Answer:
B. Mitochondria
Read Explanation:
The majority of archaea, eukaryotes, and bacteria break down glucose using a process known as glycolysis.
It is in charge of generating compounds that serve as precursors for the metabolic processes carried out inside cells as well as energy and reduced electron carriers.
Pyruvate can go through either aerobic or anaerobic respiration after glycolysis to go through additional breakdown and release more energy.
The breakdown of pyruvate using O₂ takes place in the mitochondria matrix.
When glucose gets converted to pyruvate by glycolysis, only a small fraction of the total free energy potentially available from the glucose is released.
In mitochondria, when the metabolism of sugars is completed: the pyruvate is imported into the mitochondria and oxidized by O₂ to CO2 and H2O.
When oxygen is present, pyruvate enters the Krebs cycle in the mitochondria where it is broken down anaerobically.
This allows 15 times more ATP to be made as compared to that produced by glycolysis alone.
