What is one of the functional units of a myrofibril?

One of the functional units of a myofibril is the sarcomere. The word sarcomere comes from the Greek words sarx, meaning flesh, and meros, meaning part.


What are tiny contractile units linked together on a myofibril?

Sarcomeres are the tiny contractile units linked together on a myofibril. They are the functional units of muscle tissue and are responsible for muscle contractions. Sarcomeres consist of thick and thin filaments made of proteins that slide past each other during muscle contraction.


What is the basic functional unit of a myofibril?

sarcomere


What are Myofibrils composed primarily of?

Myofibrils are primarily composed of proteins called actin and myosin. These proteins are arranged in a repeating pattern along the length of the myofibril, forming the sarcomeres, which are the functional units responsible for muscle contraction.

The smallest functional unit of the muscle fiber?

The smallest functional unit of a muscle fiber is the sarcomere. Sarcomeres are composed of actin and myosin filaments arranged in a repeating pattern, allowing for muscle contraction and relaxation to occur. They are responsible for the striated appearance of skeletal muscle under a microscope.

Long filamentous organelle with a banded appearance?

This description matches a structure called a myofibril, which is found in muscle cells. Myofibrils are made up of repeating units called sarcomeres that give them a banded appearance. They are responsible for muscle contractions by interacting with motor proteins.
