Q

low levels of serotonin will cause…

A

worry/depression + constipation

17
Q

changes in bowel motility indicates serotonin is…

A

produced in the gut

18
Q

histidine

reaction

A

histidine -> histamine

enzyme = decarboxylase (B1)

19
Q

histidine

functions

A
  • H1 receptors in capillary & hypothalamus = vasodilation & release ant. pituitary hormones
  • H2 receptors in parietal cells = release stomach acid
20
Q

glutamate

function

A

important excitatory NT in CNS (Mg is gate keeper)

Mg slows Na/Ca intake

21
Q

glutamate

excitatory reaction

A

binds to NMDA receptors

22
Q

glutamate is part of…

A

glutathione
SGPT

23
Q

glutamate

inhibitory reaction

A

glutamate -> GABA (helps focus)

requires decarboxylase, B1, B6

24
Q

function of glycine

A

inhibitory NT in skeletal muscle interneurons

25
Q

serine

reaction

A

serine -> choline

requires B6, B9 (folic acid), B12

26
Q

serine

choline reaction

A

choline + Acetyl CoA -> acetyl choline

27
Q

arginine

function

A

vasodilation

28
Q

arginine

reaction

A

arginine -> citrulline
(makes NO)
