When myosin is attached to actin this is called a?
Cross bridge
What specifically is cross bridge?
myosin binding to actin
Difference between actin and myosin?
Myosin is a molecular motor that converts ATP to energy. Actin is responsible for cell movement and uses energy from the ATP conversion done by myosin..
What are the proteins are involved in muscle contraction?
Actin and myosin
What is a temporary connection between actin and myosin heads?
Cross bridge
What is the crossbridge cycle?
The crossbridge cycle is the cyclical formation of links between actin and myosin. This results in the sliding of thin filaments towards the M line of a sarcomere. The myosin head undergoes conformation changes which allows it to swivel back and forth. In its low energy form, myosin has a low affinity for actin. The ATP prepares myosin for binding with actin by moving it to its high energy form position. When myosin contracts, it has a high affinity for actin.
Which proteins found myofilaments contains the cross bridge?
The two muscle filaments are Myosin and Actin. Myosin is the thicker of the two. When a muscle contracts, a hook like particle extends off the myosin and grabs the actin pulling it in causing the contraction/ tension of the muscle
What are the names of protein filaments in a muscle fiber?
Actin Filaments
An energy molecule that facilitates the sliding motion of actin and myosin?
ATP
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 the cross-bridge cycling requires?
What cross-bridge cycling requires is ATP, actin, inorganic phosphate, myosin, and ADP.
