Answer
This statement is incorrect. Glucose and fructose are not optical isomers; they are structural isomers with different molecular structures.
Step 2

Answer
This statement is true. Glucose serves as a primary monomer that the body uses to produce energy and is involved in various metabolic processes.
Step 3
C. 2 mol of glucose has the same energy content as 1 mol of sucrose.

Answer
This statement is also incorrect. While both glucose and sucrose provide energy, 2 moles of glucose will have a higher energy content than 1 mole of sucrose because glucose is more energy-dense.
Step 4
D. Sucrose has an energy output almost 200 times the energy output of aspartame.

Answer
This statement is misleading. The energy output of sucrose is significantly higher than that of aspartame, but it is not accurate to say it is 200 times greater. The sweetening power of aspartame is much stronger, but it provides fewer calories.
