Final answer:
Exercise is actually beneficial in managing blood glucose levels as it increases insulin sensitivity, helping to lower blood sugar and reducing the risk of type 2 diabetes.
Step-by-step explanation:
The statement that exercise helps control blood glucose because it decreases insulin sensitivity is false. In reality, regular physical activity increases insulin sensitivity, which helps lower blood sugar levels and improves the ability of insulin to function effectively. This, in turn, reduces the risk of type 2 diabetes. Moreover, exercise assists in maintaining healthy body weight, stimulates the metabolism of glucose to generate ATP, and aids in reducing blood glucose by promoting the liver to convert excess glucose into glycogen for storage. People with type 2 diabetes are encouraged to exercise regularly as a part of their management plan to prevent the progression of the disease or to potentially reverse it.
