What does glucose refer to?

a monosaccharide sugar that has several forms
a gasoline substitute consisting of 90% gasoline and 10% grain alcohol from corn
digestive secretions of the stomach glands consisting chiefly of hydrochloric acid and mucin and the enzymes pepsin and rennin and lipase
underground water that is held in the soil and in pervious rocks

The correct answer is: a monosaccharide sugar that has several forms

Glucose refers to a type of monosaccharide sugar, meaning it is a simple sugar molecule made up of only one sugar unit. This type of sugar can also exist in multiple forms, such as alpha and beta glucose. Option B is incorrect as it describes ethanol, not glucose. Option C refers to gastric juices and option D refers to groundwater, which are not related to glucose.
