Aerobic cellular respiration

It is a process that uses oxygen to yield energy from glucose by using mitochondria present in the cells.

Equation for cellular respiration

C6H12O6 + 6O2 -> 6CO2 + 6H2O+36 ATP+ Heat

Reactants: C6H12O6 + 6O2

Products: 6CO2 + 6H2O

4 stages of cellular respiration

1.Glycolysis2.Pyruvate oxidation3.Kreb’s cycle4.Electron transport and

chemiosmosis

Structure of Mitochondria

Anaerobic respirationCellular respiration in absence of oxygen is known as anaerobic respiration. It can happen in animals and yeast cells.

Aerobic Anaerobic 1. Takes place in presence of oxygen

1. Takes place in absence of oxygen

2. Produce 36 ATP 2. Produce 2 ATP

3. Reactants are glucose and oxygen

3. Reactant is glucose

4. Location is cytoplasm and mitochondria

4. Location is only cytoplasm
