Explanation:

Step1: Identify Alcoholic Fermentation Equation

Alcoholic fermentation (like in yeast for beer) uses glucose (\(C_6H_{12}O_6\)) and produces ethanol (\(C_2H_6O\)) and carbon dioxide (\(CO_2\)), with yeast as a catalyst. The equation is \(C_6H_{12}O_6 \xrightarrow{\text{yeast}} 2C_2H_6O + 2CO_2 + 2\text{ATP}\).

Step2: Identify Lactic Acid Fermentation Equation

Lactic acid fermentation (in muscle cells) uses glucose (\(C_6H_{12}O_6\)) and produces lactic acid (\(C_3H_6O_3\)) and ATP. The equation is \(C_6H_{12}O_6
ightarrow 2C_3H_6O_3 + 2\text{ATP}\).

Answer:

Alcoholic Fermentation (Top Section):

• Equation: \( \boldsymbol{C_6H_{12}O_6} \xrightarrow{\text{yeast}} \boldsymbol{2C_2H_6O + 2CO_2} + 2\text{ATP} \)
• Labels: Top box (process): Alcoholic Fermentation; Middle box (reactant): \(C_6H_{12}O_6\); Products: \(2C_2H_6O\) (ethanol) and \(2CO_2\) (carbon dioxide).

Lactic Acid Fermentation (Bottom Section):

• Equation: \( \boldsymbol{C_6H_{12}O_6}

ightarrow \boldsymbol{2C_3H_6O_3} + 2\text{ATP} \)

• Labels: Top box (process): Lactic Acid Fermentation; Reactant: \(C_6H_{12}O_6\); Product: \(2C_3H_6O_3\) (lactic acid).
