Question

In the pathway that plants use to synthesize starch, when glucose 1-phosphate reacts with ATP, what are the products of the reaction?

Group of answer choices

Glucose diphosphate

ADP Glucose triphosphate and

AMP Glucose

and adenosine tetraphosphate ADP-glucose

and inorganic pyrophosphate

Answer 1

During starch synthesis in plants, Glucose-1-phosphate uses an ATP and form ADP-Glucose + PPi ( inorganic pyrophosphate) with the help of enzyme ADP glucose pyrophosphorylase.

Inorganic pyrophosphate breaks down into 2 inorganic phosphates by enzyme pyrophosphatase.

The reaction is given below.

So last option is correct.The product of that reaction is ADP glucose and inorganic pyrophosphate.
