21
Q

Enumerate 3 Relationship or Interaction of hormones to target cells:

A
  1. Permissiveness
  2. Synergism
  3. Antagonism
22
Q

when 1 hormone cannot exert its full effect without another hormone being present

A

Permissiveness

23
Q

more than one hormone produce same effects on target cells

24
Q

one hormone opposes the action of another hormone

A

Antagonism

25
Target Cell Specificity response depends on
-Blood levels of hormones -number of receptors -Affinity of receptors to hormones
26
Chemical Categories of steroids
Hydrophobic
27
Chemical Category of Polypeptides
Hyrophilic(water soluble)
28
Chemical Category of amino acud derivatives
It depends
29

30
Mechanism of Hormone Action: (2 pts)
1. Cell Surface Receptors 2. Nuclear Receptors
31
Produce changes in membrane permeability
Cell Surface Receptors
32
Mechanism of hormonee. action as cell ssurfacee receptor
- Produce changes in membrane permeability - Stimulate synthesis of proteins or regulatory molecules - Activate or deactivate enzymes - Induce secretory activity and stimulate mitosis

Polypeptides
34
Chemical Category of Epinephrine, Norepinephrine, T3, T4
Amino acid Derived
35
diffuse into the cell, where it binds to intracellular receptors, migrate to nucleus and activate specific target sequences of DNA
Nuclear Receptors
