Final answer:
During the exhaustion phase of the general adaptation syndrome, the body's energy does not begin to increase, but rather continues to deplete, leading to increased vulnerability to health issues.
Step-by-step explanation:
All of the following occur during the exhaustion phase of the general adaptation syndrome (GAS) except the body's energy begins to increase. The exhaustion phase is the third stage in the GAS model, developed by Hans Selye, which describes the body's response to stress. In the exhaustion phase, prolonged stress has led to a depletion of the body's resources. During this stage, the body experiences hormonal exhaustion, becomes more prone to illness, and there is an increased chance of experiencing collapse. However, the body's energy does not begin to increase; instead, it continues to deplete further, potentially leading to health issues such as depression, immune suppression, and fatigue.
