How do mitochondria differ from ribosomes?

Question

Daniel Arnold · Accepted Answer

Both are organelles in the cell.

Mitochondria are found in animal, plant, fungal and some bacterial cells whereas Ribosomes are found in all cells.

The mitochondria are responsible for aerobic respiration meaning they use Oxygen to 'burn' sugar (glucose is used in the cell) and generate energy in the form of ATP (Adenosine TriPhosphate).

The Ribosomes are where proteins are made. They receive messenger RNA which is the blueprint for the protein and read it and build the protein before it is sent off to be modified and used.

(an amino acid is one part of a protein, a polypeptide chain is what will become the protein. The mRNA is messenger RNA that is inserted between subunits and read off by tRNA: transfer RNA).

undefined Membrane-bound organelles called mitochondria produce energy in the form of ATP through cellular respiration; non-membrane-bound organelles called ribosomes are responsible for protein synthesis; eukaryotic cells contain mitochondria, which have their own DNA and are able to replicate independently, whereas prokaryotic cells contain ribosomes, which are made up of RNA and proteins.

Clara Atchley · Answer

undefined Mitochondria are membrane-bound organelles responsible for producing energy in the form of ATP through cellular respiration. They have their own DNA and ribosomes, allowing them to produce some of their proteins independently. Ribosomes, on the other hand, are cellular structures responsible for protein synthesis. They can be found free-floating in the cytoplasm or attached to the endoplasmic reticulum. Ribosomes consist of RNA and proteins and are not membrane-bound organelles. While both mitochondria and ribosomes are involved in protein synthesis to some extent, their primary functions and structures differ significantly.
