What are the hazardous by-products of lactic acid and alcohol fermentation?

Options

ACO2 and water
BAcid or alcohol
COxygen and nitrogen
DHydrogen and methane

Correct answer

B. Acid or alcohol

Step-by-step solution

In both lactic acid and alcohol fermentation not much energy is released; less than seven per cent of the energy in glucose is released and not all of it is trapped as high energy bonds of ATP. Also, the processes are hazardous – either acid or alcohol is produced. Yeasts poison themselves to death when the concentration of alcohol reaches about 13 per cent
