Alcohols & Carboxylic Acids quiz Loading... 1. In the production of ethanol by fermentation, why is the process done at an optimal temperature of 30⁰C?So the yeast is warm enough to perform anaerobic respiration, but below the temperature at which the zymase enzyme would denatureSo that the yeast is warm enough to catalyse the reaction between oxygen and sugar to produce ethanolTo increase the life span of the yeast, so the production doesn\'t have to be stopped often to replace themTo prevent the reaction happening too quickly, leading to a dangerous build up of ethanolQuestion 1 of 14 Loading... 2. What is the functional group of alcohols?-COOH-OH-C-C--C=C-Question 2 of 14 Loading... 3. When fermentation is used to produce ethanol, what is the temperature? Why is this temperature used?300°C, to ensure a high rate of reaction0°C, to prolong the life of the yeast10°C, to prevent the enzymes in the yeast from denaturing30°C, any hotter would denature the enzymes in the yeast, any cooler would slow the reaction downQuestion 3 of 14 Loading... 4.
