Muscles
Actin is the protein that forms the contractile thin filaments of muscle cells in the human body. It plays a key role in muscle contraction by interacting with myosin to generate the force required for muscle movement.
That's correct, marine protozoa do not have contractile vacuoles. Contractile vacuoles are typically found in freshwater protozoa and serve to regulate water balance by expelling excess water from the cell. Marine protozoa have adaptations to maintain water balance in a high-salt environment without the need for contractile vacuoles.
They are found in aquatic protists.They remove excess water.
A specific type of vacuole, called a contractile vacuole expels excess water from many fresh water protists.
Myosin protein is primarily found in muscle cells, where it is a key component of the thick filaments that form part of the contractile machinery responsible for muscle movement. Myosin interacts with actin, another protein, to create the sliding motion that leads to muscle contraction.

Actin and Myosin
Contractile proteins are found in what?
False.... protein actin
The heavy chain contractile element within the sarcomere is myosin. Myosin is a motor protein that interacts with actin to generate the force and movement in muscle contraction.
No. It results in mitochondrial adaptations
Troponin is a regulatory protein while tropomyosin is a contractile protein. Troponin is involved in regulating muscle contraction by controlling the interaction between actin and myosin. Tropomyosin works in conjunction with troponin to regulate the binding of myosin to actin during muscle contraction.
Contractile vacuoles are primarily found in single-celled organisms, such as protists, that live in freshwater environments. They help regulate the water content of the cell by pumping out excess water to prevent it from bursting. Neither animal nor plant cells typically possess contractile vacuoles.
Contractile vacuole is found in paramecia cells but not plant cells. It helps in expelling excess water from the cell to maintain osmotic balance.
