What bridge forms between Calcium ions?
Calcium bridges form between muscle cells. The calcium ions bind to troponin-tropomyosin molecules in the grooves of actin filaments and form crossbridges.
The protein that interacts with actin to form crossbridges?
myosin
Where do myosin cross bridges attach during muscle contraction?
Myosin functions as an ATPase utilizing ATP to produce a molecular conformational change of part of the myosin and produces movement. Movement of the filaments over each other happens when the globular heads protruding from myosin filaments attach and interact with actin filaments to form crossbridges. The myosin heads tilt and drag along the actin filament a small distance (10-12 nm). The heads then release the actin filament and adopt their original conformation.
Myofibrils are composed primarily of two protein filaments called?
thick filaments and thin filaments
What two materials did Edison experiment with in order to make filaments?

Are thread-like filaments that form networks called a mycelium?
Thread-like filaments that form networks are called mycelium. These are vegetative parts of fungus that consists of a mass of branching.
Units of actin and myosin are arranged end to end in order to?
form the structural units responsible for muscle contraction, known as sarcomeres. Actin filaments provide the thin filaments, while myosin filaments provide the thick filaments. When the myosin heads interact with actin during muscle contraction, the sarcomere shortens, leading to muscle contraction.
What is the contractile ring in mitosis made up of?
The contractile ring in mitosis is made up of actin and myosin filaments. These filaments interact to produce the force necessary for the ring to contract and eventually pinch the cell into two daughter cells during cytokinesis.
What do sarcomere contain?
Sarcomeres contain thin (actin) and thick (myosin) filaments. These filaments overlap to create the striated appearance of skeletal muscle fibers. Sarcomeres also contain Z-lines, which anchor the thin filaments and help define the boundaries of the sarcomere.
What is an analogy for filaments?
Filaments are like the threads in a woven fabric, providing structure and support. Just as threads are interconnected to create a fabric, filaments in biology are interconnected to form structures like muscle fibers or nerve cells.
Structure of muscle?
the sacromere, contains two kinds of filaments.
What are most true fungi send out cellular filaments called?
The individual filaments are called hyphae, and these form a mesh that is called a mycelium.
