Answer:

Mitochondria are rod-shaped organelles that can be considered the power generators of the cell, converting oxygen and nutrients into adenosine triphosphate (ATP). ATP is the chemical energy "currency" of the cell that powers the cell's metabolic activities. This process is called aerobic respiration and is the reason animals breathe oxygen. Without mitochondria (singular, mitochondrion), higher animals would likely not exist because their cells would only be able to obtain energy from anaerobic respiration (in the absence of oxygen), a process much less efficient than aerobic respiration. In fact, mitochondria enable cells to produce 15 times more ATP than they could otherwise, and complex animals, like humans, need large amounts of energy in order to survive.

Hi FRIEND-

Mitochondria are critical to cell survival in a variety of ways. For instance, they store calcium ions, helping cells maintain the right concentration of these electrically charged particles involved in blood clotting, muscle contraction and other important tasks.Mitochondria are membrane-bound cell organelles (mitochondrion, singular) that generate most of the chemical energy needed to power the cell's biochemical reactions. Chemical energy produced by the mitochondria is stored in a small molecule called adenosine triphosphate (ATP).When the mitochondria are damaged, lactate levels rise in the bloodstream and lead to lactic acidosis. ... As the severity increases and lactate levels rise over 5 mmol/liter (the normal value is less than 2), mitochondria lose their ability to produce energy, leading to potentially irreversible organ damage and death.Mitochondria are shaped perfectly to maximize their productivity. They are made of two membranes. The outer membrane covers the organelle and contains it like a skin. The inner membrane folds over many times and creates layered structures called cristae.Mitochondria are shaped perfectly to maximize their productivity. They are made of two membranes.

Because mitochondrial DNA has a limited ability to repair itself when it is damaged, these mutations tend to build up over time.
