It will mainly act via increasing instant energy in the blood for your Fight or flight response = primarily glucose response!! (you need energy to run fast)!! So it:
increase HR and force (so you can pump more blood)
increase the diameter of your airways (so you can get in more oxygen)
increase blood pumping to your, muscles, brain and heart (so you can run away! )
decrease blood to your intestines (= sinking feeling in your stomach)
increase muscle glycogen degradation (both activates the breakdown and prevents the synthesis) (it increases liver glycogen degredation too)
increases sweating
but it also increases fatty acid release from fat cells (if the stress is great enough then you get a great release of fat from your alpha receptor fat on your butt and thighs! )

However, you would have also then had a release of cortisol as well... Which is more of a 'long term solution' to the stress... So it is somewhat similar in that it releases energy - but via:
Increase fatty acid release from fat cells
increases amino acid release from muscle cells
stimulates the formation of glucose
