Question
Chapter 9.2, Problem 2CS
Summary Introduction
To determine: The specific model for predicting the location of amino acid substitution for the prevention of the activation of receptors. The model that has to be labeled such that two Xs are at the place where glutamic acid can be found in the mutant receptor, and one Y should be at the place where no glutamic acid is found.
Introduction: The binding of the ligand with the enzyme-linked receptors is very important for the normal functioning of the cell. The binding of cells results in the activation of the enzyme-linked receptors.

Sequence of muscle contraction
Number the following statements in their proper sequence to describe the contraction mechanism in a skeletal muscle cell.
_____ A. Acetylcholine is released into the neuromuscular junction by the axonal terminal.
_____ B. The action potential, carried deep into the cell, causes the sarcoplasmic reticulum to release calcium ions.
____ C. The muscle cell relaxes and lengthens.
_____ D. Acetylcholine diffuses across the neuromuscular junction and binds to receptors on the sarcolemma.
____ E. The calcium ion concentration at the myofilaments increases; the myofilaments slide past one another, and the cell shortens.
_____ F. Depolarization occurs, and the action potential is generated.
_____ G. As calcium is actively reabsorbed into the sarcoplasmic reticulum, its concentration at the myofilaments decreases.
