1. What is aerobic respiration? Answer choice 1) The process that breaks down glucose in the absence of oxygen to release energy

Answer choice 2) the process that breaks down glucose in the presence of oxygen to release energy

Explanation:Glucose is oxidised to release its energy, which is then stored in ATP molecules. Respiration is a series of chemical reactions, but this equation summarises the overall process. Aerobic respiration breaks down glucose and combines the broken down products with oxygen, making water and carbon dioxide.
