Why don't all the disaccharides undergo fermentation with yeast?
Understand the Problem
The question is asking why not all disaccharides can be fermented by yeast, which involves understanding the types of disaccharides and the ability of yeast to utilize them during fermentation. This involves concepts from biochemistry and microbiology.
Answer
Yeast lacks enzymes to break down certain disaccharides.
Not all disaccharides undergo fermentation with yeast because yeast lacks the necessary enzymes to break down certain types of disaccharides into fermentable sugars.
Answer for screen readers
Not all disaccharides undergo fermentation with yeast because yeast lacks the necessary enzymes to break down certain types of disaccharides into fermentable sugars.
More Information
Yeast can ferment sugars like glucose, fructose, and maltose effectively, but it cannot ferment disaccharides like lactose due to the lack of necessary enzymes such as lactase.
Tips
A common mistake is to assume that all sugars interact similarly with yeast, but enzyme specificity significantly affects this process.
