# Write the equations to show how lactic fermentation compares with alcoholic fermentation. Which reactant(s) do they have in common?

a) Lactic fermentation: $C_{6} H_{12} O_{6} \rightarrow 2 C_{3} H_{6} O_{3}$ (glucose $\leftarrow$ lactic acid)
Alcoholic fermentation: $C_{6} H_{12} O_{6} \rightarrow 2 C_{2} H_{5} O H+2 C O_{2}$ (glucose $\leftarrow$ ethanol + carbon dioxide)
Both types of fermentation share glucose as a common reactant.
b) Lactic fermentation: $C O_{2}+H_{2} O \rightarrow C_{3} H_{6} O_{3}$ (carbon dioxide + water $\leftarrow$ lactic acid)
Alcoholic fermentation: $C O_{2}+H_{2} O \rightarrow C_{2} H_{5} O H$ (carbon dioxide + water $\leftarrow$ ethanol)
They both have carbon dioxide and water in common as reactants.
c) Lactic fermentation: $C_{6} H_{12} O_{6} \rightarrow C_{2} H_{5} O H$ (glucose $\leftarrow$ ethanol)
Alcoholic fermentation: $C_{6} H_{12} O_{6} \rightarrow C_{3} H_{6} O_{3}$ (glucose $\leftarrow$ lactic acid)
They have glucose and ethanol in common as reactants.
d) Lactic fermentation: $C_{6} H_{12} O_{6}+O_{2} \rightarrow C_{3} H_{6} O_{3}$ (glucose + oxygen $\leftarrow$ lactic acid)
Alcoholic fermentation: $C_{6} H_{12} O_{6}+O_{2} \rightarrow C_{2} H_{5} O H+C O_{2}$ (glucose + oxygen $\leftarrow$ ethanol + carbon dioxide)
They both share oxygen as a common reactant.
