Answer;
-In the smooth ER
In certain kinds of muscle cells, calcium ions are stored in the smooth ER.
Explanation;
-The smooth endoplasmic reticulum is the part of the endoplasmic reticulum (ER) which does not have ribosomes bound to it, thus not exhibiting the bumpy appearance shown by the rough endoplasmic reticulum.
-The smooth ER is important in the synthesis of lipids, such as cholesterol and phospholipids, which form all the membranes of the organism. In addition it is important for the synthesis and secretion of steroid hormones from cholesterol and other lipid precursors.

The answer choice above which best describes how the cell cycle relates to neurons is:
Neurons do not go through M phase.
Option a is the correct answer
<h3>What is a neuron?</h3>
A neuron is defined as structural and functional unit of the nervous system
Complete question:
In humans, adult brain cells called neurons are terminally differentiated. This means that they are completely mature and no longer undergo the cell cycle.
Which of the following statements best describes how the cell cycle relates to neurons?
a. Neurons do not go through M phase.
b. Neurons passes through the M phase
c. None of the above
So therefore, the answer choice above which best describes how the cell cycle relates to neurons is:
Neurons do not go through M phase.
