Which of the following typically occurs during a stress response?

During a stress response, the body activates a range of physiological changes aimed at mobilizing resources to manage the perceived threat or challenge. One of the key components of the stress response is the mobilization of nutrients from storage to ensure that the body has adequate energy and resources to respond effectively. This process typically involves the release of hormones, such as cortisol and adrenaline, which stimulate the breakdown of glycogen (stored glucose) in the liver and the release of fatty acids from adipose tissue. Such mobilization provides quick access to energy and essential nutrients required to support heightened metabolic demands associated with the stress response.

In contrast, options like increased nutrient storage and lower heart rate and respiration reflect physiological states that are more geared toward rest and recovery rather than the active response required during stress. Lower blood pressure also does not align with the body's reaction to stress; instead, stress typically results in elevated blood pressure and heart rate as part of the fight-or-flight response.
