Question

Do prokaryotes have mitochondria?

Answer 1

Hint: A prokaryotic cell is one that lacks a true nucleus as well as membrane-bound organelles. The prokaryotic cell is used for species in the realms Bacteria and Archaea, while all other forms of life are eukaryotic. Prokaryotic cells, on the other hand, are prolific and account for a large portion of the Earth's biomass.

Complete answer:
No prokaryotes does not contain mitochondria. Since prokaryotes lack mitochondria for energy production, they must rely on their immediate surroundings for energy. Prokaryotes get a lot of their energy from electron transport chains in their plasma membranes. The energy donors and acceptors for these electron transport chains are very diverse, representing the wide variety of environments where prokaryotic live. First and foremost, the essential organic compounds that make up prokaryotes' biomolecules are present as macronutrients such as carbon, oxygen, hydrogen, nitrogen, sulphur, and so on.

Because of their small size, prokaryotes need only small quantities of nutrients, which they acquire through processes such as electron transport chains. They just need a source of energy ,carbon and nutrients to survive. They generate energy in the same way as mitochondria do, by using the oxidation machinery found in their cell membrane (which is similar to the structure of the membrane of the mitochondria).

Electrons are converted to oxygen in aerobic prokaryotes, just as they are in mitochondria.Prokaryotes' scale is limited by the difficulties associated with energy production. When the number of these cells becomes greater, so do their energy requirements.However, as they grow in size, their surface area — and thus their ability to absorb nutrients and transport electrons — does not grow in lockstep with their volume. As a result, prokaryotic cells are typically small in order to efficiently maintain the energy supply and demand balance.

Note: According to one hypothesis about eukaryotic evolution, mitochondria were the first prokaryotic cells that lived inside other cells. Over time, evolution merged these different species into a eukaryote, which behaves as a single organism.
