TYPES OF RESPIRATION

1. Aerobic Respiration 

• It needs the presence of O2 and occurs in the mitochondria.
• Glucose is completely broken down to CO2 and H2O.
• It releases more energy.
• it occurs in most organisms (in all higher forms of life ).

2. Anaerobic Respiration 

• Anaerobic respiration occurs in the absence of O2 in the cytoplasm.
• It results in the incomplete oxidation of glucose into LACTIC ACID (in animals ) or ETHYL ALCOHOL (in plants).
• It releases lesser energy.
• It takes place in certain bacteria, yeast,  and certain tissues of higher organisms.
