Question
Chapter 10, Problem 12DYKB
Summary Introduction
To draw:
A sarcomere including thick filament, thin filament, A band, H zone, I band, Z disc, and M line.
Concept introduction:
Muscle is formed by the skeletal muscle fiber and they contain cytoplasm with cellular structures such as ribosomes, Golgi apparatus and vesicles. Myofilaments are arranged in repeating units called sarcomeres.

Explain. At the EM level, focusing on one sarcomere, you would be able to see a region of thick filaments overlapping two regions of thin filaments. Use the structure of the thick filaments to explain how ONE region of thick filaments is able to pull in microfilament in two opposite directions (both toward the center of the sarcomere).arrow_forward
