19. A cell is ready to break down pyruvate

and use it for energy. The end result of the

process includes carbon dioxide, ATP, and

byproducts. Which energy producing

pathway did the cell follow?

O A. Cellular respiration

O B. Acellular respiration

O C. Krebs's pathway

O D. Fermentation

The correct option is C. The cell followed Kreb's pathway.

Explanation:

Krebs cycle can be described as a metabolic pathway for the release of energy during the process of aerobic respiration. The Kreb's cycle constitutes a series of oxidation reactions through which pyruvate is converted into carbon dioxide. About 15 moles of ATP is released as a result of Kreb's cycle. The reactions of the Kreb's cycle take place mostly in the mitochondria. The Kreb's cycle is commonly named as the Citric Acid Cycle.
