Whose work revealed the structure of the mitochondrion?
Quick Answer
The mitochondrion’s internal structure was revealed through electron microscopy pioneered by scientists including George E. Palade and later refined by many cell biologists. The organelle’s inner membrane folds, called cristae, became visible in the mid-20th century.
The Full Story
Mitochondria were first described in the 19th century, but their detailed structure became clear only with electron microscopy in the 20th century. George E. Palade helped establish the ultrastructure of cells using the electron microscope, and later research showed mitochondria have a double membrane with inner folds called cristae. These features are central to ATP production, the cell’s energy currency. The organelle is now known to play roles in metabolism, signaling, and programmed cell death.
