Question

Which equation shows a disaccharide with the monosaccharides that make it up?
A: sucrose = glucose + fructose
B: cellulose = glucose + glucose
C: lactose = sucrose + fructose
D: maltose = glucose + fructose

Answer 1

sucrose: glucose + fructosesucrose is a disaccharide made from glucose and fructose

glucose: C(sub 6)H(sub 12)O(sub6)fructose: C(sub 6)H(sub 12)O(sub6)
sucrose: C(sub 12)H(sub 22)O(sub 11)
a water molecule, H(sub 2)O gets removed which is why there are 2 less hydrogens and one less oxygen. Hope this helps!

Answer 2

The answer is A,) sucrose=glucose + fructose

Just got a 100%
