Which process is described as combining nutrient oxygen within the cell and is also known as oxidation?

• A. Aerobic metabolism
• B. Absorption
• C. Alkalosis
• D. Anemia

Answer: (A)

The process described is cellular energy production by oxidizing nutrients with oxygen inside the cell, called aerobic metabolism. In this pathway, nutrients such as glucose are oxidized through stages like glycolysis, the citric acid cycle, and the electron transport chain, with oxygen acting as the final electron acceptor to produce ATP, carbon dioxide, and water. This is the main way cells generate energy when oxygen is available. Absorption refers to taking substances into the body, alkalosis is a high blood pH condition, and anemia is a deficiency in red blood cells or hemoglobin; none of these describe the oxidation-based production of energy with oxygen.
