Cellular respiration is essentially:
Correct answer: A. Oxidation process
- A. Oxidation process
- B. Redox process
- C. Reduction process
- D. Decarboxylation process
Explanation
The correct answer is Option A) Oxidation process. Cellular respiration is fundamentally an oxidation process, where organic molecules are broken down to produce ATP, primarily through the loss of electrons. Option B is partially correct because cellular respiration is a redox process, but the primary focus here is on oxidation. Option C is incorrect because the process is not solely about reduction; rather, it includes reduction as part of the redox reaction. Option D is incorrect, as decarboxylation is just one aspect of cellular respiration and does not define the entire process.

About Bioenergetics
Cellular respiration explains how cells release energy from glucose through glycolysis, the link reaction, Krebs cycle and electron transport chain. It includes ATP production, substrate-level and oxidative phosphorylation, aerobic versus anaerobic respiration, and the roles of mitochondria, oxygen and fermentation in energy transfer.
