HCN
Ka = 6.2 x10-10
General Adaptation Syndrome
According to Hans Selye, a series of physiological reactions to stress occurring in three phases: alarm, resistance, and exhaustion.
Resistance Phase
The second stage of the general adaptation syndrome, where the body adapts to and resists stress, but at a high cost to its energy resources.
Exhaustion Phase
The final stage of the general adaptation syndrome, characterized by the body's inability to continue adaptation to stress, leading to potential burnout or health issues.
Alarm Phase
The initial reaction of the body to stress, activating the sympathetic nervous system and the release of stress hormones.
