Question

Quizplus · Accepted Answer

When more energy is required by a human, blood glucagon increases. This hormone promotes the breakdown of stored glycogen in the liver, leading to the release of glucose into the bloodstream for energy. Insulin, on the other hand, promotes the storage of glucose and other nutrients, so its levels decrease when more energy is required. Thyroid hormone levels may increase in response to an increased energy demand, but this is not directly related to glucose metabolism. The information provided in the question about mouse mutations and the ob and db genes is not relevant to this question.
