Answer:
See the answer and explanation below, please.
Explanation:
The plasma membrane is composed of:
- Lipid bilayer (highlights: phosphoglycerides such as phosphatidylethanolamine or cephalin, phosphatidylcholine or lecithin, phosphatidylinositol and phosphatidylserine; sphingolipids formed by ceramide and fatty acids, and cholesterol)
- Proteins: integral, peripheral and membrane fixed to lipids.
- Glucids: covalently bound to proteins or lipids; they can be poly or oligosaccharides. They form the glycocalix on the outside of the membrane and its function is to support the membrane and cell recognition.

The mitochondrial dysfunction has emerged as one of the key hallmarks aging process and is linked to the development of numerous age-related pathologies including metabolic syndrome, neurodegenerative disorders, cardiovascular diseases and cancer.
<h3>Mitochondrial dysfunction </h3>
Chronic (long-term), hereditary, and frequently inherited ailments known as mitochondrial illnesses take place when mitochondria are unable to create enough energy for the body to function normally. When a condition is inherited, it indicates that parents have passed it on to their offspring. In addition to developing at any age, mitochondrial illnesses can be present at birth.
Affected organs by mitochondrial illnesses include the brain, nerves, muscles, kidneys, heart, liver, eyes, ears, and pancreas. They can also affect the cells of the kidneys. When the mitochondria don't perform as well as they should as a result of another illness or condition, mitochondrial dysfunction arises.
