However, research has shown that approximately 20% of overweight individuals are successful at long-term weight loss when defined as losing at least 10% of initial body weight and maintaining the loss for at least 1 y.he National Weight Control Registry provides information about the strategies used by successful weight loss maintainers to achieve and maintain long-term weight loss. National Weight Control Registry members have lost an average of 33 kg and maintained the loss for more than 5 y.
Which definition best describes the term activation energy? Which definition best describes the term activation energy? a) the energy required to remove an electron from a gaseous atom. b) the minimum kinetic energy that particles must possess for a chemical reaction to occur.
The activation energy is a term coined by the Swedish scientist, Svante Arrhenius in 1889. It means the amount of energy expressed in joules that is required to convert the molecules in one mole of a reactant from a ground state to the transition state. It can also mean the energy that an atomic system must have before an emission or chemical reaction can occur. The activation energy of a reaction may be denoted by E a. In relation to biology (such as biochemistry), the activation energy (or energy of activation) pertains to the energy needed to initiate a reaction. For instance, the activation energy required to breakdown glucose into pyruvic acid in respiration is two ATP.
