The use of enzymes is necessary to increase the activation energy requirements of a chemical reaction. true or false?

The right answer is False.

Activation energy is a concept introduced by S. A. Arrhenius, after having noted the empirical law that bears his name and which describes the evolution of a chemical reaction rate with temperature. In his law, there appears a term which has the dimension of a molar energy and which it calls activation energy.

Enzymes facilitate the completion of a chemical reaction by decreasing the activation energy (it allows the reaction to start more easily and accelerate it).

endo:

regulates body hormones, aldosterone, vasopressin

neural:

signal, regulates body using electric signals, reflex

endo has to do with hormones; aldosterone and vasopressin are both hormones. i also had this question and got it right : d
