Sergeu [11.5K]
<span>The correct answer is c. ​hypothalamus to pituitary gland to adrenal glands.
</span>
When it comes to stress, hypothalamus-pituitary-adrenal axis (HPA) is responsible for stress response. Hypothalamus releases corticotropin-releasing hormone (CRH) which binds to its receptors on the anterior pituitary gland. As a result, adrenocorticotropic hormone (ACTH) is released and it stimulates the release of cortisol from the adrenal gland. At a certain levels of cortisol, this steroid hormone exerts negative feedback to the hypothalamic release of CRH.

Which statement describes the reaction for cellular respiration?
mixer [17]

The equation is glucose + oxygen carbon dioxide + water and energy is produced in the form of ATP.

Explanation:

Cellular respiration is a metabolic process in which glucose combines with oxygen to produce carbon dioxide and water with energy stored as ATP.

    Glucose + Oxygen gas → Carbon dioxide + Water + energy in ATP

ATP is Adenosine TriPhosphate.

In the body, during cellular respiration, oxygen gas is inhaled and carried to sites in the body where food in form of glucose obtained from plant is broken down.

When food is broken down aerobically i.e in the presence of oxygen gas, carbon dioxide and water is produced and energy is stored in form of ATP.
