Grave's disease is caused by the overproduction of immunoglobulins that mimic the shape of TSH and thereby bind to the TSH receptors. What is the expected hormonal change to the overproduction of TSH mimicking immunoglobulins? Select one: a. a decrease in the production of TSH, leading to a decrease in the metabolic rate b. an increase in metabolic rate, leading to a decrease in the production of TRH c. a decrease in metabolic rate, leading to an increase in the production of TSH d. an increase in the production of TRH, leading to an increase in the metabolic rate
