Step 1
Justify why Statement A in Table 2 shows aerobic energy release.
Answer
Statement A illustrates aerobic energy release because it involves the presence of oxygen in the equation. In aerobic respiration, oxygen is a critical component for the conversion of glucose into energy. This process produces carbon dioxide and water as by-products, indicating a complete oxidation of glucose. Conversely, Statement B lacks oxygen, which is essential for aerobic respiration, and instead shows anaerobic respiration, which produces lactic acid as a by-product. Therefore, the inclusion of oxygen in Statement A distinguishes it as aerobic respiration.
