What happends to an enzyme when it is exposed to temperatures above or below its optimal temperature

structure begins to break down (denature)

The particles with high kenetic energy

Explanation:

The first particles to evaporate from a liquid are those with the highest kinetic energy. When a liquid absorbs thermal or sound energy, its molecules speed up giving them higher kinetic energy. Typically, the particles or molecules at or just under the surface of the liquid escape into the gas phases first

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
