Answer:
If you inhibit thyroid hormones with PTU (propylthiouracil) in mice the metabolic rate will increase A low temperature the mice will shiver to maintain body temperature, which will cause the oxygen consumption to increase.
Explanation:
In an experiment involving rmice fed with normal food and those fed with with food containing PTU (propylthiouracil), it will be observed that the the metabolic rate of the mice fed with the PTU diet will be faster than that of mice fed with normal food.
This is because PTU inhibits the action of thyroid hormones whose function is to regulate the body's metabolic rate by controlling heart, muscle and digestive function, as well as brain development and bone maintenance.
Also, if the chamber containing the mice were cooled, it will be observed that the mice will shiver in order to maintain its body temperature. This shivering will increase the metabolic rate of the mice, and hence oxygen consumption will increase as well.
If you inhibit thyroid hormones with PTU in mice the metabolic rate will INCREASE. A low temperature the mice will shiver to maintain body temperature, which will cause the oxygen consumption to INCREASE.
- Propylthiouracil (PTU) is a medication used to inhibit the production of thyroid hormone in the thyroid gland.
- In mice, this medication (PTU) causes a reduction in weight by increasing metabolic rate.
- Moreover, an increase in metabolic rate to maintain body temperature will lead to higher consumption of oxygen, which is used during cellular respiration to produce energy and thus carry out metabolic functions.
In conclusion, if you inhibit thyroid hormones with PTU in mice the metabolic rate will INCREASE. A low temperature the mice will shiver to maintain body temperature, which will cause the oxygen consumption to INCREASE.
