To differentiate acid production by glucose and lactose fermentation in a test tube one must look at the neck and the butt of the test tube. Different colors indicate fermentation or non-fermentation.
Cellular respiration produces water but fermentation does not.Respiration: glucose + oxygen --> carbon dioxide + water Fermentation: glucose --> alcohol + carbon dioxide
fermentation
Hi
During glucose breakdown, glycolysis and fermentation occur anaerobically. Glycolysis breaks a glucose molecule into energy and pyruvate. Fermentation uses to the pyruvate to form either ethanol or lactate.
Substrate for fermentation is usually glucose. But depending on the yeast type it can be fructose or other monossaccharides too.
-1277.36kJ is the heat of combustion of ethanol. It is not the heat of fermentation for the production of ethanol.
ATP production begins with glucose..
Alcohol Fermentation Glucose --> ATP+CO2+Alcohol Lactic Acid Fermentation Glucose --> ATP+Lactic Acid
The higher concentartion of glucose means a slower rate of reaction for fermentation.

Glucose and water

There are two types of fermentation, alcoholic and lactic acid fermentation. The reactant for both is glucose, C6H12O6.
