Energy metabolism in the cell, the role of mitochondria in it.

Mitochondria are directly involved in obtaining energy. Mitochondria are membrane organelles that oxidize organic matter. This is how energy is obtained. Mitochondria can be called “power plants” or “power plants” of the cell. Also, cells store a supply of organic matter. Thanks to this, organisms do not die due to a short-term lack of organic matter. They can either receive these substances ready-made (heterotrophs) or synthesize independently (autotrophs).
