I'm not sure whether there's another process , but there are two types of respiration the first one is a aerobic respiration , which is when the reaction or the chemical reaction in cells uses oxygen to break down nutrient molecules to release energy .Another type which is anaerobic respiration which means the opposite of aerobic respiration it is the term for the chemical reaction in cells that break down nutrient molecules to release energy with out using oxygen for example fermentation in yeast .
