Final answer:
Thyroid hormones T4 and T3 bind to nuclear receptors inside the cells, not on the plasma membrane. Graves' disease causes overproduction of thyroid hormones. The primary function of T4 and T3 is to regulate the body's basal metabolic rate.
Step-by-step explanation:
The statement 'T3 and T4 bind to receptors on the plasma membrane of target cells' is false, as both thyroid hormones primarily bind to nuclear receptors inside the target cells, influencing gene expression and metabolic activities.
The disease that causes too much thyroid hormone to be produced is Graves' disease which is an autoimmune disorder that stimulates the thyroid to produce excess amounts of hormones, leading to hyperthyroidism.
If a person has hyperthyroidism and produces too much thyroid hormone, the level of TSH (thyroid stimulating hormone) is typically reduced due to the negative feedback mechanism that maintains homeostasis in the body, where high levels of thyroid hormones inhibit further production of TSH.
