Question

Who coined the term mitochondria?
A) Altman
B) Benda
C) deDuce
D) C.Golgi

Answer 1

Mitochondria are membrane-bound cell organelles that generate most of the chemical energy needed to power the cell's biochemical reactions.

Complete answer:

1. Sidney Altman, (born May 7, 1939, Montreal, Canada) is a Canadian American molecular biologist who, with Thomas R. Cech, received the 1989 Nobel Prize for Chemistry for their discoveries concerning the catalytic properties of RNA, or ribonucleic acid.
   2)Carl Benda was one of the first microbiologists to study the internal structure of cells. In an 1898 experiment using crystal violet as a specific stain, Benda was the discoverer of the existence of hundreds of these tiny bodies in the cytoplasm of eukaryotic cells and assumed that they reinforced the cell structure. Due to their tendency to form long chains, he coined the name mitochondria to those structures.
2. Christian Viscount de Duve was a Belgian cytologist and biochemist. He made the discoveries of two cell organelles, peroxisome and lysosome, for which he shared the Nobel Prize in Physiology or Medicine in 1974 with Albert Claude and George E. Palade.
3. Camillo Golgi was an Italian biologist and pathologist known for his works on the central nervous system. He was the discoverer of the Golgi bodies in the cytoplasm of cells.

Additional information: Chemical energy produced by the mitochondria is stored in a small molecule called adenosine triphosphate (ATP). Mitochondria contain their own chromosomes. Usually, mitochondrial DNA is inherited only from the mother organelle.

Thus, the correct answer is option B (Benda).

Note: Mitochondria are membrane-bound organelles, but they're membrane-bound with two different membranes.Mitochondria are called “powerhouse” of the cells.
