Question

G-1-P is then ______________ for entry into metabolic mainstream:

G-1-P -> G-6-P
a. By __________
b. Rxn type: __________
c.Reversible rxn, but favors product G-(1/6?)-P over G-(1/6?)-P

Answer 1

G-1-P is an intermediate in glycolysis and is converted to G-6-P through an isomerization reaction catalyzed by phosphoglucomutase. The reaction is reversible but favors the formation of G-6-P. This conversion is an important step in the metabolic process.

Step-by-step explanation:

G-1-P is an intermediate in the process of glycolysis. It is converted to G-6-P, which is then used as a substrate in the metabolic mainstream. This conversion is catalyzed by the enzyme phosphoglucomutase. The reaction is an isomerization reaction, where G-1-P is converted to G-6-P through the transfer of a phosphate group.

The reaction is reversible, but it favors the formation of G-6-P over G-1-P. This means that, under normal cellular conditions, the concentration of G-6-P will be higher than that of G-1-P. The formation of G-6-P is energetically favorable, contributing to the overall efficiency of glycolysis.
