Answer:
Option E
Explanation:
Complete question is
Why would you expect the energy present in the bonds of glucose to be more readily available than the energy from the sugar lactose?
a. It is easier to break down glucose into its component monosaccharides.
b. Glucose has fewer double bonds than lactose, making it easier to break down.
c. Both glucose and lactose are simple sugars; some people, however, have difficulty breaking down lactose.
d. Lactose is a complex carbohydrate and requires a lot of breaking down before the energy can be accessed.
e. Glucose is a simple sugar, and no additional processing is necessary to access the energy in the carbon-hydrogen bonds
Solution -
The structure of glucose is very simple as it is a monosaccharide i.e it has only one sugar molecule. On the other hand the lactose is disaccharide which means it has two sugar molecules. Being a monosaccharide, glucose cannot be further broken down into simple sugar molecules while on the other hand lactose can be broken down into simpler sugars (monosaccharide) by input of energy.
Thus, glucose is readily available carb based energy resources which can be directly converted into energy or converted into glycogen for storage in cells.
Thus, option E is correct
