Question

Which of the following is required for conversion of 3PGAL and dihydroxy acetone phosphate to fructose 1, 6 diphosphate
A) Transketolase
B) Aldolase
C) Phosphatase
D) Hexokinase

Answer 1

Which of the following is required for conversion of 3PGAL and dihydroxy acetone phosphate to fructose 1, 6 diphosphate
A) Transketolase

Answer 2

Solution:

Aldolase is required for the conversion of 3 PGAL and dihydroxyacetone phosphate to fructose 1, 6 diphosphates.

Explanation:

• Transaldolase is used to catalyze the reversible condensation of glyceraldehyde 3-phosphate that is 3 PGAL with dihydroxyacetone phosphate to obtain fructose 1,6-bisphosphate.
• Option a is incorrect because transketolase catalyzes the conversion of fructose 6 phosphates into erythrose 4 phosphate.
• Option c is incorrect because phosphatase serves in the removal of a phosphate group from its substrate by hydrolysis.
• Option d is incorrect because hexokinase phosphorylates hexose sugar into hexose phosphate.
• Hence, option b aldolase is correct.
