True or False - True What concept between heart rate and performance which examines the optimal heart rate zone for optimal performance? - Inverted-U Law What is the optimal performance heart rate? - 115 to 145 BPM What are the food t...

activation energy energy needed to get a reaction started Delta G (change in G - change in free energy) respresented in a reaction coordinate diagram. Positive is thermodynamically unfavorable. Negative is thermodynamically favorable (exergonic - release energy). = G(products) - G(reactants) enzyme catalyze chemical reaction. Lower activation energy. Biological catalyst (protein) enzyme inhibition results in decrease in activity of that enzyme, reaising activation enregy...

dependent upon the overall order of the reaction The units for a rate constant, k, are: dependent upon the overall order of the reaction a rate constant is unitless M^-1 M^-1 s^-1 s^-1 the fraction of collisions with total kinetic energy greater than Ea increases. An increase in the temperature of the reactants causes an increase in the rate of reaction. The best explanation for this behavior is that as the temperature increases, the collision frequency increases. the fraction of coll...
