Muscle glycogen is the primary fuel used during endurance exercise. Catabolism and anabolism are the two phases of metabolism.
DNA is an essential molecule for cell survival that cell cannot afford to lose the genetic information and cytoplasm contains many degrading enzymes.
In all living cells, DNA is essential for inheritance, coding for proteins, and providing instructions for life and its processes. DNA dictates how a human or animal develops and reproduces, and eventually dies.
There are two reasons why DNA cannot leave the nucleus. They are 1. DNA code is prone to damage and 2. DNA is a large molecule.
DNA cannot leave the nucleus because that would risk it getting damaged. DNA carries the genetic code and all of the information needed for cells and organisms to function properly.

Although the inner leaflet of the gram-negative outer membrane is composed mainly of phospholipids, the outer leaflet of the outer membrane contains lipopolysaccharides.
Phospholipids are the most abundant component of the plasma membrane. The structure of phospholipids is composed of a backbone of glycerol containing two fatty acid chains attached to two hydroxyl groups and one phosphate group attached to the third hydroxyl group.
Lipopolysaccharides, also abbreviated as LPS, are the major component of bacterial cell wall. The role of LPS is to provide structural integrity and high permeability to the bacteria. LPS is a pyrogen and can be toxic to human body.

The body system responsible for circulation of the blood, including the heart, arteries, veins and capillaries, is called the cardiovascular system
<h3>Cardiovascular system</h3>
To supply the lungs with oxygen, the circulatory system (cardiovascular system) pumps blood from the heart. Following that, the heart pumps oxygen-rich blood through arteries to the rest of the body. Poor in oxygen blood is returned to the heart by veins to restart the circulatory system. The cardiovascular system plays a crucial role in supplying your body with oxygen and nutrients as well as removing waste. Your cardiovascular system is how your cells obtain the nutrients they require to function properly. It is crucial to take care of your heart by exercising, eating a healthy diet, and maintaining under control your blood pressure and cholesterol.
