Sucrose and lactose are disaccharides that have the same chemical formula, C12H22O11. However, these sugars have different chara
cteristics and behave differently in chemical reactions. Which of the following generalizations can explain this? Disaccharides are used for different cellular processes, and they only take part in reactions in which they are needed.
Disaccharides are different in structure because they are not made up of the same monosaccharides, and this gives them different properties.
Disaccharides are made from the same monosaccharides, but the monosaccharides are arra
The answer is <span>Disaccharides are different in structure because they are not made up of the same monosaccharides, and this gives them different properties.
Both sucrose and lactose are disaccharides, however, they are made up different monosaccharides: Disaccharide = monosaccharide + monosaccharide Sucrose = glucose + fructose Lactose = glucose + </span>galactose
Since they have different structures, their characteristics and behaviour in chemical reactions must differ, too.
In the presence of lactose, and in the absence of glucose, lactose will bind to a protein called a "repressor," deactivating it. Through this, RNA polymerase has a free way to synthesize the mRNA that will give enzymes for lactose degradation.
