The 'fight or flight' response to threatening -sympathetic (motor neurones) stimulated
environmental stimuli is coordinated by the nervous -noradrenaline/norepinephrine
and endocrine systems. -neurotransmitter released at neuromuscular junction/organs
-adrenaline secreted/released into blood
Describe and explain how the activation of the 'fight or -from adrenal glands/medulla
flight' response affects voluntary, involuntary and -adrenaline/noradrenaline binding to receptors (on target tissues)
cardiac muscle.
-heart beats faster
(in your answer, for each type of muscle, you should -heart beats more forcefully
give a named structure in which it is found and explain -alter blood flow/increase blood pressure
how the nervous and endocrine systems affect its -less blood flow to gut/skin
response.) -reducing gut secretions/making skin paler
-smooth muscle in gut relaxes/peristalsis slows down
-smooth muscle in airways relaxes/airways wider
-iris radial muscle contracts/pupil dilates
-breathing/intercostals/diaphragm contracting faster
-more blood flow to skeletal muscles
-muscles primed for action

Adrenaline acts on a variety of cell types with a variety SAN - increases rate of firing impulses - circulates blood more quickly

Describe the sequence of actions that occur once -catalyses synthesis of cyclic AMP from ATP.
adenylyl cyclase is activated in the target liver cells. -cyclic AMP activates enzymes responsible for conversion of glycogen to
glucose.

The response to adrenaline also occurs when a person - prolonged higher blood glucose concentration can lead to diabetes
is subjected to stress. However, the body doesn't need - prolonged high blood pressure can lead to cardiovascular problems
to respond physically to the stimulus and so, for - suppression of immune system can lead to susceptibility to disease/infection.
example, the bronchioles don't dilate.
Suggest the long term adverse effects of continued
exposure to stress on body function.
Athletic sprinters require large amounts if energy in -cells are able to tolerate high levels of lactate
short periods of time. Many elite sprinters can run 100 -have high phosphocreatine stores
metre races in under 10 seconds. - use of stored ATP
Under normal conditions, exercise requires an
increased rate of breathing. It has been observed that
some of the best sprinters only take one breath at the
start of the race and don't inhale again until the end of
the race.
Suggest how these sprinters can expend so much
energy without needing to carry out aerobic
respiration.
Most of the ATP produced in aerobic respiration is oxidative phosphorylation.
