Question

monosaccharides are the building blocks of carbohydrates. they may be found alone or combined with other molecules in fruits, vegetables, dairy products, and grains. the model shows the chemical structures of three monosaccharides: glucose, fructose, and galactose. glucose \\(\ce{c6h12o6}\\) fructose \\(\ce{c6h12o6}\\) galactose \\(\ce{c6h12o6}\\) compare glucose, fructose, and galactose. chart with rows: has 12 hydrogen and 6 oxygen atoms, is a monosaccharide, has a 6-atom ring; columns: glucose, fructose, galactose; checkboxes in each cell submit

Explanation:

Step1: Analyze "has 12 hydrogen and 6 oxygen atoms"

The chemical formula for glucose, fructose, and galactose is \( C_6H_{12}O_6 \). So each has 12 H and 6 O atoms. So check all three (glucose, fructose, galactose) for this row.

Step2: Analyze "is a monosaccharide"

The problem states glucose, fructose, and galactose are monosaccharides. So check all three for this row.

Step3: Analyze "has a 6 - atom ring"

• Glucose: The structure shows a 6 - atom ring (5 carbons + 1 oxygen).
• Fructose: The structure shows a 5 - atom ring (4 carbons + 1 oxygen), so no.
• Galactose: The structure shows a 6 - atom ring (5 carbons + 1 oxygen). So check glucose and galactose for this row.

Answer:

	glucose	fructose	galactose
is a monosaccharide	✔️	✔️	✔️
has a 6 - atom ring	✔️	❌	✔️
