(B) cane sugar gives equal amount of glucose and fructose.
(C) milk sugar gives glucose and galactose.
(D) amylopectin gives glucose and fructose.
(E) amylose gives only glucose.
Choose the correct answer from the options given below :
Select the correct option:
A
(B), (C) and (D) only
B
(A), (B) and (C) only
C
(C), (D) and (E) only
D
(B), (C) and (E) only
✓ Correct! Well done.
✗ Incorrect. Try again or view the solution.
Solution
(A) Starch $\xrightarrow{\mathrm{H}^{+} / \mathrm{H}_{2} \mathrm{O}}$ Glucose
(B) Cane sugar $\xrightarrow{\mathrm{H}^{+} / \mathrm{H}_{2} \mathrm{O}}$ glucose + fructose
(Sucrose) 50\% 50\%
(C) Milk sugar $\xrightarrow{\mathrm{H}^{+} / \mathrm{H}_{2} \mathrm{O}}$ glucose + galactose
(Lactose)
(D) Amylopectin $\xrightarrow{\mathrm{H}^{+} / \mathrm{H}_{2} \mathrm{O}}$ Glucose
(E) Amylose $\xrightarrow{\mathrm{H}^{+} / \mathrm{H}_{2} \mathrm{O}}$ Glucose
So, correct options are B, C and E only
