Question

which gas is produced as a result of fermentation?
multiple choice
oxygen
hydrogen
nitrogen
carbon dioxide

Explanation:

Fermentation is an anaerobic process. In alcoholic fermentation (a type of fermentation), glucose is broken down. The chemical equation for alcoholic fermentation is \(C_6H_{12}O_6
ightarrow2C_2H_5OH + 2CO_2\). Carbon - dioxide (\(CO_2\)) is a by - product of fermentation. Oxygen is not produced as it is not involved in the anaerobic breakdown of glucose in fermentation. Hydrogen and nitrogen are not typical products of the common fermentation processes (like alcoholic fermentation in yeast which is a well - known example).

Answer:

carbon dioxide
