Question

monosaccharides (1/4)
ribose
glucose
fructose
amylose
deoxyribose
disaccharides (2/4)
lactose
maltose
galactose
sucrose

Explanation:

To solve this, we need to correctly classify monosaccharides (single sugar units) and disaccharides (two sugar units):

Monosaccharides (1/4)

Monosaccharides are single sugar molecules. From the list:

• ribose: Monosaccharide (part of RNA).
• glucose: Monosaccharide (main energy source).
• fructose: Monosaccharide (fruit sugar).
• deoxyribose: Monosaccharide (part of DNA).

Amylose is a polysaccharide (starch), so it does not belong here.

Disaccharides (2/4)

Disaccharides are formed from two monosaccharides. From the list:

• lactose: Disaccharide (glucose + galactose, in milk).
• maltose: Disaccharide (glucose + glucose, from starch breakdown).
• sucrose: Disaccharide (glucose + fructose, table sugar).

Galactose is a monosaccharide, so it does not belong here.

Final Classification:

• Monosaccharides (1/4): ribose, glucose, fructose, deoxyribose (remove amylose).
• Disaccharides (2/4): lactose, maltose, sucrose (remove galactose).

If the task was to identify misclassified items:

• In monosaccharides: amylose (polysaccharide) is incorrect.
• In disaccharides: galactose (monosaccharide) is incorrect.
