Answer #1

1)Thermodynamic Potentiality- represent the thermodynamic state of a system.It is the ability to release stored chemical energy.

Eg,Glucose can be viewed as an E-rich compound.I t reprezent thermodynamic potentiality-its reaction with oxygen is exergonic,but it doesnt occur at normal conditions.

2)This means that Enzymes control the rates at which certain reactions release their energy.

Kinetic control describes only how fast the reaction can proceed;the catalyzed reaction has lower activation energy and proceed faster,t hus the enzyme is exerts kinetic control over thermodynamic potentiality.

The term describes only the free energy between an uncatalyzed reaction and a catalyzed reaction.

    We recently used an enzyme in the laboratory: lactase. I have also often used the metaphor "Goldilocksian" to describe the catalysts we call enzymes. Our results in our experiments did not exactly show the traditional relations of enzymes to different levels of pH and temperature. Thus, I provide here a "theoretical" set of data (closer to what would be seen with more ideal conditions).

    We have just enough time to get our bearings when we see a huge enzyme (called hexokinase) closing in. We are wrapped into the active site of the enzyme.
