What happens to glucose or galactose when the Cu2 plus in benedicts is reduced?

"All monosaccharides and most disaccharides can be oxidized. When the cyclic structure opens, the algehyde (-COOH) group is availabel for oxidation. Benedict's reagent contains Cu2+ ion that is reduced. Therefore, all the sugars that react with Benedict's reagent are called reducing sugars. When oxidation of sugar occurs, the Cu2+ is reducted to Cu+, which forms a red precipitate of cuprous oxide, CuO(s). The precipitates colors varies from green to fold to red depending on the concentration of the reducing sugar." Caralyst Pearson Custom Publishing 2011 p.65

Is glucose oxidized or reduced in cellular respiration?
Oxidized.
What is oxidized during the oxidation stage of cellular respiration?
Glucose is. In cell respiration, the carbon atoms of glucose are oxidized.
How many colours are observed in Benedicts test?
There are 4 colors that can be observed in Benedict's test. This is a test that is conducted to show if there is a presence of reduced sugars. This test is also referred to as Benedict's reagent.
what happens to a gas as pressure is reduced?
When the pressure of a gas is reduced it gets colder.
What happens with bromine?
bromine is reduced
Why is lactose converted into glucose and galactose during food processing?
Converting lactose into glucose and galactose allows lactose-intolerant people to consume milk products. Glucose and galactose also taste sweeter than lactose so the need for additional sweeteners in flavored milk products is reduced. As glucose and galactose are more soluble, it gives ice-cream a smoother texture. Glucose and galactose can be fermented by bacteria more quickly so the use of these monosaccharides shortens the production time of cottage cheese and yogurt.
Sucrase is an enzyme that breaks sucrose down into glucose and fructose what happens to the chemical bonds in sucrose when it binds to the enzyme sucrase?
Hydrolysis of the glycosidic bond results. Sucrose is reduced to glucose and fructose.
