  1. Question 1

    Q1. During the industrial fermentation of molasses to produce ethanol, the temperature is strictly maintained below 35C. What occurs if the temperature reaches 55C?

    • A) Alcohol evaporates rapidly
    • B) Enzymes become inactive
    • C) Sugar converts to acetic acid
    • D) Carbon dioxide pressure drops

    Answer: Enzymes become inactive

    Explanation: Enzymes like zymase and diastase are proteins that denature at temperatures above 35C, stopping the fermentation process of molasses effectively.
