Q

NE synthesis

A

Tyrosine —[tyrosine hydroxylase]–> DOPA –> dopamine –> NE

2
Q

What transporters are responsible for NE reuptake?

A

NET (NE transporter) and DAT (DA transporter)

3
Q

if NE is not taken up by NET and DAT, what 2 compounds may metabolize it?

A

MAO (monoamine oxidase)

COMT

products are then excreted

which receptor does the parasympathetic system act on to cause bronchoconstriction?

A

M3 receptor

8
Q

sympathetic receptor associated with SA node

A

acceleration via beta1 (also beta2 but primarily 1)

9
