How do mitochondria differ from ribosomes?
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).
