Answer:
B. False
Explanation:
Yeast cells prefer to use monosaccharides, such as glucose and fructose, as substrates for fermentation because they can be readily taken up and metabolized without additional steps. Disaccharides, like sucrose and lactose, need to be broken down into monosaccharides before yeast cells can use them for fermentation. Therefore, fermentation by yeast cells favors monosaccharides over disaccharides as substrates.
