Identify the intermediate in the phosphoglucomutase reaction.

Short Answer

Expert verified

The intermediate in the phosphoglucomutase reaction is Glucose-1,6-bisphosphate.

Step by step solution

01

Introduction

Phosphoglucomutase is an enzyme that participates in a reversible phosphate group transfer process. The enzyme phosphoglucomutase adds a phosphate group to the substance when it is phosphorylated, and it removes the phosphate group when the chemical is dephosphorylated.

02

Intermediate in the phosphoglucomutase reaction

Phosphoglucomutase is a reversible enzyme that transfers the phosphate group from position 1 to position 6 in a reversible process. Phosphoglucomutase is responsible for the conversion of glucose-1-phosphate to glucose-6-phosphate and vice versa.

During the reversible interconversion, an intermediate is formed, containing two phosphate groups.Glucose-1,6-biphosphate serves as an intermediary molecule in this process.

How does phosphorylation differ between the kinase-catalyzed reactions and the reaction catalyzed by GAPDH?

Bacterial aldolase does not form a Schiff base with the substrate. Instead, it has a divalent Zn2+ion in the active site. How does the ionfacilitate the aldolase reaction?

Summarize the types of catalytic mechanisms involved. Do any glycolytic enzymes require cofactors?

Arsenate (AsO₄³⁻), a structural analog of phosphate, can act as a substrate for any reaction in which phosphate is a substrate. Arsenate esters, unlike phosphate esters, are kinetically as well as thermodynamically unstable and hydrolyze almost instantaneously. Write a balanced overall equation for the conversion of glucose to pyruvate in the presence of ATP, ADP, NAD⁺, and either (a) phosphate or (b) arsenate. (c) Why is arsenate a poison?

Some organisms can anaerobically convert glycerol to pyruvate. Could homolactic or alcoholic fermentation regenerate sufficient NAD⁺to support this pathway?
