Question

Myofibrils are __________. View Available Hint(s) Myofibrils are __________. made of a series of sarcomeres proteins that cover active sites on actin bundles of muscle cells inside a whole muscle connections between actin and myosin

Answer 1

Answer: proteins

Explanation:

The myofibril proteins are organized into filaments of varying sizes thick and thin and is called myofilaments.

Answer 2

Answer: Myofibrills are long fibril proteins.

Explanation:

Myofibrill protein is a rod like unit of muscle cells. It is made up of long fibril protein which form sacromeres that cover the active sites on action bundles inside a whole muscle connections between action and myosin. Myosin form the thick filament and have long tail and globular head that binds actin. Actin form the thin filament.
