Why is this temperature used?30°C, any hotter would denature the enzymes in the yeast, any cooler would slow the reaction down10°C, to prevent the enzymes in the yeast from denaturing300°C, to ensure a high rate of reaction0°C, to prolong the life of the yeastQuestion 8 of 14 Loading... 9.

In the production of ethanol by fermentation, why is the process done at an optimal temperature of 30⁰C?To increase the life span of the yeast, so the production doesn\'t have to be stopped often to replace themSo 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 prevent the reaction happening too quickly, leading to a dangerous build up of ethanolQuestion 14 of 14 Loading...
