In a person with a disease in which the mitochondria do not produce enough energy for the cell, which organs would be the most s
erastova [34]

The heart would be one of the most affected organs if the mitochondria do not produce enough energy, since this organ requires a lot of energy, so any supply failure leads to heart failure and contraction failure.

<h3>What are mitochondria?</h3>

They are the cellular structures responsible for supplying most of the energy necessary for cellular activity.

<h3>Characteristics of mitochondria</h3>

  • They produce energy from the metabolism of organic fuels such as sugars, lipids (fatty acids) and amino acids.

  • Insufficient energy production by the mitochondria causes dilated cardiomyopathy, where the heart undergoes significant dilation and loses the force of contraction.

Therefore, we can conclude that a defect in a mitochondrial process involved in energy production would affect heart cells causing dilated cardiomyopathy, heart failure.
