Dietary fats, specifically cholesterol, have been given a bad image in the popular media; however, they are essential for energy
Maslowich

Dietary fats are necessary for providing energy to your body and supporting cell activity. They also aid in the protection of your organs and the preservation of your body's heat. Fats aid in the absorption of certain nutrients and the production of key hormones.

<h3>What is cholesterol?</h3>

Cholesterol is a waxy, fat-like molecule found in all of your body's cells. Cholesterol is required by your body for the production of hormones, vitamin D, and chemicals that aid digestion. Your body produces all of the cholesterol that it requires.

Fatty acids provide an ideal anisotropic solution for other membrane constituents due to their existence in bilayer membranes. They give the membrane bilayer fluidity, allowing membrane-bound receptors, enzymes, and other proteins to diffuse laterally along the bilayer membrane's surface.

The GO is a stage outside of the cell cycle commonly referred to as the "resting stage" because
Liono4ka [1.6K]

Answer:

G₀ being a stage of the cell cycle that is the resting stage, where there is no cell division, the cells that would remain in the G₀ stage throughout life are the neurons (option c).

Explanation:

In the G₀ phase, considered outside the cell cycle, there is cell metabolic activity but no cell division, since cyclins and cyclin-dependent kinases disappear. Some cells, such as neurons, do not undergo cell division throughout the life of an organism, so they remain in G₀.

In some organs, such as the liver, the hepatocyte may remain in G₀ until the organ receives an injury, and may regenerate by cell division. This is not the case of neurons, which maintain a constant quantity throughout life.

The other options are not correct because:

<em>     a. </em><em><u>Cancer cells</u></em><em> are characterized by a very active and uncontrolled cell division process.</em>

<em>     b. </em><em><u>Liver cells</u></em><em> can remain in G₀, but cell division can be activated when required.</em>

<em>     d. </em><em><u>Epithelial cells</u></em><em> are constantly dividing, since it is a tissue that undergoes frequent cell replacement.</em>
