by the process of respiration
Fermentation
In the absence of oxygen in the absence of oxygen
They use energy from carbon -di-oxide & it is known as anaerobic respiration.It occurs in the absence of oxygen & release 2 molecules of ATP from one glucose molecule. It also produces alcohol & lactic acid
Cellular respiration is the process by which cells produce energy (in the form of ATP) from food (glucose) in the presence of oxygen.
Fermentation!!!!!
Cellular respiration
The release of energy from food molecules in the absence of oxygen is called anaerobic respiration. When there is oxygen present it is called aerobic respiration.
In the absence of oxygen in the absence of oxygen
Glycolysis and Fermentation both produce ATP in the absence of oxygen. These are both part of Anaerobic Respiration.
In the absence of oxygen, however, an anaerobic process can produce small amounts of ATP to keep the cell from dying.
A cell releases energy from food in the process of cellular respiration which is in the presence of oxygen, or fermentation which is in the absence of oxygen.
