Question
Chapter 11.4, Problem 14BYGO
Summary Introduction
To analyze:
The role of troponin and tropomyosin in regulating the interaction between myosin and actin.
Introduction:
Excitation− Contraction coupling is the second phase of the process of muscle contraction and relaxation. This phase incorporates the events that bring about a connection between the action potentials formed on sarcolemma and the activation of myofilaments leading to contraction.

How do troponin and tropomyosin regulate the interactionbetween myosin and actin?
What are the mechanisms for muscle contraction vs. relaxation in regards to myosin/thick filaments/thin filament movement? Is it true that if tropomysin blocks myosin sites, contraction ends and muscle relaxes?
What prevents the filaments from sliding back to their original position each time a myosin cross bridge detaches from actin?
