Just like we need energy to get through the day, individual cells need energy for survival too. Cellular respiration is the process by which cells get their energy in the form of ATP.There are two types of cellular respiration, aerobic and anaerobic.Aerobic respiration is more efficient and can be utilized in the presence of oxygen, while anaerobic respiration does not require oxygen.ellular respiration is the process by which cells get their energy in the form of ATP.

Mitochondria. Mitochondria are rod-shaped organelles that can be considered the power generators of the cell, converting oxygen and nutrients into adenosine triphosphate (ATP). ATP is the chemical energy currency of the cell that powers the cell's metabolic activities. This process is called aerobic respiration and is the reason animals breathe oxygen.
