During the "Fight or Flight" response there is:

Question

BlackTom AI · Accepted Answer

In the context of the Fight or Flight response, the body shifts physiology to prepare for rapid action. 
Option A: decreased mental alertness. On the contrary, there is an increase in mental alertness and cognitive readiness to assess threats, driven by sympathetic activation and adrenal output. A drop in alertness would undermine quick decision-making, making this option unlikely. 
Option B: increased urine production. The sympathetic nervous system generally inhibits bladder function and reduces urine production during acute stress, conserving body fluids for immediate needs. An increase in urine output would be counterproductive in a fight-or-flight scenario, so this choice is incorrect. 
Option C: decreased respiration rate. During Fight or Flight, respiration increases to supply muscles and brain with more oxygen. A decreased respiration rate would limit oxygen delivery, which does not align with the physiological aim of the response. This makes the option inaccurate. 
Option D: decreased blood flow to skeletal muscles and skin. In reality, blood flow to skeletal muscles increases to enhance performance, and blood flow to the skin often changes to support heat dissipation and alertness. Reducing flow to these areas contradicts the purpose of rapid physical action, so this statement is false. 
Option E: mobilisation of energy reserves. This is a core feature: glycogenolysis and lipolysis mobilize glucose and fatty acids to fuel muscles and tissues during acute stress, enabling rapid action. This aligns precisely with the Fight or Flight mechanism. 
Overall, each of A through D describes physiological directions that oppose the adaptive priorities of Fight or Flight, whereas E matches the intended energy mobilization that supports quick, powerful responses.
