Question

The two thyroid hormones, thyroxine and triiodothyronine, have complementary effects in which they decrease the rate of cellular metabolism and oxygen consumption in almost every cell in the body.
a. True
b. False

Answer 1

Answer:

False

Explanation:

The thyroid gland secrete two thyroid hormones called thyroxine and triiodothyronine. Thyroxine is the in active form which is later converted to the active form triiodothyronine by kidneys and livers. The two hormones function by increasing the metabolic activities of tissues. They increase the body heat production which in turn increase oxygen consumption and ATP hydrolysis because they burn body fat thereby increasing energy production and increasing basal metabolic rate. They regulate body temperature.
