Is fermentation an exothermic or endothermic process?

Answer 1

It is exothermic reaction. Why should bacteria go and spend energy to ferment any thing should a question, come to your mind.

I view the situation in terms of the energy levels. In a typical glucose fermentation, you start with high energy glucose. The final product after, for example human digestion is considered, is low energy carbon dioxide and water. Some way down the slippery slope you have alcohol, i.e. energy has been lost = exotherm.

To give an example, a typical beer fermentation can increase in temperature at the rate of 0.6'C per hour, but this depends on the fermentation temperature, the yeast and the amount of glucose present. Without cooling, the temperature of the fermentation increases such that the character of the final prodcut is adversely affected.

Answer 2

it is exothermic because energy is released

Answer 3

Answer: Undecided.

Most fermentations are exothermic, though endothermics are also possible.

Answer 4

Fermentation is an exothermic process, meaning that it releases heat as a byproduct. This heat is generated as a result of the biochemical reactions that occur during the fermentation process.
