The Latin verb supponere, meaning substitute, has several legitimate heirs in English, including supposititious (which dates from the early 17th century) and supposition (a 15th century addition).
Cellular respiration takes place in the organelles called mitochondria. The mitochondria take in glucose, a type of sugar, and change it in the presence of oxygen into an energy-rich molecule called ATP, or adenosine triphosphate. For every molecule of glucose, 36 molecules of ATP are made.
~ Fermentation and cellular respiration differ in that fermentation does not require oxygen while cellular respiration does. Fermentation and cellular respiration are also different because water molecules are not produced during fermentation but are produced during cellular respiration.All fermentation reactions occur in the cell's cytoplasm but during cellular respiration, only glycolysis occurs in the cytoplasm. Fermentation and cellular respiration are alike in that they both begin with a series of reactions known as glycolysis, which breaks glucose molecules into smaller pyruvate molecules. They are also similar in that during both processes, ATP is produced for the cell to use.
