Final answer:
Cellular respiration involves redox reactions and converts glucose into ATP, CO2, and H2O. The process includes glycolysis, the Krebs cycle, and oxidative phosphorylation, primarily occurring in the mitochondria.
Step-by-step explanation:
The correct answer that describes cellular respiration is that oxidation and reduction (redox) reactions are involved in cellular respiration. Cellular respiration is the process by which cells convert nutrients, particularly glucose, into energy (in the form of ATP) and release waste products such as CO2 and H2O.
This process involves many chemical reactions, of which many are redox reactions, occurring in three main stages: glycolysis, the Krebs cycle (also known as the citric acid cycle), and oxidative phosphorylation. Glycolysis takes place in the cytoplasm and is anaerobic, whereas the Krebs cycle and electron transport require oxygen and occur in the mitochondria. The overall reaction for cellular respiration can be summarized by the chemical equation: C6H12O6 + 6O2 → 6CO2 + 6H2O + Chemical Energy (in ATP).
