Which of the following is a trait of metabolic syndrome associated with type 2 diabetes?

High blood sugar is indeed a trait of metabolic syndrome associated with type 2 diabetes. Metabolic syndrome encompasses a cluster of conditions, including increased blood pressure, high blood sugar, excess body fat around the waist, and abnormal cholesterol levels, which together increase the risk of heart disease, stroke, and diabetes. In particular, elevated blood sugar levels indicate insulin resistance, a common factor in type 2 diabetes, where the body's cells become less responsive to the hormone insulin. This insulin resistance leads to higher glucose levels in the bloodstream.

In contrast, low cholesterol and low blood pressure are generally not characteristics of metabolic syndrome; instead, metabolic syndrome is often linked to higher levels of triglycerides and hypertension. Increased energy expenditure does not align with the traits commonly associated with metabolic syndrome, as this condition is more closely tied to obesity and sedentary behavior, which may result in a lower overall energy expenditure rather than an increase. Therefore, high blood sugar stands out as a significant and defining feature of metabolic syndrome in the context of type 2 diabetes.
