What is a primary outcome of glycogenolysis, mediated by Beta 2 receptors?

The primary outcome of glycogenolysis, especially when mediated by Beta 2 receptors, is the increased blood sugar levels. Glycogenolysis is the process through which glycogen, a stored form of glucose in the liver and muscles, is broken down into glucose. This process is stimulated by the activation of Beta 2 adrenergic receptors, typically in response to stress or low blood sugar levels.

When these receptors are activated, they signal the liver to release more glucose into the bloodstream, thus elevating blood sugar levels. This increase in glucose is critical for providing energy to various tissues, especially during times of heightened physical demand, such as during exercise or stress. Therefore, the activation of Beta 2 receptors plays a significant role in ensuring that the body's energy needs are met by augmenting the availability of glucose in circulation.

In contrast, the other options do not accurately represent the primary outcome associated with glycogenolysis mediated through Beta 2 receptors. While increased blood flow to skeletal muscles can occur during stress responses, it is not a direct outcome of glycogenolysis itself. Similarly, decreased blood pressure and decreased heart rate are not relevant results of glycogenolysis; rather, they typically occur under different physiological contexts or mechanisms
