Which is the proper order of substrates in the synthesis of starch?
A)Glucose 1-phosphate → glucose 6-phosphate → ADP-glucose → starch.
B)Glucose 1-phosphate → fructose 6-phosphate → UDP-fructose → starch.
C)Glucose 3-phosphate → glucose 1-phosphate → ADP-glucose → starch.
D)Glucose 6-phosphate → glucose 1-phosphate → ADP-glucose → starch.

Question

Quizplus · Accepted Answer

The proper order of substrates in the synthesis of starch is glucose 6-phosphate → glucose 1-phosphate → ADP-glucose → starch. This pathway is known as the ADP-glucose pathway and is the major pathway for starch biosynthesis in plants. Therefore, choice D is the correct answer.
