What else can I help you with?
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.
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 membranous network that surrounds each myofibril?
The membranous network that surrounds each myofibril is known as the sarcoplasmic reticulum (SR). It plays a crucial role in muscle contraction by storing and releasing calcium ions, which are essential for initiating the contraction process. The SR is a specialized form of endoplasmic reticulum found in muscle cells, and it helps regulate calcium levels in the cytoplasm during muscle activity.
What separates one sarcomere from the next?
Z-lines separate one sarcomere from the next within a myofibril. These are structures composed of actin filaments where thin filaments from adjacent sarcomeres are anchored.
Is Eris made up of gas or rock?
it is mostly made up of rock
What makes up a myofibril?
Myofibrils are made up of actin (thin filaments) and myosin (thick filaments).
