What are Cytoskeletal filaments built of?
Cytoskeletal filaments are built of protein subunits. The three main types of cytoskeletal filaments are actin filaments (microfilaments), intermediate filaments, and microtubules, each made of specific proteins such as actin, keratins, and tubulins, respectively. These filaments help maintain cell shape, support organelles, and facilitate cell movement.
What is the job of the cytoskeleton?
The cytoskeleton provides structural support to cells, helps with cell movement and shape, and is involved in cell division. It is made up of protein filaments like microtubules, actin filaments, and intermediate filaments.
What is a network of long protein strands in the cytosol that helps maintain the shape and size of a eukaryotic cell?
The network of long protein strands in the cytosol that helps maintain the shape and size of a eukaryotic cell is the cytoskeleton. It is made up of three main types of filaments: microtubules, actin filaments (microfilaments), and intermediate filaments. These filaments provide structural support, help with cell motility, and are involved in various cellular processes such as cell division and intracellular trafficking.
What is a network of protein fillaments that helps the cell maintain its shape?
The network of protein filaments that helps the cell maintain its shape is called the cytoskeleton. It is made up of three types of filaments: microfilaments (actin), intermediate filaments, and microtubules. The cytoskeleton provides structural support, helps in cell movement, and is involved in intracellular transport.
What are cytoskeleton filaments built of?
The cytoskeleton is made up of three kinds of protein filaments:Actin filaments (also called microfilaments)Intermediate filaments andMicrotubules
The thick filaments of muscle fibers are composed of what?
Myosin
What are the 3 different types of myofilaments?
The three different types of myofilaments are thick filaments, thin filaments, and elastic filaments. Thick filaments are composed of myosin protein, thin filaments are primarily made of actin protein, and elastic filaments (also known as titin) provide elasticity and stability to the sarcomere.
Is it true that thick filaments are made of a protein called actin?
false, it's made of myosin
What are the 3 types of filaments within a muscle and what protein makes up each filament?
The three types of filaments within a muscle are thin filaments, thick filaments, and elastic filaments. Thin filaments are primarily composed of the protein actin, while thick filaments are made up of myosin. Elastic filaments, which help maintain the structure and elasticity of the muscle, are primarily composed of the protein titin. These filaments work together to facilitate muscle contraction and relaxation.
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 are threadlike bundles of thick and thin filaments?
Threadlike bundles of thick and thin filaments refer to the structural components of muscle fibers, specifically the myofibrils. The thick filaments are primarily composed of the protein myosin, while the thin filaments are mainly made up of actin, along with tropomyosin and troponin. These filaments interact during muscle contraction through a process called the sliding filament theory, allowing muscles to generate force and movement.

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.
