Stimulation of glucose production and release into circulation to provide a quick fuel source for muscle tissue so that the body is readied for action during a stress event.
Option B.
<h3><u>Explanation:</u></h3>
Cortisol is a steroid group of hormone that is secreted from the Adrenal Cortex from the zona fasciculata. It's the middle layer of Adrenal Cortex. Cortisol helps in different functions of the body that includes the suppression of immune system, increasing the blood sugar level, gluconeogenesis, metabolism of fat, and proteins. This hormone helps in the gluconeogenesis which helps to produce glucose from non glucose sources. The primary sources include the fats and proteins and the glycogen reserve in liver and muscles. Thus increase in cortisol levels help in the retaining glucose levels in stress or hypoglycemia.
The correct answer among the choices provided is option A. Lung capillaries are responsible for exchanging carbon dioxide for oxygen from the air. Blood that comes from the heart gets oxygen from the alveoli. The carbon dioxide in the blood goes into the alveoli at the same time.
There are so many examples for that in different areas, like TPBA experiment carried out in our lab recently.Here's one link: http://www.alfa-chemistry.com/tpba-cas-172285-72-2-item-294462.htm
