In addition to providing structural support, actin filaments are involved in movement when they interact with the specialized protein myosin. Myosin is a motor protein that converts the chemical energy in ATP into the mechanical work of movement. The interaction between actin and myosin that produces movement: When ATP binds to themyosin and is then hydrolyzed to ADP, the "head" region of the myosin molecule binds to the actin filament on the slide. The movement of this protein causes the ctin filament to slide. This type of movement is analogous to a line of people who are passing along a long log or pole, the people are myosin molecules; the log is the is the actin.

Is actin and myosin a carbohydrate?
No, they are proteins.
What contracting proteins?
The two contracting proteins are actin and myosin.
What 2 proteins make up the mass of a muscle cell?
Actin and myosin interact in muscle cells.
What 2 molecules are part of actin?
Actin and myosin are the molecules used for muscle contraction.
What are 2 important proteins in human body?
Actin & myosin
What is the structural role of protein?
Structural proteins are fibrous proteins. The most familiar of the fibrous proteins are the keratins. This forms skin, fur, hair, nails, hooves, horns, beaks and feathers. Other structural proteins are the actin and myosin proteins of muscle tissue, tendons and ligaments.Structural proteins are proteins that build up our tissues or body. actin, myosin, clotting factors are some of the structural proteins. They give up a shape and rigidity to our cells or tissues and ultimately to our body (muscle).
What are the proteins are involved in muscle contraction?
Actin and myosin
How do proteins actin and myosin interact to make a muscle contract?
Myosin and Actin
Does protein make actin and myosin?
Actin and myosin are proteins. Protein is a broad category of molecules.
Is actin and myosin a carbohydrate?
No, they are proteins.
Are the two contractile proteins in muscles myosin and actin?
Yes the contractile proteins generate force during contraction and are actin and myosin
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.
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 contracting proteins?
The two contracting proteins are actin and myosin.
What 2 proteins make up the mass of a muscle cell?
Actin and myosin interact in muscle cells.
What protein makes up the thick filaments of myofibrils?
Myosin makes up the THICK filaments, and actin makes up the thin filaments of myofibrils.
What are the 2 contracting proteins?
The two contracting proteins are actin and myosin.
