Summary Introduction

To analyze: ATP that is considered to be an allosteric regulator of phosphofructokinase inhibits or stimulates the activity of this enzyme.

Introduction:

Phosphofructokinase is the most important regulatory enzyme in glycolysis, converting fructose-6 phosphate to fructose-1,6 bisphosphate. Its regulation is allosteric, with adenosine triphosphate (ATP) acting as the allosteric regulator. This enzyme plays a key role in the energy investment step of glycolysis.

Focusing on the mechanism linking complex I and ATP synthase depicted in figure 3 in the article, compare that hypothetical mechanism to the classical presentation described in textbooks. What are the major differences between this mechanism and Peter Mitchel’s original chemiosmotic theory? What are the similarities.

. In another key reaction in glycolysis, dihydroxyacetone phosphate (DHAP) is isomerized into glyceraldehyde-3-phosphate (GAP) Because ∆G°′ is positive, the equilibrium lies to the left. (a) Calculate the equilibrium constant and the equilibrium fraction of GAP from the above, at 37 °C. (b) In the cell, depletion of GAP makes the reaction proceed. What will ∆G be if the concentration of GAP is always kept at 1/100 of the concentration of DHAP?
