Final answer:
The accurate statement about cellular respiration is that organisms use it to obtain usable energy from food. Cellular respiration transforms the energy in glucose into ATP; although most stages occur in the mitochondria, glycolysis occurs in the cytoplasm, and involves multiple chemical reactions. The correct option is option B.
Step-by-step explanation:
The correct statement about cellular respiration is: Organisms use cellular respiration to get usable energy from food.
This is true because cellular respiration takes the energy stored in glucose and other nutrients and transfers it to adenosine triphosphate (ATP), which cells can use for work.
While most of the cellular respiration processes occur in the mitochondria, the first step, glycolysis, takes place in the cytoplasm. Moreover, cellular respiration includes multiple reactions, not just one.
The stages of cellular respiration involve glycolysis, the transformation of pyruvate into acetyl CoA (an intermediate stage), the Krebs cycle (also known as the citric acid cycle), and oxidative phosphorylation through the electron transport chain. Through these stages, the six carbon atoms from glucose are fully oxidized into carbon dioxide, and the chemical energy from the bonds in glucose is transferred to ATP.
