Reaction that does not require oxygen

The reaction is called Anaerobic respiration.

Explanation:

The reaction that doesn't require oxygen is known as Anaerobic reaction. Anaerobic respiration is the ability of an organism to produce energy in the form of Adenosine Triphosphate (ATP) without using oxygen. Instead, sulfate, nitrate or sulfur is used. To break down the equation above, organisms that use anaerobic respiration to produce energy start with glucose. Glucose is sugar, and the same sugar from the photosynthesis equation 6CO2 + 6H20 = C6h1206 + 6 02. Organisms take glucose, and through the electron transport chain, produce ethanol or lactic acid, CO2, and ATP.

its temperature is increasing. this causes molecular vibrations to increase.
