Question 14

Lactic acid is a hormone that increases circulating concentrations due to high-intensity exercise.

Question 15

The system of testosterone regulation in females is different than the system in males.

Question 16

The hormonal response to exercise is normally intensity-dependent.

Question 17

Antidiuretic hormone (ADH) and aldosterone work by different mechanisms.

Question 18

Humans experience hormonal variations based on the time of year (seasonal variation).

Question 19

When binding proteins are involved, the total hormone concentration includes the free and _______ concentrations of the hormone.

Question 20

The _____________ method of transporting hormones means that the compound remains in the cell to influence the activity of the cell in some manner.

Question 21

_________________ refers to hormones that are released into the bloodstream or lymph system following stimulation of the nervous system.

Question 22

_________________ are the cellular structures to which the hormones bind, resulting in the appropriate action at the cell.

Question 23

________________ refers to an increase in the number of receptors on the surface of target cells, making the cells more sensitive to a hormone or other molecule.
