1. B 2. C
Explanation
## Step1The first question is about the similarities between anaerobic and aerobic respiration. Both processes start with the breakdown of glucose into pyruvate, a process known as glycolysis. However, they diverge after this point.## Step2The four options provided (A through D) propose different similarities:A. Both processes generate the same amount of ATP — This is not true. While ATP is the direct energy currency of cells, aerobic and anaerobic respiration do not generate the same amount of ATP. Aerobic respiration generates far more ATP than anaerobic respiration.B. Both processes rely on the breakdown of glucose into pyruvate — This is true. Both types of respiration begin with glycolysis.C. Both processes make ethanol — This is not true. While some types of anaerobic respiration (like fermentation in yeast) produce ethanol, this does not apply to aerobic respiration, which ends with water and carbon dioxide.D. Both processes use oxygen — This is also not true. Anaerobic respiration does not require oxygen, which is a defining feature of aerobic respiration.## Step3The second question asks about the necessary chemical for a cell to undergo aerobic respiration instead of anaerobic respiration. Oxygen is a clear necessity for aerobic respiration. The presence of glucose, water, or carbon dioxide are not decisive factors to differentiate between anaerobic and aerobic processes.
