Question

What makes a reaction a candidate for a flux control point? Describe how the elasticity coefficient of a reaction correlates with flux control. (5 points)

Answer 1

The Elasticity Coefficient, in contrast to the flux and concentration control coefficients, which are properties of the system, is a local property and can be measured using isolated enzyme and substrate. It makes sense that some kinetic property of the isolated enzyme would affect its propensity to affect system flux.

The elasticity coefficient gives a measure of how much a substrate S (or other substance) can change the reaction rate (v) of an isolated enzyme.
