This effect is mediated by stimulating tubular reabsorption of calcium. Another effect of parathyroid hormone on the kidney is to stimulate loss of phosphate ions in urine.

Physiologic Effects of Parathyroid Hormone Writing a job description for parathyroid hormone is straightforward: if calcium ion concentrations in extracellular fluid fall below normal, bring them back within the normal range.
The term activated complex refers to the molecular compound or compounds that exist in the highest energy state, or activated stage, during a chemical reaction. An activated complex acts as an intermediary between the reactants and the products of the reaction. A chemical reaction is the reorganization of atoms of chemically compatible and chemically reactive molecular compounds, called reactants.
why is an activated complex sometimes called the transition state. there is a brief existence that ends with the reformation of the reactants or with the formation of products. changes in the rate of chemical reactions depend on conditions such as. temperature, concentration, surface area, catalyst. the main effect of increasing the temperature of a chemical reaction is to ___ the number of particles that have enough kinetic energy to react when they collide.
