Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
these are converted to glucose for use by body cells
A
fructose
B
ribose
C
galactose
D
deoxyribose
Explanation: 

Detailed explanation-1: -After absorption from the alimentary canal, much of the fructose and almost all of the galactose is rapidly converted into glucose in the liver.

Detailed explanation-2: -Galactose is one of the monosaccharides of importance in human nutrition. It is converted to glucose-1-phosphate in the liver and subsequently stored as glycogen, or is converted to glucose and released into the circulation.

Detailed explanation-3: -In normal conditions, galactose is quickly and almost completely metabolized to glucose in the liver. Galactose serves as a substrate for cerebrosides, gangliosides and mucoproteins in the brain and nervous system, which supports its neural and immunological role [2, 3, 6, 7].

Detailed explanation-4: -Galactose can be converted to glucose-6-P, after which it can be used for glycogen synthesis; or it can be oxidized further to form PYR or acetyl-CoA for additional energy generation or fatty acid synthesis. Galactose is initially phosphorylated by galactokinase to form galactose-1-phosphate (galactose-1-P).

Detailed explanation-5: -Galactose is a monosaccharide. When combined with glucose (another monosaccharide) through a condensation reaction, the result is a disaccharide called lactose.
