Answer:

Chain-link fence

Explanation:

Cell membranes are barriers that decide which molecules enter and exit the cell, and how much of them come in. So things are able to pass through them.

If it were a brick wall, it would not let anything pass through.

So it is more like a chain-link fence, but with more control over what passes through it.

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.
