils (part of a muscle fibre) (so therefore : muscle is an actin or myosin containing structure
