Fermentation of yeast with carbohydrates
Fermentation is a metabolic process that converts carbohydrates (sugars) into acids or alcohols metabolic refers to the various processes of energy production and consumption that living things perform. Yeast environmental diversity mostly leads to a vast metabolic complexity driven by carbon and the energy available in environmental habitats it is the scope of this.

The yeast’s efficiency to use sucrose was expected to be greater than lactose (figure 1) because yeast lacks the enzyme required to break the molecule bonded by b-galatoside in lactose, and starch (figure 1) because of its slow rate of fermentation due to its size and inability to enter the yeast’s cell efficiently it wasn’t however.
