Document Summary
Robert altmann discovered mitochondria in 1886, thinking that he was seeing parasites. Altmann called his discovery bioblasts and posited that they were found in almost all cells. His ideas laid the foundation for additional discoveries by scientists. These scientists believe mitochondria originated from prokaryote cells that were incorporated into ancient eukaryote cells. There are typically multiple mitochondria found in a singular cell, depending upon the function of that particular type of cell. Exceedingly active cells, such as muscle cells, have hundreds of mitochondria; insufficiently active cells, such as fat storage cells, have few of these organelles. Mitochondria are located in the cytoplasm of cells along with other organelles of the cell. Mitochondria transfer energy from organic materials to adenosine triphosphate (atp). Chemical reactions are mostly powered by the atp. A mitochondrion supports an inner and outer phospholipid membrane. The outer separates mitochondria and cytosol, whereas the inner just contains many folds called cristae.
